Destruction des statues de la reine égyptienne Hatchepsout : une nouvelle étude conteste la vengeance

Source: The Conversation – in French – By Jun Yi Wong, PhD Candidate in Egyptology, University of Toronto

Après la mort de la reine pharaon égyptienne Hatchepsout vers 1458 avant notre ère, de nombreuses statues à son effigie ont été détruites. Initialement, les archéologues pensaient que son successeur, Thoutmosis III, avait agi par vengeance. Cependant, l’état des statues retrouvées à proximité de son temple funéraire varie et beaucoup ont survécu avec leur visage pratiquement intact.

Une nouvelle étude, menée par l’archéologue Jun Yi Wong, propose une autre explication. En se basant sur les fouilles anciennes, il suggère que les statues n’ont pas été détruites par haine. Il pense plutôt qu’elles ont été « désactivées » lors d’un rituel, puis recyclées comme matière première. Nous lui avons demandé de nous en dire plus.


Qui était la reine Hatchepsout et pourquoi était-elle importante ?

Hatchepsout a régné en tant que pharaon d’Égypte il y a environ 3 500 ans. Son règne fut exceptionnellement prospère : elle fut une bâtisseuse prolifique de monuments et son règne fut marqué par de grandes innovations dans les domaines de l’art et de l’architecture. C’est pourquoi certains la considèrent comme l’un des plus grands souverains de l’Égypte antique, hommes et femmes confonfus. Elle a également été décrite comme la « première grande femme de l’histoire ».

Hatchepsout était l’épouse et la demi-sœur du pharaon Thoutmôsis II. Après la mort prématurée de son mari, elle devient régente au nom de son beau-fils, le jeune Thoutmosis III. Cependant, environ sept ans plus tard, Hatchepsout accéde au trône et se proclame souveraine d’Égypte.

Pourquoi a-t-on cru que ses statues avaient été détruites par vengeance ?

Après sa mort, le nom et les représentations d’Hatchepsout, notamment ses statues, ont été systématiquement effacés de ses monuments. Cet événement, souvent appelé la « proscription » d’Hatchepsout, fait actuellement partie de mes recherches plus vastes.

Il ne fait guère de doute que cette destruction a commencé sous le règne de Thoutmôsis III. En effet, certaines représentations d’Hatchepsout, effacées puis dissimulées, ont été retrouvées derrière les nouvelles constructions qu’il avait fait ériger

Les statues sur lesquelles porte ma récente étude ont été découvertes dans les années 1920. À cette époque, la proscription d’Hatchepsout par Thoutmôsis III était déjà bien connue. Les archéologues ont donc tout de suite – et à juste raison – pensé que les statues avaient été détruites sous son règne. Certaines d’entre elles ont même été retrouvées sous une chaussée construite par Thoutmôsis III, ce qui confirme cette hypothèse.

Comme les statues ont été retrouvées en fragments, les premiers archéologues ont supposé qu’elles avaient dû être brisées violemment, peut-être en raison de l’animosité de Thoutmosis III envers Hatchepsout. Par exemple, Herbert Winlock, l’archéologue qui a dirigé les fouilles de 1922 à 1928, a remarqué que Thoutmosis III avait dû « décréter la destruction de tous les portraits (d’Hatchepsout) existants » et que

toutes les indignités imaginables avaient été infligées à l’effigie de la reine déchue.

Le problème avec cette interprétation est que certaines statues d’Hatchepsout ont survécu dans un état relativement bon, avec leurs visages pratiquement intacts. Pourquoi y a-t-il eu une telle variation dans le traitement des statues ? C’est cette question qui a guidé l’essentiel de mes recherches.

Comment avez-vous cherché à résoudre cette énigme ?

Il était évident que les dommages causés aux statues d’Hatchepsout n’étaient pas uniquement le fait de Thoutmôsis III. Beaucoup d’entre elles avaient été laissées à l’air libre et n’avaient pas été enterrées, et beaucoup avaient été réutilisées comme matériaux de construction. En effet, non loin de l’endroit où les statues ont été découvertes, les archéologues ont trouvé une maison en pierre partiellement construite à partir de fragments de ses statues.

La question est bien sûr de savoir dans quelle mesure ces réutilisations ont contribué à endommager les statues. Heureusement, les archéologues qui ont fouillé les statues ont laissé des notes de terrain assez détaillées.

Grâce à ces archives, il est possible de reconstituer les emplacements où bon nombre de ces statues ont été trouvées.

Les résultats sont surprenants. Les statues les plus abîmées, souvent dispersées sur de grandes surfaces ou incomplètes, présentent des visages fortement endommagés. En revanche, les statues trouvées dans un état relativement complet ont généralement le visage intact.

En d’autres termes, les statues qui ont été largement réutilisées sont beaucoup plus susceptibles d’avoir subi des dommages au niveau du visage.

Il est donc probable que Thoutmôsis III ne soit pas responsable des dommages subis par les visages des statues. Les dégâts qu’on peut lui attribuer semblent plus spécifiques : il aurait fait briser les statues au niveau du cou, de la taille et des genoux.

Ce type de traitement n’est pas propre aux statues d’Hatchepsout.

C’est fascinant. Mais alors, qu’est-ce que cela signifie ?

La pratique consistant à briser les statues royales au niveau du cou, de la taille et des genoux est courante dans l’Égypte ancienne. Elle est souvent appelée « désactivation » des statues.

Pour les anciens Égyptiens, les statues étaient plus que de simples images. Par exemple, les statues nouvellement créées étaient soumises à un rituel appelé « ouverture de la bouche », où elles étaient rituellement ramenées à la vie. Les statues étant considérées comme des objets vivants et puissants, leur pouvoir inhérent devait être neutralisé avant qu’elles puissent être jetées.

En effet, l’une des découvertes les plus extraordinaires de l’archéologie égyptienne est la Cachette de Karnak, où des centaines de statues royales ont été trouvées enterrées dans un seul dépôt. La plupart de ces statues ont été « désactivées », alors même qu’elles représentent des pharaons qui n’avaient subi aucune hostilité après leur mort.

Cela indique que la destruction des statues d’Hatchepsout était principalement motivée par des raisons rituelles et pragmatiques, plutôt que par la vengeance ou l’animosité. Cela change bien sûr la façon dont on comprend la relation entre Hatchepsout et Thoutmôsis III.

From athlete’s foot to smelly soles: why daily washing is key to healthy feet

Source: The Conversation – UK – By Dipa Kamdar, Senior Lecturer in Pharmacy Practice, Kingston University

Washing your feet might not top your list of daily priorities – but it should.

While most of us shower regularly, our feet are often forgotten. Letting water run over them isn’t enough. To keep them healthy, you need to actively wash your feet with soap and water, paying close attention to the soles and the spaces between your toes. This helps remove sweat, dead skin and microbes that build up throughout the day and helps prevent infections, irritation – and that all-too-familiar smell.

Feet, particularly the spaces between toes, are a breeding ground for bacteria and fungi. Thanks to socks, shoes, and sweaty soles, they spend most of the day in a warm, humid environment that’s perfect for microbial growth. This can lead to common conditions like athlete’s foot, fungal nail infections, and bromodosis (smelly feet).

Stinky feet

Sweat itself doesn’t smell. But when bacteria break down sweat on your feet, they release smelly compounds called volatile fatty acids (VFAs). Staphylococcus bacteria are key players here, feeding on amino acids in sweat and producing isovaleric acid, which smells distinctly cheesy or sour (fun fact: it’s the same compound found in certain cheeses).

A study found that 98.6% of bacteria on the soles of participants’ feet were Staphylococci, and the intensity of foot odour was directly linked to how much of this bacteria was present.

Good foot hygiene isn’t just about avoiding odour, though; it also helps prevent infections. Athlete’s foot, a fungal infection, thrives in the damp space between your toes. It causes itching, redness, cracked skin and sometimes blisters. And despite the name, you don’t have to be an athlete to get it. The infection spreads easily in communal places like swimming pools, showers and changing rooms, particularly if you go barefoot.

If left untreated, the fungus can spread to the toenails, making them thick, yellow and brittle. Catching it early makes treatment much easier.

Bacterial infections are also a concern, especially when Staphylococcus or Pseudomonas enter through small cuts or cracked skin. Washing regularly helps reduce the number of bacteria living on the surface, lowering the risk of infection for anyone with vulnerable or damaged skin.

Diabetic foot care

If you have diabetes, foot care becomes even more important. People with diabetes are more prone to ulcers and infections and wounds often heal more slowly, particularly when blood sugar levels are poorly controlled.

This is due to several factors: poor circulation means less oxygen and fewer nutrients reach the site of the wound, the immune response is weaker, and inflammation may persist. Nerve damage (diabetic neuropathy) in the feet can also mean that injuries go unnoticed – and untreated.

According to Diabetes UK, daily foot washing is a key part of diabetes care; not just to reduce infection risk, but to check for any early signs of damage, such as redness, swelling, or breaks in the skin.

Too clean?

If you’ve been in closed shoes all day, or exercising, a proper wash is a good idea. For most people, once a day is enough, particularly during warm weather.

But not everyone needs to scrub their feet daily. The skin is home to a healthy community of beneficial microbes that defend against harmful bacteria and support the skin’s natural barrier. Overwashing, particularly with hot water or harsh soaps, can strip these helpful organisms and remove natural oils, leaving skin dry, irritated and more prone to cracking.

This is especially problematic for people with skin conditions like eczema where the skin barrier is already weakened.

The use of antibacterial soaps can also disrupt the skin’s microbial balance, killing off friendly bacteria and potentially encouraging the growth of more harmful, antibiotic-resistant strains. Some scientists also suggest that excessive hygiene might reduce the immune system’s exposure to everyday microbes; exposure that helps build a healthy immune response.

How to wash your feet properly

Here’s how to do it right, according to NHS guidance:

  • use warm (not hot) water and a mild soap

  • wash thoroughly, paying close attention to the soles and between the toes

  • dry your feet completely, including the spaces between your toes

  • apply moisturiser to keep the skin soft and less likely to crack — but skip the areas between the toes, as added moisture there can encourage fungal growth

  • inspect your feet regularly for any signs of redness, swelling, or blisters — vital for those with diabetes.

If you notice persistent itching, unusual odours, or signs of infection, speak to a pharmacist. They can recommend over-the-counter treatments or refer you to a podiatrist if necessary.

Whether you’re active, managing a chronic condition, or just trying to stay fresh in summer, proper foot hygiene matters. It might seem like a small step – but it makes a big difference to your overall health.

What’s the forever chemical TFA doing in the UK’s rivers?

Most UK rivers are contaminated by a chemical called trifluoroacetic acid (TFA). This is a type of human-made chemical known as perfluorinated alkyl substances (PFAS), often called “forever chemicals”.

This widespread contamination highlights the extensive scale of work required to remove synthetic forever chemicals from our environment.

Many PFAS are known to be toxic (including associations with altered liver and thyroid function and various cancers). PFAS all contain at least two carbon-fluorine (C-F) chemical bonds, one of the toughest bonds to break so they tend to be persistent. Once they are released to the environment, they don’t easily degrade.

The PFAS class incorporates a vast but unknown number of different chemicals – estimates vary from around 5,000 to 6.5 million. TFA is just one of many PFAS.

TFA enters the environment from different sources. It’s used to make blowing agents (used to make things like expanded foams and plastics such as packaging materials), pesticides and pharmaceuticals. So it is intentionally used for some useful applications.

But it can also be produced unintentionally as a by-product from various processes that involve “pre-cursor” PFAS chemicals. The biggest environmental source of TFA is as a by-product from manufacturing “F-gases” or flourinated greenhouse gases – these are used as refrigerants instead of CFCs (chlorofluorocarbons) and HCFCs (hydrochlorofluorocarbons) which are known to cause ozone depletion.

While F-gases may not deplete ozone, they are greenhouse gases with extremely high global warming potential with some several thousand times more potent then CO₂. An F-gas called fluoroform has a global warming potential of 14,800. This means that when fluoroform is released into the atmosphere, it will trap 14,800 times more heat for an equivalent amount of CO₂.

TFA is highly persistent so it resists most forms of physical, chemical and biological degradation. TFA is also highly mobile so it can enter waterways and move around them easily, while remaining in the environment for hundreds of years. This is why it’s now accumulating and cropping up in our environment more often, contaminating our rivers, food and even our wine.

Scientists have analysed levels of a particular forever chemical in 32 UK rivers.

TFA has been found in rivers across the globe including the US, China, Germany and Switzerland. These findings have triggered joint research between environmental charity Fidra and scientists at the University of York to sample water from and analyse the TFA levels in 32 UK rivers, streams and lakes. They found TFA present in 31 of the 32 sites investigated, including an exceptionally high level in the River Kelvin, Glasgow (the second highest recorded globally to date). This is approaching levels where TFA has been previously observed to start having adverse effects on aquatic organisms.

The trouble with TFA

Apart from its major source being as a breakdown product from the production of greenhouse gases (and knock on climate change effects), the presence of TFA in our environment represents a genuine threat to human and environmental health.

Currently there is no guidance for safe levels of TFA in drinking water, and it is not something that is measured. However, if it is present in our rivers and lakes, then there is a potential pathway for it to enter our drinking water. This needs to be addressed so that our levels of exposure, and the level of threat that TFA poses, can be assessed by scientists, industries and regulators.

While evidence is limited on human toxicity of TFA, studies dating back more than 25 years have highlighted its potential effects on aquatic organisms, including effects on development of zebrafish, as well as various algaes, which act as important food sources in aquatic ecosystems. Studies on mammals have that continuous TFA exposure could lead to shown increased liver sizes (suggesting the possibility of a significant underlying, unknown medical condition) and potential disruption to reproductive hormones, causing fertility and foetal development issues.

The EU’s chemical regulator, the European Chemicals Agency is responsible for ensuring chemical safety in Europe. They suggest TFA poses a low threat if exposure is short term. However, longer-term exposure effects remain unknown. With other PFAS, recommended weekly maximum intakes have been substantially reduced as knowledge has advanced.

While TFA pollution continues unabated, levels in the environment beyond those 32 rivers – and in our food and drink – remain difficult to quantify. It is also hard to confidently suggest methods to reduce personal TFA exposure. However, work by myself and colleagues has shown that exposure to many PFAS can be reduced by filtering tap water with activated carbon or charcoal filters. Other researchers have suggested that this could be an effective way to remove TFA from drinking water, as long as filters are changed regularly.

Johnny Depp’s new film about Modigliani is in danger of downplaying his importance as an artist – an art expert’s verdict

Source: The Conversation – UK – By Frances Fowle, Personal Chair of Nineteenth-Century Art, History of Art, University of Edinburgh

In 2018 an oil painting of a nude by the Italian artist Amedeo Modigliani broke a world record when it sold at Sotheby’s for US$157.2 million (£115.2m). It was created in 1917, at a time when Modigliani was unable to sell his pictures for more than a few francs.

Johnny Depp’s new film Modi: Three Days on the Wings of Madness explores the artist’s struggle to sell his work, and the tension that existed between his own idealism and the need to be commercially minded.

The film also addresses Modigliani’s mental instability, brought on by self-medication while suffering from tuberculosis. He took refuge in hashish and alcohol (including absinthe), and this movie pulls out all the stops when it comes to visualising the horrors and hallucinations that afflicted him as the illness progressed and the drugs took hold.

Set against the background of Paris during the first world war, the action takes place over three days in 1916. It takes its inspiration from Modigliani – A Play in Three Acts by Dennis McIntyre and remains remarkably faithful to the plot.

This revolves round Modigliani’s friendship with the artists Chaïm Soutine (Ryan McParland) and Maurice Utrillo (Bruno Gouery); his tempestuous relationship with the English poet and writer Beatrice Hastings (Antonia Desplat); and his reliance on the art dealer Léopold Zborowski (Stephen Graham). It is Zborowski who sets up a much-anticipated meeting with an important collector, Maurice Gangnat (Al Pacino).

Modigliani, brilliantly and energetically portrayed by Riccardo Scamarcio, comes across as a passionate, idealistic and irresistible genius. However, he is also haunted by ghosts, and a slave to his drug addiction, perhaps echoing Depp’s own past.

Depp’s film – his second as director – never loses pace. In one scene Modigliani plunges through a stained-glass window. In another he shocks potential buyers by setting fire to a painting; in a third he trashes his studio, destroys his most recent sculptures and slashes several canvases.

The title of the film, Modì, was the artist’s nickname, but is also a play on the French word maudit, meaning cursed. As a young man Modigliani was an avid reader of the German philosopher Nietzsche, whose own descent into madness was punctuated by periods of lucidity.

Nietzsche saw no clear distinction between dreaming and waking, and the film reflects this in the way in which hallucination, memory and reality become confused. Modí masks his increasing pain with alcohol, drinking with his artist friends Utrillo and Soutine in the seedy Bateau Lavoir in Montmartre.

Of Belarusian extraction, Soutine, like Modigliani, was a Jewish outsider. In 1916 the two artists occupied neighbouring studios in La Ruche, a down-at-heel artists’ residence in the 15th arrondissement of Paris. Before he achieved commercial success, Soutine lived in abject poverty, forced to sleep rough in stairways and on park benches. He suffered from depression and anxiety, and his internal turmoil is reflected in his highly expressive work.

The third member of the triumvirate, Maurice Utrillo, also suffered from mental health issues, and took up art to ward off depression. The movie alludes to this as the reason he was unable to enlist during the war. Instead, he spent regular periods in hospitals and mental institutions and painted many of his views of Paris from postcard images.

Modigliani, too, tried to join up, but was refused due to poor health. In the film this memory sparks an episode of disturbing hallucinations, featuring walking wounded with horrific injuries, and a plague doctor doubling as a spectre of death, a leitmotif for Modigliani’s own fear of dying.

Following such nightmarish episodes, Modigliani turns to Beatrice Hastings, who adopts the role of carer (and, as the film implies, substitute mother) as well as lover. She was however, motivated as much by Modigliani’s genius, as by her own burgeoning career as a poet, literary critic and co-editor of the British avant-garde magazine The New Age.

In the film she is frustrated by Modigliani’s idealism. She encourages him to be more pragmatic and commercially minded and berates him, not for embracing life, but for constantly “running from death”.

She is also the artist’s muse, the model for his “masterpiece”, a reclining nude, and an unfinished sculpted head of a woman. Both are cinematic devices; there is no evidence that Beatrice ever posed nude, while the sculpted head was produced in 1911-12, before the two had even met. Despite this, both works play a central role in the film’s denouement, sparking the artist’s falling out with Zborowski.

The climax of the movie is the artist’s much-anticipated meeting with Gangnat, a rich industrialist and significant figure in art history, whose collection included 160 works by Auguste Renoir. The meeting, predictably, is a disaster, but, even though he leaves without a penny, Modigliani has the last word: “I am much richer than you, Monsieur Gangnat,” he insists, “You have merely existed…I have lived”.

Was Modigliani as idealistic as the film portrays? Possibly, but perhaps not, for by 1916 he had already met a new and influential dealer, Paul Guillaume, who would ensure a commercially successful future, not only for our hero, but also for Soutine and Utrillo.

In the end, the film is an enjoyable romp, even if it is in danger of downplaying Modigliani’s importance as an artist in favour of the more sensational aspects of his life.

And yet it is undeniable that his life really did read like a film script. He died of tuberculosis in January 1920 at the age of 35. Two days later his common-law wife, Jeanne Hébuterne, pregnant with their second child, took her own life. Soon after, however, thanks to dealers such as Zborowski and Guillaume, the importance of Modigliani’s work was finally recognised, and today he is remembered as one of the most significant artists of his generation.

What would it take for a new British left-wing party to succeed?

Source: The Conversation – UK – By Colm Murphy, Lecturer in British Politics, Queen Mary University of London

Last week, the MP for Coventry South, Zarah Sultana, made an audacious decision. Having already lost the Labour party whip for opposing the two-child benefit cap, Sultana announced she would co-lead a new left-wing party with Jeremy Corbyn, who was expelled from Labour in 2024.

From one angle, her decision may seem simple. Discontent with Keir Starmer’s Labour government, on everything from welfare cuts to Gaza, has never been higher, and Sultana is a vocal critic. Yet, launching a (still unnamed) new party is bold. It tackles head-on an old and vexing question for socialist critics of capitalism in the UK.

In 1976, the socialist theorist Ralph Miliband (yes, Ed and David’s dad) described the faith in Labour’s capacity to become a socialist vehicle as “the most crippling of all illusions”. But socialists who agree with Miliband senior then have an almighty problem.

Writing months after the 2019 defeat of Corbyn’s Labour party, the veteran “New Left” academics Colin Leys and Leo Panitch echoed Miliband in their book Searching for Socialism. But they also saw few immediate alternatives with “any prospect of electoral success”. This, they wrote, is the “central dilemma” for British democratic socialists.

The reaction to Sultana’s announcement from the British left has been accordingly mixed. Leaks revealed that Corbyn’s team was caught off guard. Responses from prominent potential supporters were reserved. Momentum, the left-wing grassroots organisation, hastily distributed the pamphlet Why Socialists Should Be in the Labour Party.

It’s too early to know whether these issues are teething problems or portents. But the barriers to Sultana’s venture are formidable. What would it take for a new left-wing party to succeed? What would “success” even look like?

A careful reading of political history can help us answer these questions. This is not the first time that new parties have emerged from Labour factionalism. Many readers will be aware of the 1981 departure of the “gang of four” Labour figures, who founded the Social Democratic party (SDP) that later merged with the Liberal party to form the Liberal Democrats.

Nor is it the first time that smaller parties have appeared on Labour’s left. Between 1920 and 1991, the Communist party of Great Britain was a potent force in the trade union movement. From the 1990s to the 2010s, several vehicles contested local and national elections against Labour, from the Socialist Alliance to Left Unity.

Challenges for a new party

Each of these iterations had its historical peculiarities. But stepping back, we can identify three recurring challenges that any left-wing insurgent party must confront.

First, they must agree on an electoral strategy and purpose, given the institutional brutality of British democracy. The UK has some proportional elections, including in Scotland and Wales (expected to be next contested in 2026). Councils are also possible avenues of influence.

But there is no avoiding the fact that legislative and executive power is hoarded in the House of Commons, elected by first past the post. Labour will discourage possible defectors by warning that a split in the left vote will let in the right. Neil Kinnock, Labour’s former leader who found himself fighting off the SDP while trying to evict Thatcher in the 1980s, dubbed Sultana and Corbyn’s venture the “Farage assistance party”.

Left of Labour parties are often aware of the risk. Indeed, far left activists have in the past advocated voting Labour, with “varying degrees of (un)enthusiasm”.

Advocates of a new party will note that Labour is only polling in the low 20s, suggesting a pool of ex-Labour voters potentially interested in shopping around. However, there are others it could torpedo too.

One recent poll on support for a hypothetical Corbyn-led party – which we should take with some salt – found that its 10% support comes partly from eating into the Green vote. An electoral arrangement with the Greens, on the other hand, may require shared policy platforms, raising the question of why a separate party is needed.

A poll from More in Common conducted specifically about a Sultana-Corbyn party found 9% of Labour voters and 26% of current Green voters saying that would vote for such a party.

The Socialist Labour party (SLP) – founded in 1996 by the prominent trade unionist Arthur Scargill in reaction to Tony Blair’s New Labour – is the obvious cautionary tale. Scargill wanted a purer, better Labour party. Yet, Labour looked set to kick out an 18-year-long Conservative government.

Scargill could not convince many sympathetic activists to join. As historian Alfie Steer argues, the SLP instead became dominated by socialists hostile to the Labour party. The party could not overcome the resultant contradictions in its purpose and collapsed into acrimony.

The SLP also illustrates the second key consideration: timing. The SLP struggled partly because it launched just as Labour was sweeping triumphantly into power. Sultana’s timing is arguably more astute. She has waited for Starmer’s bubble to burst and for disillusionment to fester.

However, the broad left within Labour has also just found its voice by rebelling against government policy. The temptation for a risk-averse Labour activist may be to leap onto this critical bandwagon without taking the more dangerous step of defecting.

The final challenge is securing institutional durability without debilitating splits. It is telling that Sultana felt compelled to include Corbyn’s name despite his reported reservations.

Sultana herself has an impressive political profile, especially on TikTok. Any new party will rely heavily on prominent spokespeople to force it into the national conversation. Yet, such vehicles can become trapped by their dependence on individuals. The Respect party of the 2000s, for example, was reliant on the charismatic but polarising figure of George Galloway.

The fledgling party will also need a lasting structure that determines how candidates are selected and policy is formed. This risks dragging it into dreaded constitutional debates. It is already reportedly divided over the existence of co-leaders.

Intra-party democracy is off-putting to outsiders. But as constitutional scholar Meg Russell argues, it speaks to fundamental questions about the extent, and limits, of democracy. Such disputes have frequently wracked the left (and the radical right, as Reform’s recent constitutional changes show).

To what extent should policy be “democratically” decided? Should a new party limit who can join, and if so, on what criteria? How will leaders be selected? From the CPGB to the SLP, these questions have proven divisive in the past. They could easily prove so again.

The new party faces severe challenges, but it would be unwise to write it off completely. In a volatile context, it has a chance to make its mark if it is clear in its strategic electoral purpose, cultivates an institutional and activist base and times its interventions astutely. But the obstacles to success are enormous – and with Reform currently polling top, the risks are high.

My artwork, A Virtuous Woman, has become the centre of a protest – it shows how our polarised society can affect art

Source: The Conversation – UK – By Layla Khoo, PhD Candidate, Public Participatory Contemporary Art, University of Leeds

My project A Virtuous Woman is both an artwork and a piece of ongoing research into the role of participatory artwork in heritage sites. As such, the artwork was always intended to be dynamic, responding to the ways in which people wanted to take part.

The artwork was inspired by the embroideries of the ancient noble women commissioned by one of the most notable women in Elizabethan court and society, Bess of Hardwick, four of which are on display at the National Trust property, Hardwick Hall. The new work was intended to be a reimagining of the missing fifth embroidery, made from recycled fabrics donated by the National Trust staff and volunteers.

Visitors to the hall could take part in sewing, cutting and adding their own expressions through embroidery. But after two participants added the name of author J.K. Rowling to the piece and another embroidered a line of stitches through both instances, things became complicated.

A protest was staged at Hardwick Hall and the artwork became the centre of a media storm. I have been subject to accusations and abuse online for displaying the work complete with these conflicting pieces of participation and the National Trust have received a barrage of complaints. So where does this leave participatory arts, the artists who create and facilitate them and the sites which commission and host them?

Participatory arts have to consider not only the freedom of expression of the artist, but of every person who participates. Both the National Trust and I had to attempt to balance the expressions of participants in a political polarised climate, while witnessing a media fallout when groups and individuals disagree with the choices made.

Participation with the artwork took place between April and November 2024. Throughout this time, the work prompted discussion and debate around the subject of virtues and the women that visitors felt upheld these values.

Thousands of people added their embroideries. In total 186 words of virtue or value, and 804 names were added to the piece. Some were embroidered by more than one person (a few stitches, or a letter each), some participants embroidered more than one contribution, and many virtues and names were repeated multiple times.

The Hardwick Hall team and I had previously agreed that no names would be censored or removed from the work, and that participants would not be allowed to unpick each other’s embroidery. However, while not encouraged, participants would be allowed to interact with and adapt the embroidery of other participants.

In August 2024, a complaint was raised after two people added Rowling’s name to the piece. The author has sparked controversy in the last few years as a result of her “gender critical” views, which many see as transphobic (a claim which Rowling denies), while others see her as a figurehead for women’s rights. A participant then embroidered a line of stitches through both instances of the name on two separate panels (in the colours of the trans pride flag), while leaving the name clearly visible.

We now needed to consider whether staff, volunteers and visitors might feel offended, unsafe or unwelcome when encountering the recognition of a person seen by some as harmful. We also needed to think about the dismissal of someone admired by others for their cultural influence and beliefs.

At the request of the National Trust, the project was “paused” for a month while advice was taken on the most appropriate way forward. Staff were prepared through workshops run by the National Trust team on how to deal with potentially difficult interactions with participants.

I was asked by the National Trust team if I was willing to remove any embroidered names from the work, including repetitions. I said I was not, as participants had taken part in good faith and were expecting to see their contribution in the completed work.

The Hardwick Hall team and I agreed that all names would remain, and all subsequent names added would not be subject to censorship. We agreed that the lines stitched through Rowling’s name would also remain. I felt that removing them would remove an act of protest – a valid act of participation – and that leaving it on display would demonstrate the difficulties and friction involved in creative expression and participation in our often-polarised society.

Many participants saw Rowling’s crossed out name while embroidery was still taking place, and some responded by adding her name again. Participants discussed cancel culture, polarised views and the complexity of the people they admire.

When the artwork was complete, Rowling’s name appeared seven times – twice with a line stitched through, five times unaltered. The completed artwork was placed on display at Hardwick Hall in January this year.

On May 24, the Women’s Rights Network (WRN) posted a thread on X detailing a visitor complaint regarding the crossing out of Rowling’s name. They called for the National Trust to add a statement to the artwork, explaining why the crossing out remains on display. Members of the WRN subsequently carried out a protest on site and created a short film explaining their position.

On May 31, two visitors to Hardwick Hall cut away the line of stitches and posted images and video of themselves doing so on X.

The subsequent mainstream media coverage, blog posts and widespread social media attention resulted in threats of further activism.

The National Trust initially covered the work to protect it, but then removed it from display on June 4, as there was now also a risk to other artworks and collection items at Hardwick Hall, and to the staff and volunteers on site.

The National Trust released a statement on X, which appeared to do little to answer questions being raised. There are now growing calls for commentary from me, as the artist responsible for the work, to explain what has happened, how decisions were made and where I stand both on the actions taken and the wider gender debate this speaks to.

Limitations in creative expression

I believe that the arts are in a unique position to tackle difficult subjects, and participatory arts can provide an opportunity for more voices to be heard. But with this approach comes the inevitable balancing act of where freedom of expression ends and causing harm begins.

Consideration must be given to intention versus impact. Making these editorial and ethical choices creates a changing power dynamic. The participants have been invited to take part and do so in a way that is meaningful to them in what they believe to be the overall context of the work.

In participatory arts, the artist is part author, part facilitator of the expressions of others. The commissioning body or hosting site then holds the ultimate control, in being able to choose whether to display the work created.

My part in the decision to allow the stitching through of Rowling’s name essentially comes from a shared belief in singer Nina Simone’s view that “an artist’s duty … is to reflect the times”.

In my opinion, the acts of protest and activism in the crossing out of the name and the removal of that crossing out epitomise the lack of tolerance for other people’s views and beliefs that is becoming prevalent in our increasingly polarised society. As such, I think it is entirely appropriate to display these actions in the artwork. This polarisation and intolerance has been compounded in the subsequent outpouring of online vitriol and demands for what this work should and should not represent.

Both acts of activism changed the artwork, and disregarded the previous participant’s contribution. The difference is that the crossing out took place while participation was invited and expected – the removal of that crossing out was not. As the artist responsible for the artwork I have faced increasing demands not just to clarify the events leading to this point, but also to openly share my views on the actions taken by all parties. However, an artist sharing their opinion is not simple, or necessarily safe.

In its recent report, Freedom of Expression in the Arts (a five-year project aiming to tackle the culture of fear and intimidation some artists face for expressing their views) found that artists are increasingly afraid to express themselves on dangerous topics for fear of backlash from the public and cancellation of work opportunities by commissioning bodies.

My own experience has shown that social media is neither the place for nuanced, balanced, nor reasonable debate. I have been accused of transphobia for allowing the inclusion of Rowling’s name in the first place, and called (among other things) a “gender traitor” for allowing her name to be crossed out. But when a commissioning body or host site cancels a work which speaks to these debates, how else are artists able to speak out?

In a comment sent to The Conversation, a National Trust spokesperson said: “A Virtuous Woman is formed of people’s views from a variety of age groups, life experiences and beliefs … We understand that everyone may not agree on all the names included, but they are the choices of individual participants. Everyone is welcome at the National Trust, and the artwork reflects the diversity of the community and individuals we serve. Our approach is to make space for a variety of creative and personal responses to the collections and to encourage conversation.”

At the time of writing, I have been told that the redisplay of a projection of the artwork and explanatory panels is under review and is unlikely to take place until September 2025. Participatory arts hold up a mirror first to those who take part, and then again in the reception and judgement of subsequent viewers. The difficulty comes when we don’t like what it reflects.

Why Trump blames decisions on others – a psychologist explains

Source: The Conversation – UK – By Geoff Beattie, Professor of Psychology, Edge Hill University

It was US president Harry S. Truman who, in the years just after the second world war, kept a little wooden sign on his desk which read: “The buck stops here!”. It emphasised his willingness to accept ultimate responsibility for his decisions and actions as president, even the ones that didn’t quite work out.

This phrase has since become emblematic of presidential accountability and leadership. Truman wasn’t interested in trying to pass the buck, not as a man and certainly not as president.

Interestingly, the sign was made in the Federal Reformatory (prison) at El Reno, Oklahoma, suggesting an implicit moral dimension to this issue of responsibility and accountability. We’re all accountable for our actions, whoever we are, but the president above all.

But how things seem to have changed with Donald Trump in the White House.

Trump continually takes personal credit for any perceived successes as president – fixing global tariffs, Nato members paying more, the Middle East (even taking credit for things that were completed before he took office). But he makes sure that any failures are immediately attributed elsewhere.

He frequently positions himself as surprised or “blindsided” by unpopular decisions, which are always somebody else’s doing, somebody else’s fault. Subordinates are held responsible. He is not averse to pointing the finger directly at them, and often in public, high-profile settings.

That great loyal Trump supporter, defense secretary Pete Hegseth, for example, has recently been in the firing line for being personally responsible for pausing the delivery of missile shipments to Ukraine. US defence officials had apparently become concerned that weapons stockpiles were becoming low, as they needed to divert arms to Israel to help in the war with Iran.

But the pause in supplying some weapons to Ukraine announced by the Pentagon on July 2 was a hugely unpopular decision that resonated around the world. Hegseth was blamed.

Some have suggested that having loyalists such as Hegseth in critical positions like secretary of defense is highly strategic, and not just for the more obvious reasons. You could argue that having loyal supporters with delegated but overlapping authority is highly advantageous when it comes to the blame game.

Trump can publicly distance himself when things go wrong (as he did here), claim a degree of surprise, and swiftly change course. That way he is publicly reasserting his role as leader without admitting fault.

It is also noteworthy that Trump often reverses these decisions made by his subordinates in high-visibility environments, which suggests a determined pattern of strategic image management.

It’s a simple set of moves – you allow a subordinate to initiate a controversial decision, then you rein it in publicly and reassert your authority, thus showcasing your resolve. In other words, delegation to loyal insiders like Hegseth becomes a useful buffer against political fallout.

Loyal insiders still stay loyal (for the foreseeable future at least). They won’t sling mud, like some might in their position. So Trump can appear masterful.

Are you going to send weapons to Ukraine? President Trump reverses a policy and decides he will.

But of course, there’s more to this than everyday political shenanigans. Personality plays a major role. Some psychologists have argued that not internalising failure is psychologically beneficial.

If you take credit for success but externalise failure, that makes you resilient (and happy). But there are clearly limits to this, and there’s a darker side.

People with high levels of narcissism (“I like to be the centre of attention”; “I am an extraordinary person” – both items on the narcissism personality inventory, a method of measuring personalities) often avoid accountability because they perceive themselves as superior to others. But only, it should be noted, in certain “key” aspects of life.

In the words of Jean Twenge and W. Keith Campbell, authors of The Narcissism Epidemic: “Narcissists think that they are smarter, better looking and more important than others, but not necessarily more moral, more caring or more compassionate.”

Narcissistic individuals tend to externalise blame to protect their fragile self-esteem and maintain their self-image. They may refuse to admit fault because doing so threatens their grandiose concept of self.

Individuals exhibiting Machiavellian traits, characterised by manipulativeness and a lack of empathy, are also more prone to shifting blame. They may deflect responsibility to serve their self-interest, which is clearly a highly manipulative manoeuvre. You just do whatever is required.

Research also indicates that individuals with low conscientiousness, one of what are considered the “big five” personality traits, are less likely to accept responsibility for their actions. They may be somewhat careless or irresponsible in their work or actions, and when mistakes do occur – which they will – they blame external factors or other people.

In other words, certain personality traits are associated with a tendency to avoid accountability and responsibility.

It has been said that Trump’s inner circle consists of loyal sycophants who, even when it’s cringeworthy for outsiders, publicly praise him to amplify and protect his self-image. He needs this from them.

But they have another use as well. When things don’t go so well, they take it on the chin for him. That’s almost part of the job description. When things go wrong, his inner circle all understand the buck really stops with them.

Raison d’être : une nouvelle arme stratégique pour les conseils d’administration européens ?

Source: The Conversation – in French – By Rodolphe Durand, Professeur, stratégie et Politique d’Entreprise, HEC Paris Business School

Comme des centaines de grandes entreprises européennes, le groupe Véolia s’est doté d’une raison d’être. Shutterstock

Une étude menée auprès de 21 très grandes entreprises européennes comme Accor, Barclays, Decathlon, Enel, L’Oréal, Michelin, Philips ou RTL Group, révèle une approche nuancée du corporate purpose par les conseils d’administration des entreprises européennes interrogées. Quatre approches se dégagent: la raison d’être comme slogan, guide, style et boussole, chacune avec ses avantages.


Le 24 avril dernier, l’assemblée générale de Veolia a voté à plus de 99 % l’inscription de la raison d’être dans les statuts de la société. Ce qui veut dire que le conseil d’administration de Veolia plus encore qu’avant devra suivre la mise en œuvre de sa raison d’être par la direction générale de l’entreprise. Quelle sera son approche ?

Dans cet article, plutôt qu’une fois encore se poser la question du management de la raison d’être de l’entreprise (ou corporate purpose) par la direction de l’entreprise, nous nous demandons comment les conseils d’administration des grandes entreprises européennes orchestrent… leur administration. Pour rappel, le conseil d’administration organise les pouvoirs de décision, définit la stratégie de la société, et s’assure de sa mise en œuvre.

La récente étude menée par HEC Paris et Oxford University auprès de 21 très grandes entreprises européennes comme Accor, Barclays, Decathlon, Enel, L’Oréal, Michelin, Philips ou RTL Group, révèle une approche nuancée du corporate purpose par les conseils d’administration des entreprises européennes interrogées . Elle révèle une vision de la raison d’être comme un principe organisateur qui structure la prise de décision, définit les activités et contours identitaires de l’entreprise.

En Europe, au sein des conseils d’administration, quatre approches existent, que nous avons appelé: slogan, guide, style et boussole, chacune avec ses avantages et ses inconvénients. Le maître mot ? Ajuster l’approche de la raison d’être par le conseil d’administration avec les objectifs et les moyens donnés à la direction générale et au management pour sa bonne mise en œuvre.

Quatre approches de la raison d’être

Notre étude identifie ces quatre approches au niveau des conseils d’administration des grandes entreprises européennes. L’approche change selon deux dimensions : si le conseil, et ses comités associés se réfèrent à la raison d’être de façon implicite ou explicite et si les mesures, valeurs et comportements associés à la raison d’être sont abordés de façon générale – abstraite – ou précise – détaillée.

Types de mode d’administration de la raison d’être au sein des conseils des grandes entreprises européennes. Motto signifiant slogan.
Fourni par l’auteur

L’une des conclusions les plus frappantes concerne l’importance cruciale de l’alignement entre l’orchestration au niveau du conseil et la mise en œuvre opérationnelle par le management. Les entreprises qui échouent à synchroniser ces deux niveaux risquent de dysfonctionner. Soit elles engagent trop de ressources, alors que leur mode d’administration ne le requiert pas. Soit elles engagent trop peu de ressources, alors que leur mode d’administration l’exigerait.

Le défi principal ne réside pas tant dans la formulation du corporate purpose, que dans sa traduction opérationnelle au sein des conseils d’administration, à l’interface des représentants des actionnaires – les administrateurs – et de ceux qui agissent pour le développement de l’entreprise – les managers.

Slogan : l’agilité au prix de la cohésion ?

L’approche « Slogan », implicite et abstraite, est la version la plus libre et fluide des quatre approches. Dans cette celle-ci, la raison d’être demeure implicite, car elle n’est pas inscrite dans des pratiques formalisées. Elle est invoquée sous forme de rappel lors de certaines décisions, sans processus formel au sein des comités. Prenons l’exemple d’une des entreprises interrogées.

« La raison d’être est partie intégrante de qui nous sommes et alimente la prise de décision, tant au sein du conseil qu’à l’intérieur de l’entreprise ». rappelle la présidence d’un comité interviewé

Cette approche permet une grande agilité, sans brider la capacité à innover rapidement. En laissant aux équipes de management la liberté d’interpréter la raison d’être selon leur contexte culturel et concurrentiel, elle autorise une forte résonance locale à la raison d’être. Elle séduit particulièrement les entreprises opérant dans des environnements complexes ou multiculturels. Cette flexibilité peut toutefois virer à la dispersion. Lorsque chaque filiale ou business unit s’approprie à sa manière les valeurs et la finalité de la raison d’être de l’entreprise, le risque existe de perdre la cohésion d’ensemble. Le sens commun s’effiloche, et avec lui, l’alignement stratégique.

Style : les valeurs comme moteur, au risque de l’ambiguïté ?

L’approche « Style » correspond à une compréhension implicite de la raison d’être par le corps social de l’entreprise corrélée à un suivi par le conseil d’un certain nombre d’indicateurs. Cette approche valorise la confiance et l’autonomie des dirigeants dans les propositions stratégiques qu’ils soumettent au conseil. En retour, le conseil suit des indicateurs d’engagement des salariés, de cohérence des valeurs dans les décisions, notamment au sein de comités spécifiques traitant de la stratégie ou de la rémunération des dirigeants.

Pour le management, le caractère implicite permet de s’appuyer sur la force de cultures professionnelles. Le suivi détaillé d’indicateurs fournit des appuis pour décliner des pratiques managériales au sein des unités opérationnelles. Comme pour l’approche « slogan », l’absence de cadre explicite peut générer des interprétations ambiguës de la raison d’être et mener à des incohérences. Chacun y projette son propre sens, au risque de créer de la confusion stratégique. Si des mécanismes de suivi trop lourds sont mis en place, cette approche se retrouve piégée dans une logique d’exécution… plus que d’inspiration.

Guide : des principes affichés, mais pas infaillibles ?

L’approche « Guide » rend explicites les valeurs de la raison d’être sans pour autant imposer un suivi détaillé d’indicateurs par le conseil d’administration. Ce mode d’orchestration renforce la coordination entre les équipes, installe une culture d’entreprise partagée par le plus grand nombre, ce qui favorise l’engagement des collaborateurs. Le conseil peut mobiliser la raison d’être au sein de comités, notamment le comité stratégique au sujet des cessions et des acquisitions. La raison d’être sert de guide informel pour orienter le management dans ses plans de développement de l’entreprise.

La « raison d’être » de l’entreprise rebat les cartes du jeu concurrentiel


Du point de vue de la direction générale, cette approche peut s’avérer difficile à suivre en l’absence de critères détaillés. La culture forte de l’entreprise peut, avec le temps, devenir une fin en soi, voire réduire la raison d’être à un symbole plutôt qu’un véritable moteur stratégique. En période de crise, en l’absence d’indicateurs suivis précisément par les comités du conseil, le « guide » peut être oublié pour se tourner vers les solutions plus immédiatement lucratives. Et le management pourrait prendre des décisions déconnectées de la raison d’être initiale, semant les graines de dilemmes futurs.

Boussole : aligner mais sans étouffer

Le modèle « Boussole » combine une explicitation de la raison d’être avec un suivi détaillé de nombreux indicateurs. Dans cette configuration, l’espace de jeu entre le conseil et le management est réduit : ils sont conjointement tenus responsables de la réalisation de la raison d’être.

« Les chiffres des budgets vus en conseil reflètent de façon précise et détaillée l’application factuelle de la raison d’être et le développement à long terme des projets qui viennent la soutenir », confie un président de conseil d’administration

Une autre présidente souligne que l’ensemble des comités (y compris celui sur les risques) se réfèrent explicitement à la raison d’être et aux indicateurs pour porter ses analyses. Cette approche crée une forte mobilisation, des comportements alignés et une cohérence globale. Cette rigueur a un prix. La mesure et le reporting de la raison d’être peuvent devenir complexes, voire paralysants selon certains dirigeants. Lorsque les résultats ne sont pas à la hauteur des attentes élevées, le risque est de susciter incompréhensions, frustrations, voire désenchantement au sein de l’entreprise.

La raison d’être s’administre autant qu’elle se manage

L’avenir du corporate purpose en Europe ne se résume pas à une compliance réglementaire ou à une stratégie de communication. Non plus à un ensemble de pratiques managériales. Pour en retirer le meilleur, il s’agit de bien aligner les pratiques du conseil d’administration et les demandes et moyens alloués au top management pour mettre en œuvre la raison d’être. Quatre approches existent, chacune avec ses forces et ses faiblesses.

Nous pensons que cette conception européenne du corporate purpose, ancrée dans l’histoire du continent et tournée vers l’avenir, dépasse désormais la simple question du management. Elle concerne la définition, le rôle et les responsabilités des membres des conseils d’administration et plus généralement de la gouvernance des entreprises, au service d’une compétitivité repensée dans ses dimensions, sa finalité, et sa temporalité.

Rugby headgear can’t prevent concussion – but new materials could soften the blows over a career

Source: The Conversation – Global Perspectives – By Nick Draper, Professor of Sport and Exercise Science, University of Canterbury

The widely held view among rugby players, coaches and officials is that headgear can’t prevent concussion. If so, why wear it? It’s hot, it can block vision and hearing, and it can be uncomfortable.

Headgear was originally designed to protect players from cuts and abrasions. But players still hope it will offer them a degree of protection against the collisions they experience in the game. Some players adopt it after previous concussions.

We’re now seeing increasing numbers of professional players opting in. The Irish men’s team, for example, field up to five players each match sporting headgear. In Japan, it’s mandatory for juniors. And more parents in New Zealand are making their children wear it, too.

The exact specifications for rugby match kit – boots, shorts, shoulder pads and
headgear – are regulated through World Rugby’s Law 4 and Regulation 12. In 2019, the governing body launched a trial enabling players to wear headgear with new technical specifications in training and matches.

The specifications have meant manufacturers can take advantage of novel “isotropic” materials that can potentially reduce the impact forces experienced by players.

Conventional headgear is composed of soft foams that flatten when a player’s head collides with the ground or another player. As such, they can only minimally absorb those collision forces.

Isotropic materials behave differently. They can absorb impacts from multiple directions and may offer a level of protection against the effects on a player’s head of a tackle or other collision event.

Given these changes, and in light of recent research, we may need to change the narrative around rugby headgear: while it may not prevent concussion, it might reduce the total contact “burden” experienced by players in a game and over a whole season. And this could have benefits for long-term brain health.

Impacts across seasons and careers

Contact in rugby – through tackles, at the breakdown, and in scrums and lineouts – leads to players experiencing a number of collisions or “head acceleration events”. This contact is most commonly head to ground, head to body or head to head.

By having players use “smart” mouthguards with embedded micro-accelerometers and gyroscopes to capture head movements, researchers can now measure each collision and each player’s contact load in a game – and potentially over a career.

A player’s total contact load is found by adding together the magnitude of the impacts they experience in a game. These are measured as “peak linear accelerations” or “peak rotational accelerations”.

While past research and media attention has focused on concussion, it has become clear the total contact burden in training and matches – the total “sub-concussive knocks” through head acceleration events – may be as important, if not more so.

One of our own research projects involved following 40 under-16 players wearing smart mouthguards for all training and matches across one season. Peak Linear accelerations are measured as a g-force (g). Activities such as such as running, jumping and shaking the head would measure under 8g, for example, whereas heading a soccer ball might measure 31g.

The results of our study showed the players differed greatly in their cumulative exposure over a whole season, from 300g to nearly 14,000g. These differences would be amplified further over an entire rugby career.

Some of the variation is likely due to a player’s team position, with loose forwards having a greater burden than others. But it also seems some players just enjoy the contact aspects of the game more than others.

Potential benefits of new headgear materials

Researcher Helen Murray at the University of Auckland has highlighted the need for more research into the burden of collisions, rather than just concussions, over a rugby career. In particular, we need to know more about its effect on future brain health.

We hope to contribute to this by following our existing cohort of players through their careers. In the meantime, our research has examined the potential of existing rugby headgear and new isotropic materials to mitigate peak accelerations in rugby collisions.

Using the field data collected from male and female players over the past four seasons, we have designed laboratory testing protocols to compare the conventional and newer materials.

The results suggest the new forms of headgear do have the potential to reduce the impact burden for players.

We found 55–90% of head acceleration events do involve direct contact with the head. As such, collision-mitigation headgear could be beneficial. And our laboratory testing produced an estimated 30% reduction in peak linear accelerations with the headgear compared to without.

The nature of concussion is complex and related to the size of an impact as well as its direction and angle. For instance, we observed the concussions experienced by the junior players occurred between 12g and 62g – well below the male threshold of 70g requiring professional players to be removed from the field for a head injury assessment.

Currently, it seems unlikely headgear can prevent concussion. But it does appear new headgear materials could significantly reduce the total impact burden for players during their careers. And this may help safeguard their future brain health.

What is the Strait of Hormuz and why is it so important for global shipping?

Source: The Conversation – Global Perspectives – By Belinda Clarence, Law Lecturer, RMIT University

During the recent conflict between Iran and Israel, Iran threatened to block the Strait of Hormuz, one of the world’s major shipping routes.

Would that be possible, and what effects would it have?

The Strait of Hormuz is a choke point at the entrance to the Persian Gulf. It is used to transport about 20% of global daily oil consumption.

Iran effectively controls this crucial shipping route because it is a coastal state bordering this narrow stretch of water. The strait is too narrow to avoid navigating waters claimed by Iran. This raises thorny legal questions about whether it is really possible for Iran to block the strait, and what recourse other states have if it does.

This geographical reality is far from new, and the legal frameworks governing international maritime activity have developed over centuries. At its heart is the lex mercatoria — the “law of merchants” — a body of transnational commercial law that emerged organically from the practices of traders operating across borders.

Within this broader framework sits the lex maritima, or customary maritime law, which has long adapted to the hazards of shipping across vast oceans.

The lex maritima originated from the shared practices of seafarers and merchants. Its purpose? To manage the unpredictable nature of maritime trade that demands coherent and stable rules.

One of the most enduring principles of this legal tradition is the idea of mare liberum, or “the free sea”, set out by Dutch jurist Hugo Grotius in 1609. He argued the high seas should remain open to all for peaceful navigation and trade. This conveniently legitimised the ambitions of European colonial powers, granting them unfettered access to global maritime routes at a time when control over sea-based trade promised immense economic and strategic advantage.

The shifting boundaries of maritime law

One of the most fundamental questions in maritime law is: where do a nation’s territorial waters end, and the high seas begin?

After the second world war, a series of conferences culminated in the United Nations Convention on the Law of the Sea (UNCLOS), where the customary 3 nautical miles (5.56km) of territorial waters states could claim as their own was extended. This narrow limit was rooted more in historical naval range – the so-called “cannon shot rule” – than in modern geopolitical or environmental realities.

In 1959, Iran took the unusual step of unilaterally extending its territorial sea to 12 nautical miles, despite not being a party to UNCLOS. Two decades later, following the 1979 Iranian Revolution and the US Embassy hostage crisis, Washington grew increasingly anxious about the security of oil flows from the Persian Gulf. These concerns intensified during the Iran-Iraq War, especially as Iran began using small islands in the Strait of Hormuz to deploy military forces and threaten commercial shipping.

UNCLOS and the new rules of the sea

One of the key compromises of UNCLOS was an extension of territorial waters for states that ratified the treaty. In exchange, UNCLOS replaced the older concept of “innocent passage” – which allowed only surface navigation through territorial seas – with the broader notion of “transit passage”. Under this regime, vessels and aircraft from other states are granted the right to travel not only on the surface, but also under the sea and through the air above straits used for international navigation.

While 169 states have ratified UNCLOS, both Iran and the United States remain notable holdouts. This means Iran does not enjoy the broader 12-nautical-mile limit recognised under UNCLOS, and the US cannot claim the agreement’s protections for transit passage through strategic choke points.

While the geopolitical and legal tensions surrounding the Strait of Hormuz may seem far removed from the world of private commerce, the global economy continues to function thanks to a powerful legal tool: the contract. Contracts offer a predictable framework that allows trade across borders without parties needing to trust one another personally.

The Strait of Hormuz is bordered by active, assertive states such as Iran, which means the potential for interstate conflict is relatively high. This doesn’t mean commercial contracts are irrelevant to the recent dispute in the Strait of Hormuz — far from it. But their influence is more indirect.

What can be learned?

Without significant political change in Tehran, it’s unlikely either Iran or the US will shift its position on adopting UNCLOS. Yet despite Iran’s repeated threats to close the strait, it has never followed through — and the US Navy continues to maintain a steady presence in the region. For now, a fragile but persistent equilibrium holds.
