I wrote an unpublished essay about this subject – which I call ‘Cultural Heritage Diplomacy’, about three years ago.

At the private preview and unveiling of the Bayeux Tapestry at the British Museum on 2 September 2026, the leaders used the historic loan to champion a diplomatic and cultural ‘reset’ between the UK and France.

Speaking in both English and French, King Charles called the loan the ‘best possible symbol’ of the Entente amicale and a ‘precious symbol of trust’ demonstrating ‘what our countries can do if they join forces.’

President Emmanuel Macron described the tapestry as an epic that ‘bound our cultures, our histories and our destinies together,’ helping the nations to forge a bond as close as the embroidery’s threads.

Prime Minister Andy Burnham hailed the loan as a ‘landmark moment’ and a sign of closer bilateral relations in his first major European meeting.

George Osborne (Chair of the British Museum) noted the exhibition required negotiating across three different UK prime ministers. He described it as a ‘once in a generation’ partnership on par with Tutankhamun and Terracotta Warriors displays.

So, my Q. – which I examined in my essay, is whether Cultural Heritage Diplomacy’ is potentially a Mediation Tool for bringing about a lasting peace between states involved directly/indirectly in an armed conflict?’

I would emphatically answer the Q. in the affirmative – Yes!

This is not what my forthcoming book – the ‘Mediation of Cultural Heritage Disputes’ is about – see www.carlislam.co.uk, however based upon my essay, I will briefly state the arguments which support this thesis, and link them to a discussion of ‘Vatican Mediation’ – which is a fascinating hybrid form (the only example I am aware of), of ‘Institutional’ and ‘Ad Hoc’ Mediation. I wrote a post on LinkedIn about this earlier in the year.

‘Affirmative arguments’ are summarised in my comments below. However, these need to be balanced against counter-dynamic factors e.g. the ‘Sunken-Costs Fallacy’ – see my recent post about this and ‘Realism’.

So, how and when can Cultural Heritage Diplomacy’ (‘CHD’)provide an ‘off-ramp’ in an international armed conflict?

While CHD can rarely stop an active war on its own, it can act as a vital bridge to a lasting peace through specific mechanisms.

(i) ‘Overcoming the “Trust Deficit”‘ – In active or recent conflicts, direct political communication often breaks down due to an absolute lack of trust. CHD provides a neutral, non-threatening arena for hostile states to interact. As King Charles remarked during the unveiling, cultural exchange serves as a tool ‘at a time when trust seems sadly to be in short supply between nations.’ By sharing or protecting a physical piece of history, states can take low-risk, highly symbolic steps toward re-establishing baseline diplomatic goodwill.

(ii) ‘De-escalation Through Reciprocal “Soft Power”‘ – True Mediation requires mutual concession. The Franco-British agreement succeeded because it was a two-way cultural exchange. This reciprocity allows both sides to save face, project soft power, and demonstrate a mutual commitment to equality and respect.

(iii) ‘Re-writing a Shared Narrative’ – Wars are often sustained by rigid, nationalist histories that demonise the other side. CHD allows states to reconstruct a shared narrative. The Bayeux Tapestry depicts a violent Anglo-French war, yet President Macron noted at the exhibition that it ultimately represents a history that ‘bound our cultures, our histories, and our destinies together.’ When states look at a traumatic past through a joint cultural lens, it helps neutralise historical grievances that could fuel future conflicts.

(iv) ‘Public and “Track II” Diplomacy’ – Traditional Mediation happens behind closed doors between politicians. CHD engages the public directly. Initiatives like the British Museum’s ‘Bayeux Around Britain’ programme broaden the impact to schools and local communities. By humanising the ‘enemy’ or the ‘other’ at a grassroots level, it creates the social capital and public appetite necessary to sustain a political peace treaty.

CHD is a ‘Shield’ and not a ‘Weapon.’

You cannot safely transport a fragile historical artefact through a war zone. CHD usually requires a baseline ceasefire or a freeze in hostilities to be physically viable.

If a state feels its cultural heritage is being stolen or exploited during mediation, it will worsen the conflict rather than solve it.

Ultimately, as President Macron hoped for the future of Anglo-French relations, CHD is a tool to ‘forge a bond as close as the threads of this thousand-year-old embroidery.’ It should be viewed as an essential framework-builder, i.e. as the ‘psychological glue’ that binds a political peace agreement together and ensures it actually lasts.
