A major exhibition exploring the birth of the United States of America to coincide with the 250th anniversary of the Declaration of Independence on 4 July 2026.

Revolution 250: America's Independence Story 1763-1783 will open 24 June and feature some of the most significant letters, papers, maps and documents of that period, including a rare Dunlap print of the Declaration of Independence itself.

Dr Sean Cunningham, historian and curator at The National Archives, yesterday said:

Revolution 250 will explore two pivotal decades that reshaped the world, tracing the dramatic rise and eventual fall of British power in America.

At its heart is the Declaration of Independence on 4 July 1776 – a moment that changed history.

Our records reveal the story of the American Revolution, and highlight the personal experiences of so many who had a stake in the fate of British America.

Also on display will be the Tea Act which ultimately led to the Boston Tea Party, a British officer’s account of the tea party itself, the ‘Olive Brach petition’ sent to George III from representatives of the 13 colonies in a last attempt to avoid war in July 1775, George III’s Proclamation of Rebellion declaring that the colonies were in open revolt, and the Treaty of Paris ending the war with Britain accepting American independence.

Saul Nassé, Chief Executive at The National Archives, yesterday said:

In this momentous year we are excited to be able to showcase the unique documents in our collection to explore the birth of what we now know as the United States of America.

Following on from our hugely successful MI5: Official Secrets exhibition which has been extended until the end of November, we are sure visitors will be informed, educated, and entertained.
