American Revolution: 250 Years from the Declaration of Independence

American Revolution: 250 Years from the Declaration of Independence opens at the British Library on Monday 29 June 2026 and runs until Sunday 17 January 2027. It's a display marking the 250th anniversary of the United States' Declaration of Independence, and it sits in the Treasures Gallery (the Sir John Ritblat Gallery) as part of the library's permanent collection.

The exhibition traces how the Declaration came into being and how its most famous line—'all men are created equal'—has shaped debates, inspired movements and been interpreted over the two and a half centuries that followed. It's a four-case presentation that draws on unique items from the British Library's own collections: letters, maps and other documents from the American Revolution. From there, it follows the thread to later civil rights leaders like Frederick Douglass and Martin Luther King Jr., showing how they drew on the Declaration's ideals in their own fights for freedom and equality.

Because it's part of the Treasures of the British Library permanent gallery, you can see it whenever the building is open. It's free, and there's no booking required, so you can just drop in when you're around the area. It runs from 29 June 2026 through to 17 January 2027, so there's plenty of time to catch it if you're not in the city this summer.
