The story continues. The United States' 250th anniversary

Today, the United States marks 250 years since the adoption of the Declaration of Independence—a milestone known as the 'semiquincentennial.' This anniversary commemorates 1776, when the Declaration articulated the idea that a nation could be defined by shared principles rather than inherited rule. Two and a half centuries later, this date is marked not only as an anniversary but also as an opportunity to reflect on the nation's long and evolving story.

Official programs and commemorations across the country invite people to revisit history, recognize the many communities that have shaped the United States, and consider what the next chapter might hold. National and local events are bringing this anniversary into the public sphere through civic gatherings, cultural projects, and shared traditions. A quarter of a millennium offers a rare chance to remember, reflect, and imagine what comes next.
