The event the U.S. celebrated on the 50th anniversary of its independence was the centennial of the Declaration of Independence, which took place on July 4, 1826. This significant date coincided with the deaths of two founding fathers, Thomas Jefferson and John Adams, who were pivotal figures in the American Revolution and the drafting of the Declaration. Their passing marked a profound moment in history. Celebrations included parades, speeches highlighting the ideals of liberty and democracy, and reflections on the nation's origins. Commemorating this anniversary served to reinforce national identity and pride in the U.S. and its democratic values.
