On 4 July 2026, the United States of America will celebrate one of the most significant milestones in modern history: the 250th anniversary of the Declaration of Independence. Known as the Semiquincentennial, this historic occasion marks a quarter of a millennium since the thirteen American colonies declared their independence from the British Empire and began the ambitious experiment of building a new nation based on liberty, self-government and individual rights.
Few countries have had a greater impact on the modern world than the United States. During its first 250 years, America evolved from a small collection of colonies along the Atlantic coast into the world’s largest economy, a technological superpower, a leader in science and innovation, and one of the most influential political and military forces in history.
