What does Independence Day commemorate in the U.S.?

Independence Day in the United States, celebrated on July 4th, commemorates the adoption of the Declaration of Independence in 1776. This significant historical event marked the formal separation of the thirteen American colonies from British rule. The Declaration, authored primarily by Thomas Jefferson, articulated the colonies' grievances against King George III and asserted their right to be free and independent states. It symbolizes the establishment of the nation's values of liberty and democracy, making it a foundational moment in U.S. history.

In contrast, the signing of the Constitution represents a later stage in the development of American governance, specifically in 1787, while the start of the Civil War occurred decades later, in 1861. Similarly, the end of slavery, marked by the Emancipation Proclamation in 1863 and the subsequent passage of the 13th Amendment in 1865, is a vital part of American history but is not directly related to Independence Day, which focuses solely on independence from British monarchy.
