The Fourth of July commemorates the adoption of the Declaration of Independence in 1776. On this day, the Thirteen American Colonies declared their independence from British rule, asserting their rights and freedoms. The Declaration, primarily authored by Thomas Jefferson, outlined grievances against King George III and articulated the colonies' intent to be self-governing. Celebrations typically involve fireworks, parades, barbecues, and gatherings that embody American patriotism and heritage. The holiday signifies the birth of the United States as a nation, reflecting the ideals of liberty, equality, and the pursuit of happiness, which continue to resonate in American culture today.
