The Declaration of Independence in 1776 emphasized ideals of liberty and individual rights for the American colonies, asserting their desire for autonomy from British rule. Authored primarily by Thomas Jefferson, this document articulated the colonies' grievances, emphasizing that all individuals are entitled to life, liberty, and the pursuit of happiness. The declaration was a revolutionary statement advocating for self-governance and human rights, serving not only as a justification for independence but also influencing future democratic movements around the world. It marked a foundational moment in American history.
