"United States Declaration of Independence" by Thomas Jefferson is a founding document written in 1776. Drafted by Jefferson and edited by the Continental Congress, it explains why the Thirteen Colonies declared themselves independent from British rule. The document lists colonial grievances against King George III and asserts natural rights, including life, liberty, and the pursuit of happiness. Signed by delegates who risked execution for treason, it became one of history's most influential statements on human rights and self-governance. (This is an automatically generated summary.)
