The Founding Fathers of the United States were the political leaders who signed the Declaration of Independence in 1776 or otherwise took part in the American Revolution in winning American independence from Great Britain, or who participated in framing and adopting the United States Constitution in 1787-1788, or in putting the new government under the Constitution into effect. Within the large group known as "the founding fathers," there are two key subsets, the Signers (who signed the Declaration of Independence in 1776) and the Framers (who were delegates to the Federal Convention and took part in framing or drafting the proposed Constitution of the United States).
