The term Founding Fathers of the United States of America refers broadly to the individuals of the Thirteen British Colonies in North America who led the American Revolution against the authority of the British Crown and established the United States of America. It is also used more narrowly, referring specifically to those who either signed the Declaration of Independence in 1776 or who were delegates to the 1787 Constitutional Convention and took part in drafting the proposed Constitution of the United States. A further subset includes those who signed the Articles of Confederation. During much of the 19th century, they were referred to as either the "Founders" or the "Fathers".
