The term "Founding Fathers" refers to the group of men who were responsible for founding or establishing a country, organization, or movement. In the context of American history, it specifically refers to the 56 delegates who signed the Declaration of Independence in 1776 and the 38 members of Congress who approved the Constitution in 1787. These men are considered as the key figures responsible for shaping the political and social institutions of the United States, including its system of government, Bill of Rights, and democratic principles.
