Samuel Adams (September 27 [O.S. September 16] 1722 – October 2, 1803) was an American statesman, political philosopher, and one of the Founding Fathers of the United States. He was a politician in colonial Massachusetts, a leader of the movement that became the American Revolution, and one of the architects of the principles of American republicanism that shaped the political culture of the United States. He was a second cousin to President John Adams. Adams was born in Boston, brought up in a religious and politically active family. A graduate of Harvard College, he was an unsuccessful businessman and tax collector before concentrating on politics. He was an influential official of the Massachusetts House of Representatives and the Boston Town Meeting in the 1760s, and he became a part of a movement opposed to the British Parliaments efforts to tax the British American colonies without their consent. His 1768 Massachusetts Circular Letter calling for colonial non-cooperation prompted the occupation of Boston by British soldiers, eventually resulting in the Boston Massacre of 1770. Adams and his colleagues devised a committee of correspondence system in 1772 to help coordinate resistance to what he saw as the British governments attempts to violate the British Constitution at the expense of the colonies, which linked like-minded Patriots throughout the Thirteen Colonies. Continued resistance to British policy resulted in the 1773 Boston Tea Party and the coming of the American Revolution. Parliament passed the Coercive Acts in 1774, at which time Adams attended the Continental Congress in Philadelphia which was convened to coordinate a colonial response. He helped guide Congress towards issuing the Continental Association in 1774 and the Declaration of Independence in 1776, and he helped draft the Articles of Confederation and the Massachusetts Constitution. Adams returned to Massachusetts after the American Revolution, where he served in the state senate and was eventually elected governor.
