Samuel Adams (September 27 [O.S. September 16], 1722 – October 2, 1803) was an American statesman, political philosopher, and a Founding Father. He was a politician in colonial Massachusetts, a leader of the movement that became the American Revolution, a signatory of the Declaration of Independence and other founding documents, 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 his fellow Founding Father, President John Adams. He founded the Sons of Liberty.
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 Parliament's efforts to tax the British American colonies without their consent.
