The Boston Tea Party was an American political and mercantile protest by the Sons of Liberty in Boston, Massachusetts. The Intolerable Acts were punitive laws passed by the British Parliament in 1774 after the Boston Tea Party. The laws were meant to punish the Massachusetts colonists for their defiance in the Tea Party protest in reaction to changes in taxation by the British Government. Colonists who supported the British cause in the American Revolution were Loyalists, often called Tories, or, occasionally, Royalists or King's Men. George Washington's winning side in the war called themselves "Patriots", and in this article Americans on the revolutionary side are called Patriots.
