The Intolerable Acts, also known as the Coercive Acts, were a series of punitive laws enacted by the British Parliament in 1774 in response to the Boston Tea Party. These acts aimed to suppress colonial dissent and included measures such as closing Boston Harbor, altering the Massachusetts government, and allowing royal officials to be tried in Britain for crimes committed in the colonies. The Intolerable Acts galvanized colonial opposition and were a significant catalyst for the American Revolution, leading to the formation of the First Continental Congress.
