The Intolerable Acts, passed by the British Parliament in 1774, were a significant catalyst for the American Revolution. These punitive measures aimed to suppress dissent following the Boston Tea Party and included closing Boston Harbor and revoking Massachusetts' charter. The severity of these acts united the colonies against British rule, fostering solidarity and spurring the formation of the First Continental Congress. The Intolerable Acts exemplified British oppression, ultimately leading to the colonists' determination to fight for independence. This response to perceived tyranny signified a turning point in colonial relations with Britain, laying the groundwork for the Revolutionary War.
