when did the intolerable acts happen

The Intolerable Acts happened in 1774. They were a series of punitive laws passed by the British Parliament between March and June 1774 to punish the American colonies, particularly Massachusetts, for the Boston Tea Party. The acts included the closing of Boston's port starting June 1, 1774, and other measures such as restricting self-governance and allowing British troops to be housed in colonial buildings. The First Continental Congress convened later that year, from September 5 to October 26, 1774, in response to these acts. These events were significant in escalating tensions that led to the American Revolutionary War beginning in April 1775.
