The Coercive Acts were four laws passed by the Parliament of Great Britain in 1774 in response to colonial resistance, particularly the Boston Tea Party of December 1773. The acts were known in the colonies as the Intolerable Acts and were intended to reassert British authority over Massachusetts and discourage further resistance. They are regarded as a primary cause of the American Revolution. A fifth act, the Quebec Act, was passed around the same time and is often grouped with the four Coercive Acts by colonial contemporaries, though it addressed different policy objectives.
The four acts comprising the Coercive Acts were passed between March and June 1774:
The Quebec Act (22 June 1774) extended the boundaries of the Province of Quebec southward to the Ohio River, established Roman Catholicism as a recognized religion in Quebec, and restored French civil law for private matters. Colonial leaders grouped it with the four Coercive Acts in their protests, viewing it as a threat to territorial claims, Protestant religious interests, and representative governance, though British officials framed it as an administrative measure for the recently acquired territory. Modern historians generally treat it as legislatively distinct from the four Coercive Acts.
The acts followed years of escalating tension over taxation and parliamentary authority, including controversies over the Stamp Act (1765), the Townshend Acts (1767), and the Boston Massacre (5 March 1770). The Tea Act of 1773 had prompted the Boston Tea Party, which Parliament treated as an act of open defiance requiring a firm legislative response. The full legislative and political history of the Coercive Acts covers the parliamentary debates, colonial responses, and the acts' role in precipitating the First Continental Congress.
Rather than isolating Massachusetts, the acts prompted coordinated intercolonial response. The First Continental Congress convened in Philadelphia in September 1774, with delegates from twelve of the thirteen colonies. Congress adopted the Continental Association, organizing a boycott of British goods, and issued declarations asserting colonial rights. Several colonies sent expressions of support and material aid to Massachusetts. British officials including General Thomas Gage, appointed military governor of Massachusetts, found enforcement difficult and reported that colonial resistance was broader and more organized than anticipated.
Historians broadly agree on the factual sequence of events and the acts' role in precipitating the First Continental Congress and the subsequent outbreak of hostilities. Interpretive questions - including whether Parliament's response was proportionate, whether reconciliation remained possible after 1774, and how the acts fit into broader theories of imperial administration - remain subjects of ongoing scholarly discussion.

Contemporary and historical observers have disagreed about the justification, legality, and effects of the acts:
