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:

• Boston Port Act (31 March 1774) - Closed the port of Boston to commercial shipping until the East India Company was compensated for the tea destroyed in December 1773 and the Crown was satisfied that order had been restored.
• Massachusetts Government Act (20 May 1774) - Substantially altered the Massachusetts charter, replacing the elected council with an appointed one, restricting town meetings, and granting the royal governor broad powers of appointment.
• Administration of Justice Act (20 May 1774) - Permitted the royal governor to transfer trials of crown officials accused of capital crimes to other colonies or to Great Britain if he determined a fair trial was unlikely in Massachusetts.
• Quartering Act (2 June 1774) - Applied to all colonies and required colonial authorities to provide housing for British troops in unoccupied buildings, including private structures, when barracks were unavailable.

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. See Coercive Acts Historiography Consensus.

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

• Parliamentary authority view - The acts represented a legitimate exercise of parliamentary sovereignty over the colonies, necessary to restore order after an act of organized destruction of private property. Parliamentary Authority Viewpoint
• Colonial rights view - The acts violated the constitutional rights of British subjects, abridged chartered liberties, and demonstrated that Parliament could not be trusted to legislate for the colonies. Colonial Rights Viewpoint
• Loyalist view - Many colonists opposed both the Tea Party and the acts, believing armed resistance to lawful authority was neither justified nor prudent, and that reconciliation remained preferable. Loyalist Viewpoint
• Imperial overreach view - Some British contemporaries, including Edmund Burke and William Pitt the Elder, argued the acts were politically counterproductive and constitutionally dubious even within a framework accepting parliamentary authority. Imperial Overreach Viewpoint
