In response to the British Parliament's enactment of the so-called Intolerable Acts, representatives from twelve of the Thirteen Colonies convened the First Continental Congress at Carpenters' Hall in Philadelphia.

The Parliament of the United Kingdom of Great Britain and Northern Ireland is the supreme legislative body of the United Kingdom, and may also legislate for the Crown Dependencies and the British Overseas Territories. It meets at the Palace of Westminster in London. Parliament possesses legislative supremacy and thereby holds ultimate power over all other political bodies in the United Kingdom and the Overseas Territories. While Parliament is bicameral, it has three parts: the sovereign, the House of Lords, and the House of Commons. The three parts acting together to legislate may be described as the King-in-Parliament. The Crown normally acts on the advice of the prime minister, and the powers of the House of Lords are limited to only delaying legislation.

The Intolerable Acts, sometimes referred to as the Insufferable Acts or Coercive Acts, were a series of five punitive laws passed by the British Parliament in 1774 after the Boston Tea Party. The laws aimed to collectively punish Massachusetts colonists for the actions of those protesting the Tea Act, a tax measure enacted by Parliament in May 1773, by dumping tea into Boston harbor. In Great Britain, these laws were referred to as the Coercive Acts. Many Massachusetts colonists considered them a "virtual declaration of war" by the British government. They were a key development leading to the outbreak of the American Revolutionary War in April 1775.

The Thirteen Colonies were the English colonies and later British colonies on the Atlantic coast of North America which broke away from the British Crown in the American Revolutionary War (1775–1783), and joined to form the United States of America.

The First Continental Congress was a meeting of delegates of twelve of the Thirteen Colonies held from September 5 to October 26, 1774, at Carpenters' Hall in Philadelphia at the beginning of the American Revolution. The meeting was organized by the delegates after the British Navy implemented a blockade of Boston Harbor and the Parliament of Great Britain passed the punitive Intolerable Acts in response to the Boston Tea Party.
