What 1774 agreement created a unified colonial boycott of British goods before American independence?

The Continental Association created a unified colonial boycott of British goods in 1774.

The First Continental Congress adopted the agreement on October 20, 1774, in Philadelphia. It responded to the Coercive Acts, called the Intolerable Acts by many colonists, which Britain had enacted after the Boston Tea Party.

The Association called for nonimportation of British goods and encouraged local committees to monitor compliance. It also planned to restrict exports to Britain if colonial grievances were not addressed. The agreement was an early attempt to coordinate economic pressure across the colonies.

The Continental Association came before the Declaration of Independence and did not itself declare separation from Britain. The Olive Branch Petition, issued in 1775, was a separate effort to seek reconciliation with King George III. The Association is important because it helped create intercolonial cooperation before the 1776 break.
