Parliament closed the Port of Boston following the Boston Tea Party. In response, colonial leaders met in Philadelphia in a "Grand Congress." Tories supported the Congress as a way of putting off local talk of boycotts. They hoped emotions would cool after a few months. The Patriots hoped to use the Congress to enact a continent-wide boycott and present a united front in opposition to Parliament.
The summer of 1774, brought news of more of London's Coercive Acts. When Congress convened in September, public opinion favored the radicals. Congress issued the Declaration of Rights and Grievances, petitioned the King for repeal of the Coercive Acts, and agreed to a boycott of almost all trade until London met colonial demands.
