Which body met in Philadelphia in 1774 to coordinate colonial resistance to British policies before independence?

The body that met in Philadelphia in 1774 to coordinate colonial resistance was the First Continental Congress.

Delegates from 12 of the 13 British colonies met at Carpenters' Hall from September 5 to October 26, 1774. Georgia did not send delegates. The meeting followed Parliament's passage of the Coercive Acts, called the Intolerable Acts by many colonists, after the Boston Tea Party.

The First Continental Congress did not declare independence. Instead, it adopted the Continental Association, which organized a boycott of British goods, and sent a petition to King George III. Its actions created a framework for intercolonial cooperation.

The Second Continental Congress met the following year, after fighting began at Lexington and Concord. It directed the Revolutionary War and eventually adopted the Declaration of Independence, making it distinct from the earlier congress.
