The First Continental Congress met at Carpenters' Hall in Philadelphia in 1774.
Delegates from twelve of the Thirteen Colonies gathered there from September 5 to October 26, responding chiefly to Britain's Intolerable Acts. Georgia was the only colony that did not send delegates. The meeting took place before the colonies openly declared independence, so its immediate goal was coordinated resistance and a petition to King George III.
Carpenters' Hall was built by the Carpenters' Company of the City and County of Philadelphia. It was a practical meeting place near the Pennsylvania State House, now known as Independence Hall. The Congress adopted the Continental Association, which organized a boycott of British goods. The following year, the Second Continental Congress met in the Pennsylvania State House and directed the Revolutionary War effort.
A common mix-up is assuming that the First Continental Congress met at Independence Hall. That building hosted the Second Continental Congress, including the debate and adoption of the Declaration of Independence in 1776.
