The Continental Congress was the legislative assembly, composed of delegates of the Thirteen Colonies, which convened twice, before and during the American War of Independence respectively. The first meeting of the Continental Congress took place in Philadelphia, Pennsylvania, from September 5 to October 26, 1774; the purpose of the First Congress was to petition the British government, led by Prime Minister and Chancellor of the Exchequer Frederick North (Lord North) under George III, for a redress of grievances in response to the British Intolerable Acts, one of which was the closure or blockade of the port of Boston. The intolerable Acts had been passed as a result of the Tea Party destruction of tons of tea belonging to the East India Company.
The second meeting or session of the Continental Congress took place in Philadelphia, Pennsylvania, from May 10, 1775, to 1780. It issued the Declaration of Independence and established the Articles of Confederation, which was the Constitution of the Thirteen Colonies adopted temporarily in 1781.
