From 1774 to 1789, the Continental Congress served as the government of the 13 American colonies and later the United States. The First Continental Congress, which was comprised of delegates from the colonies, met in 1774 in reaction to the Coercive Acts, a series of measures imposed by the British government on the colonies in response to their resistance to new taxes. In 1775, the Second Continental Congress convened after the American Revolutionary War (1775-83) had already begun. In 1776, it took the momentous step of declaring America’s independence from Britain. Five years later, the Congress ratified the first national constitution, the Articles of Confederation, under which the country would be governed until 1789, when it was replaced by the current U.S. Constitution.
