American Revolutionary War

The American Revolutionary War (1775–1783), also sometimes known as the American War of Independence, began as a war between the Kingdom of Great Britain and thirteen united former British colonies in North America, and concluded in a global war between several European great powers. The war was the culmination of the political American Revolution, whereby the colonists rejected the legitimacy of the Parliament of Great Britain to govern them without representation, claiming that this violated the Rights of Englishmen. In 1775, revolutionaries gained control of each of the thirteen colonial governments, set up the Second Continental Congress, and formed a Continental Army. Petitions to the king to intervene with the parliament for them resulted in Congress being declared traitors and the states in rebellion the following year. The Americans responded in 1776 by formally declaring their independence as a new nation — the United States of America — claiming sovereignty and rejecting on the basis of tyranny any allegiance to the British monarchy. Although France had been providing supplies, ammunition and weapons to the rebels beginning in 1776, the Continentals' capture of a British army in 1777 led France to formally enter the war on the side of the United States in early 1778, which evened the military strength with Britain. Spain and the Dutch Republic – French allies – also went to war with Britain over the next two years.

Throughout the war, the British were able to use their naval superiority to capture and occupy coastal cities, but control of the countryside (where 90% of the population lived) largely eluded them because of the relatively small size of their land army. French involvement proved decisive, with a French naval victory in the Chesapeake leading at Yorktown in 1781 to the surrender of a second British army. In 1783, the Treaty of Paris ended the war and recognized the sovereignty of the United States over the territory bounded by what is now Canada to the north, Florida to the south, and the Mississippi River to the west.
