AMERICAN REVOLUTION

American Revolution (1775-1783), conflict between 13 British colonies in North America and their parent country, Great Britain. It was made up of two related events: the American War of Independence (1775-1783) and the formation of the American government as laid out by the Constitution of the United States in 1787. First, the war achieved independence from Great Britain by the colonies. Second, the newly created United States of America established a republican form of government, in which power resided with the people.

The revolution had many causes. Long-term social, economic, and political changes in the colonies before 1750 provided the basis for an independent nation with representative political institutions. More immediately, the French and Indian War (1754-1763) changed the relationship between the colonies and their mother country. Finally, a decade of conflicts between the British government and the colonists, beginning with the Stamp Act crisis in 1765, led to the outbreak of war in 1775 and the Declaration of Independence in 1776.

Once independent, the new state governments implemented republican constitutions, and a Continental Congress directed the American war effort. Then in 1781 the rebellious states created a loose union under the Articles of Confederation. At the end of the war in 1783, Britain recognized its former colonies as an independent nation. In 1789 the people of the several states ratified the Constitution that created a stronger central government.
