Answer:
The American Revolution was a period of political change after 1763 in the thirteen British colonies in North America which led to the American War of Independence against Great Britain (1775-1783). The founding episode of the American nation and the birth of the United States, the revolution manifested itself in violence against the British authorities, a war against the metropolis and social unrest.
In order to amortize the cost of the Seven Years' War (1756-1763), Great Britain imposed taxes on its thirteen colonies in North America without consulting them; the American colonists protested with king George III and the Parliament of the United Kingdom, then launched a revolt which the metropolis tried to suppress by sending troops. On July 4, 1776, representatives of the colonies meeting in Philadelphia adopted the Declaration of Independence, and after a series of setbacks from the Continental Army commanded by George Washington, the war against Great Britain turned to the advantage of the Americans. The patriots received help from many Europeans, then from the government of Louis XVI, Spain and the United Provinces. In 1783 London recognized the independence of the United States.
