AMERICAN INDEPENDENCE, WAR OF (1775–1783). The War of American Independence began on 19 April 1775 with firefights at Lexington and Concord, Massachusetts. It ended on 28 June 1783, when a British force ceased operations against the French, who were aiding rebels in southern India. Barring Vietnam, it was the longest war in the history of the United States to the twenty-first century. It involved most European powers as either belligerents or watchful observers. In one way or another it touched every part of what had been British America, including not only the thirteen east coast colonies but also Canada and Native American country as well as the West Indies and the open Atlantic. The war destroyed one empire and created another.
The war was not synonymous with the American Revolution. That larger civil, cultural, social, and economic transformation sprawled over a quarter century between the first colonial challenges to British authority in 1764 and the implementation of the U.S. Constitution in 1789. Unlike the later Southern war to preserve slavery and destroy the United States, it does not have a military narrative strong enough to carry the whole story of the American Republic's creation. But the war was central to the Revolution's process and its outcome.
