when did the north american colonies break away from great britain
American Revolution The Continental Army forced the British out of Boston in 1776, but the British captured and held New York City for the duration of the war. The British blockaded ports and captured other cities for brief periods, but they failed to defeat Washington's forces. The Patriots unsuccessfully attempted to invade Canada during the winter of 1775–76, but they captured a British army at the Battle of Saratoga in late 1777, and the French entered the war as allies of the United States as a result. The war later turned to the American South where the British under the leadership of Charles Cornwallis captured an army at South Carolina but failed to enlist enough volunteers from Loyalist civilians to take effective control of the territory. A combined American–French force captured a second British army at Yorktown in 1781, effectively ending the war in the United States. The Treaty of Paris in 1783 formally ended the conflict, confirming the new nation's complete separation from the British Empire. The United States took possession of nearly all the territory east of the Mississippi River and south of the Great Lakes, with the British retaining control of Canada and Spain taking Florida.
American Revolutionary War Whigs in Britain had long opposed the pro-war Tories in Parliament, and the surrender gave them the upper hand. In early 1782, Parliament voted to end all offensive operations in North America, but the war continued in Europe and India. Britain remained under siege in Gibraltar but scored a major victory over the French navy. On September 3, 1783, the belligerent parties signed the Treaty of Paris in which Great Britain agreed to recognize the sovereignty of the United States and formally end the war. French involvement had proven decisive,[44] but France made few gains and incurred crippling debts. Spain made some minor territorial gains but failed in its primary aim of recovering Gibraltar.[45] The Dutch were defeated on all counts and were compelled to cede territory to Great Britain. In India, the war against Mysore and its allies concluded in 1784 without any territorial changes.
