British America comprised the colonial territories of the English Empire, and the successor British Empire, in the Americas from 1607 to 1783.
These colonies were formally known as British America and the British West Indies immediately prior to thirteen of the colonies seceding in the American Revolutionary War (1775–1783) and forming the United States of America.

The Thirteen Colonies were a group of British colonies on the Atlantic coast of North America during the 17th and 18th centuries. Grievances against the imperial government led the 13 colonies to begin uniting in 1774, and expelling British officials by 1775. Assembled at the Second Continental Congress in Philadelphia, they appointed George Washington as commander-in-chief of the Continental Army to fight the American Revolutionary War. In 1776, Congress adopted the Declaration of Independence as the United States of America. Defeating British armies with French help, the Thirteen Colonies gained sovereignty with the Treaty of Paris in 1783.
