After the Glorious Revolution in 1689, Bostonians overthrew royal governor Sir Edmund Andros. They seized dominion officials and adherents to the Church of England during a popular and bloodless uprising. These tensions eventually culminated in the American Revolution, boiling over with the outbreak of the War of American Independence in 1775. The first battles of the war were fought in Lexington and Concord, Massachusetts, later leading to the Siege of Boston by continental troops. In March 1776, British forces were compelled to retreat from Boston.
