Boston quickly became the political, commercial, financial, religious and educational center of the New England region.  The American Revolution erupted in Boston, as the British retaliated harshly for the Boston Tea Party and the patriots fought back.  They besieged the British in the city, with a famous battle at Bunker Hill in Charlestown on June 17, 1775 (which was lost by the colonists, but inflicted great damage against the British) and won the Siege of Boston, forcing the British to evacuate the city on March 17, 1776.  However, the combination of American and British blockades of the town and port during the conflict seriously damaged the economy, and the population fell by two thirds in the 1770s.
