The American Revolution developed after decades of growing tension between Britain and its American colonies. For much of the 1600s and early 1700s, the colonies enjoyed significant self-government while Britain loosely enforced trade regulations. However, after the costly French and Indian War ended in 1763, Britain sought to raise revenue and tighten control through new taxes and trade restrictions, including the Sugar Act, Stamp Act, and Townshend Acts. Colonists also became frustrated by limits on westward expansion and by having no representation in Parliament. Protests such as the Boston Tea Party led Britain to impose the Intolerable Acts, further increasing colonial resentment. By 1776, many Americans believed their rights were no longer being protected by the British Crown and concluded that independence was necessary to govern themselves and preserve their freedoms.
