By the 1770s, Great Britain ruled a vast empire, with its American colonies producing useful raw materials and profitably consuming British goods. From Britain’s perspective, it was inconceivable that the colonies would wage a successful war for independence; in 1776, they appeared weak and disorganized, no match for the Empire. Yet, although the Revolutionary War did indeed drag on for eight years, in 1783, the thirteen colonies, now the United States, ultimately prevailed against the British. The Revolution succeeded because colonists from diverse economic and social backgrounds united in their opposition to Great Britain. Although thousands of colonists remained loyal to the crown and many others preferred to remain neutral, a sense of community against a common enemy prevailed among Patriots.
