Between 1750-1789, the American colonies grew increasingly unhappy with British rule as Britain imposed new taxes without colonial consent to pay off debts from the Seven Years' War. This led to unrest and demonstrations like the Boston Tea Party in 1773. In 1776, the colonies declared independence from Britain and fought the Revolutionary War until 1783 when Britain recognized American independence in the Treaty of Paris. After the war, the new nation worked to establish a stable government, debating between the Federalists who favored a strong central government and the Antifederalists who opposed centralized power. This debate was resolved with the ratification of the U.S. Constitution in 1789.
