The conflict that led to the independence of the United States from British rule was the American Revolutionary War, which lasted from 1775 to 1783. Tensions had escalated over various issues, including taxation without representation, British military presence, and restrictions on colonial trade. The war was ignited by events such as the Boston Tea Party and the Battles of Lexington and Concord. Ultimately, the colonies declared their independence with the adoption of the Declaration of Independence in 1776. The victory at Yorktown in 1781, followed by the Treaty of Paris in 1783, secured the independence of the United States.
