The war that resulted in the independence of the United States was the American Revolutionary War, fought from 1775 to 1783. Tensions between the American colonies and British authorities had been escalating due to issues such as taxation without representation and restrictive governing policies. The conflict began with events like the Battles of Lexington and Concord and escalated into a full-scale war for independence. Significant victories at battles like Saratoga and Yorktown, combined with crucial alliances, particularly with France, culminated in the defeat of British forces. The war officially ended with the Treaty of Paris in 1783, affirming the sovereignty of the United States and shaping the future of the nation.
