The American Revolutionary War began in 1775 with several key events that led to the colonists declaring independence from Britain. The causes of the war included Britain imposing taxes on the colonies to pay off war debts without colonial representation. Major battles included Bunker Hill, Trenton, Saratoga, and Yorktown. With support from France after the Battle of Saratoga, the Americans were able to turn the tide of the war. The war ended with the Treaty of Paris in 1783, which recognized American independence and established the new borders of the United States.
