The leader of the American opposition to British rule during the Revolutionary War was George Washington. As commander-in-chief of the Continental Army, Washington played a crucial role in strategizing and leading the colonial forces against the British. His leadership was marked by significant victories, such as the surprise attack at Trenton and the decisive win at Saratoga, which bolstered colonial morale. Washington's ability to unite diverse colonial factions and maintain an army despite significant challenges ultimately earned him the respect and loyalty of his contemporaries. After the war, he became the first President of the United States, further solidifying his legacy.
