George Washington was the leader of the American forces during the Revolutionary War. Appointed as the Commander-in-Chief of the Continental Army in 1775, he played a crucial role in organizing and leading the colonial militia against British forces. Washington's military strategies, resilience, and ability to unite disparate factions were vital to American success. He oversaw significant victories, such as the Siege of Yorktown in 1781, which ultimately led to American independence. Following the war, Washington became a key figure in the founding of the United States, serving as its first President.
