George Washington was the first president of the United States and established many precedents for the office. He led the Continental Army to victory in the American Revolutionary War and was unanimously elected president in 1789. As president, he established the structure and leadership of the executive branch by creating the first presidential cabinet. Washington faced tensions between Alexander Hamilton and Thomas Jefferson over domestic and foreign policy which led to the formation of political parties. He issued the Proclamation of Neutrality to keep the U.S. out of conflicts between France and Britain and signed Jay's Treaty to normalize relations with Britain.
