On April 30, 1789, George Washington took the oath of office with what later became known as the shortest inauguration address. Since then, Presidential Inauguration ceremonies, which are driven by tradition, have grown to include musical performances, oaths, parades, and addresses, usually stressing the importance of unity. The peaceful transfer of power that has occurred on every U.S. Inauguration Day will begin today at 9:30 a.m. Donald Trump will take the oath of office to formally become the 45^th President of the United States around noon.
