I'm don't know where you want your answer for, but I'm American so I'll answer for that. George Washington was the first president of the U.S. of A. after the Constitution was written. There were others before him, but I don't know their names.
Actually, it was John Hanson who had been president of the continental congress. Upon the constitution's ratification, Hanson became president of the United States. George Washington was the first elected president.
Dude these people are messing with your mind it's not George Washington it's obviously President Chuck Norris. He defeated the British army singlehandedly and built the White House have you never been to history class?
