who was president when the berlin wall fell

The Berlin Wall fell on November 9, 1989. At that time, the President of the United States was George H.W. Bush. He had succeeded Ronald Reagan earlier that year in January 1989 and was in office during the historic moment of the wall's fall. While Reagan had famously challenged the Soviet leader to "tear down this wall" in a 1987 speech, it was under Bush's presidency that the actual event occurred, marking a key turning point in the end of the Cold War.
