when was reagan president

Ronald Reagan was president of the United States from January 20, 1981, to January 20, 1989.

He served two full four-year terms as the 40th president, after defeating Jimmy Carter in the 1980 election and then winning re‑election in 1984. His presidency therefore covered most of the 1980s, a period often associated with the late Cold War, the rise of conservative politics in the U.S., and major economic and defense policy shifts.
