In 1951, Congress ratified the 22nd Amendment, which prohibits United States presidents from serving more than two terms of four years each. Although there were many attempts to serve a third term preceding this amendment, only one president successfully served more than two terms: Franklin D. Roosevelt, who was elected in 1932, 1936, 1940, and 1944. Roosevelt's fourth term was cut short when he succumbed to illness. Following his presidency, Congress decided to ratify the 22nd Amendment to prevent future presidents from serving over two terms.

Over the course of 60 four-year terms, 45 individuals have held the American presidency a total of 47 times. Donald Trump, who initially served as the 45th president from 2017 to 2021, is now the 47th and current president. Per the 22nd Amendment, President Trump began his second term on January 20, 2025.
