who was the president that served more than two terms
List of Presidents of the United States by time in office William Henry Harrison spent the shortest time in office, and Franklin D. Roosevelt spent the longest. He is the only president to have served more than two terms. Following ratification of the 22nd Amendment in 1951, presidents—beginning with Dwight D. Eisenhower—have been ineligible for election to a third term or for election to a second full term after serving more than two years of a term to which some other person was elected president. The amendment contained a grandfather clause that explicitly exempted the incumbent president—then Harry S. Truman—from the new term limitations.
Term of office In the United States, the president of the United States is elected indirectly through the United States Electoral College to a four-year term, with a term limit of two terms (totaling eight years) or a maximum of ten years if the president acted as president for two years or less in a term where another was elected as president, imposed by the Twenty-second Amendment to the United States Constitution, ratified in 1951.
