Washington, wary of the dangers posed by an individual's becoming entrenched in the presidency, created a two-term tradition that remained intact until Franklin Delano Roosevelt's third consecutive election in 1940.
Franklin Delano Roosevelt (FDR) is the only us president in history that served more than two terms in office. In fact, he was elected to four full terms. Unfortunately, Roosevelt died during his fourth term, and the remainder was served by his vice president, Harry S Truman. Shortly after, in 1947, the 22 Amendment of the United States Constitution was passed. It stated that a president cannot serve more than 10 years or two consecutive terms in office.
