The Framers of the Constitution considered a six or seven-year term for the president before deciding on a four-year term with the option of reelection. Although the Constitution did not place a limit on the number of times a president can be reelected, President George Washington established the precedent of not seeking a third term.
A president not serving more than two terms. This custom was broken by President Franklin D. Roosevelt, and soon after, the 22nd Amendment came to limit a president to a maximum of two terms.
The first, and only president elected for a third term was Franklin D. Roosevelt in 1940 due to some concerns during WWII. He was also elected in 1947 for a fourth term, but died only months into his fourth term.
