Which president of the United States has served more than two terms?

Franklin roosevelt, re-elected for four terms. Before World War II, it was only a tradition that the President of the United States served two terms, and he could serve another term if he wanted. However, most of them still follow the old tradition, and after two sessions, they will say goodbye.

After World War II, the United States Congress passed a constitutional amendment, which fixed the tradition of serving only two terms in the form of constitutional provisions. Therefore, it is impossible for a person to serve two more terms unless the current political system is overthrown.
