The 22nd Amendment to the United States Constitution set a two-term limit on the President. Franklin D. Roosevelt was the only President to serve three terms, and died before completing his fourth.
At the time, there were no laws prohibiting a president from serving more than 2 consecutive terms in office. The advent of World War II was a contributing factor to both FDR's decision to run for a 3rd (and 4th) term, and to his relatively easy victories.
It should be added, though, that FDR didn't serve 4 terms. He was elected 4 times, but died a only few weeks into the 4th term, and was succeeded by Harry Truman.
The 22nd Amendment to the Constitution of the United States was ratified on February 27, 1951 and reads in part:
"No person shall be elected to the office of the President more than twice, and no person who has held the office of President, or acted as President, for more than two years of a term to which some other person was elected President shall be elected to the office of the President more than once."

Franklin Pierce was elected President in 1852 . The national election was held on November 2, 1852.
For the most part Franklin D. Roosevelt won the election for president in 1932 because of the dire straits of the US economy. The sitting president, US President Hoover, was blamed for the depression. To many people Roosevelt was seen as the best hope to have the economy recover.
This amendment was prompted by the election of 1800 and the problems occurring in the election of President Thomas Jefferson and his running mate Aaron Burr.
The 12th amendment has this effect. It provides for separate elections of the president and vice-president.
The direct consequence of the election of 1800 was the amendment to the constitution that stipulated separate electoral college balance for president and vice president. It was the 12th amendment to be added to the constitution.
