Answer:
The Presidential precedent of serving no more than two terms lasted for 144 years until it was broken by Franklin Delano Roosevelt.
Explanation:
George Washington and Thomas Jefferson were the ones who established, so the speak, the precedent of serving two terms. They did not run a third time, each for his own reasons. However, FDR broke that precedent after he won elections in 1932, 1936, 1940, and 1944. Roosevelt served for 12 years. Sadly, he passed away a few months after his last inauguration. It is important to note that Roosevelt was the first and only president to serve more than 2 terms. As a matter of fact, an amendment was passed by the Congress in 1947 preventing presidents from serving more than twice.
