On July 18, 1940, Roosevelt was nominated for a third presidential term at the Democratic Party convention in Chicago. The president received some criticism for running again because there was an unwritten rule in American politics that no U.S. president should serve more than two terms. Thecustom dated back to the country’s first president, George Washington, who in 1796 declined to run for a third term in office. Nevertheless, Roosevelt believed it was his duty to continue serving and lead his country through the mounting crisis in Europe, where Hitler’s Nazi Germany was on the rise. The president went on to defeat Republican Wendell Wilkie in the general election, and his third term in office was dominated by America’s involvement in World War II.
In 1944, with the war still in progress, Roosevelt defeated New York governor Thomas Dewey for a fourth term in office. However, the president was unable to complete the full term. On April 12, 1945, Roosevelt, who had suffered from various health problems for years, died at age 63 in Warm Springs, Georgia. He was succeeded by Vice President Harry S. Truman. On March 21, 1947, Congress passed the 22nd Amendment to the U.S. Constitution, which stated that no person could be elected to the office of president more than twice. The amendment was ratified by the required number of states in 1951.
