In August 1921, while the Roosevelt family was on vacation in Campobello Island, New Brunswick, Franklin became ill with polio, a viral infection of the nerve fibers of the spine, which he probably contracted by swimming in the standing water of a nearby lake. The result was that Roosevelt was totally and permanently paralyzed from the waist down. Initially, the muscles of his abdomen and the lower part of his back were also affected, but later recovered. In this way, he could get up and, with the help of crutches, stand up, but he could not walk.

As a result of the illness, Roosevelt departed from the public scene for a time. The great majority of the epigones of the American policy assumed that the shining heir of the Roosevelt dynasty would never return to politics.

The belief that he would not return to politics was denied when a renewed (although still affected by polio) Roosevelt left his retirement to run for governor of New York, winning the election with an impressive success, after which he sought the Democratic nomination in 1932 for the presidency of the United States, obtaining it quite easily and thus launching his candidacy.

His campaign was a success and Roosevelt was elected president, position for which he would run again in 1936, 1940 and 1944. He won all of them and held the presidency for a period of more than 12 years, which would have been 16 if it were not for his sudden death. On April 12, 1945, during the first year of his last term, he died on his desk while working.
