Third inauguration of Franklin D. Roosevelt
The third inauguration of Franklin D. Roosevelt as president of the United States was held on Monday, January 20, 1941, at the East Portico of the United States Capitol in Washington, D.C. This was the 39th inauguration and marked the commencement of the third and eventually final full term of Franklin D. Roosevelt as president and the only term of Henry A. Wallace as vice president. This was the first and only time a president has been inaugurated for a third term; after the Twenty-second Amendment to the United States Constitution was ratified in 1951, no person can be elected president more than twice, though three terms are still allowed provided at least one partial term of 2 years or less.
