George Washington
At the end of his second term, Washington retired for personal and political reasons, fatigued and disgusted with personal attacks, and to assure a truly contested presidential election could be held. He did not feel bound to a two-term limit, but his retirement ultimately set precedent. The two-term limit to the presidency was formalized with the 1951 adoption of the Twenty-second Amendment to the United States Constitution. Washington is often credited with setting the principal of a two-term presidency, but it was Thomas Jefferson who first refused to run for a third term on political grounds.

When Vargas were deposed, new elections were summoned for a Constituent Assembly and a president, both chosen by direct popular ballot. The first presidential term subsequent to the deposition of the Estado Novo dictatorship began on 31 January 1946, and the Constitution adopted on 18 September 1946 established five-year presidential terms, but did not change the Inauguration Day. Accordingly, the subsequent five-year presidential terms also started on 31 January.
