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.
Presidency of Salomé Zourabichvili
The presidency of Salomé Zourabichvili is the fifth presidency of Georgia since the country's independence from the Soviet Union in 1991, and the first presidency since the adoption of a new Constitution transforming Georgia into a parliamentary system in 2018. Beginning on December 16, 2018, Zourabichvili's term is set to be the longest term of any presidency in Georgia's history, as the transition into a new Constitution means that her mandate will last until 2024.
