PARIS: Vladimir Putin won Russia's presidential election on Sunday, giving him a fourth term that will take him to nearly a quarter-century as the head of state or government.
Here are some of the world leaders who have held power the longest -- excluding monarchs enthroned for life.
More than four decades
Topping the list with 49 years in power is Cuba's revolutionary hero Fidel Castro, who handed over to his brother Raul in 2008 when he was in his early 80s.
Taiwan's first president Chiang Kai-shek was in charge on the island and in mainland China for a total of 47 years until his death in 1975.
North Korean founder Kim Il Sung ran the reclusive state for 46 years before dying in office in 1994. He is still revered as the "eternal leader".
Albania's communist dictator Enver Hoxha was in power for 40 years until his death in 1985.
Moamer Kadhafi ruled Libya with an iron fist for almost 42 years before being ousted and then slaughtered in 2011 by rebels.
