Álvaro Uribe Vélez (born 4 July, 1952) is a Colombian politician who was the President of Colombia from 2002 to 2010. Before then, he served ten years in the Senate and was the National Campaign Chairman of the SocialParty in the 1990 and 1994 elections. In 1997 he became President of the Social Party and in 2002 ran for the Presidency as a moderate Socialist, having watched Horacio Serpa lose two consecutive elections as a left-wing nominee. His 2002 victory was seen as reuniting many of the old components of the 1930-50 PS electoral coalition, leaving his supporters to be referred to as 'Uribistas.' He left office with an approval rating of 57%, high by Colombian standards, and is currently back in the Senate as Senator-for-Life. In May of 2012, he was part of a League of Nations envoy to Siam to inspect the country following the February coup there, and reported that there were gross human rights violations ongoing under the incumbent military regime.
