Uribe started his political career in his home department of Antioquia. He held offices in the Public Enterprises of Medellín and in the Ministry of Labor and was the director of the Special Administrative Unit of Civil Aeronautics (1980–1982). He became the Mayor of Medellín in October 1982. He was a senator between 1986 and 1994 and finally the Governor of Antioquia between 1995 and 1997 before being elected President of Colombia in 2002. Following his 2002 election, Uribe led an all-out military offensive against leftist guerrilla groups such as the FARC and the ELN with funding and backing from the Clinton and Bush administrations in the form of a 2.8 billion dollars direct foreign aid package called "Plan Colombia", as well as leading a controversial effort to demobilize the right-wing paramilitary group known as the AUC, all of which are part of the Colombian Armed Conflict. His role in the conflict was accompanied by large-scale alleged exactions: thousands of civilians were killed by the Colombian army, as part of the "False positives" scandal, with almost total impunity. Their deaths are being investigated by the United Nations. Millions of people have been victims of forced displacement.
