After the siege, Petro used his influence within M-19 to promote peace talks with the government, helping to bring about the eventual dismantling of M-19 in 1990, and the subsequent amnesty for its members. After full re-incorporation into civilian life, Petro was elected representative for Cundinamarca in 1991.
Three years later, Petro was appointed as to a diplomatic role in Belgium, under the Samper administration. The continuous death threats he received were an influential factor in his accepting the diplomatic post. Back in Colombia, and after an ill-fated attempt in the 1996 Bogotá mayoral election, Petro was once again elected representative in 1998. This time for the Bogotá constituency. It was during this second term in Congress, that Petro began to establish a reputation for being a thorn in the side of the Colombian political establishment.
Running, for Progresistas Petro won the 2011 Bogotá mayoral election defeating Enrique Peńalosa and Gina Parody.
From his time as a guerrilla it is known that he was known as the “Commander Aureliano” and was sentenced to 18 months in prison by military criminal justice. After laying down his arms, Petro turned to politics and held various positions, such as Representative to the Chamber for Cundinamarca, diplomatic attaché for Human Rights at the embassy in Belgium, senator and mayor of Bogotá (2012-2015).[νεκρός σύνδεσμος]
His passage through the mayor’s office of the Colombian capital caused enormous controversy. The Attorney General’s Office dismissed him and prohibited him from holding public office for 15 years for handling a crisis related to the garbage collection system. However, the Superior Court of Bogotá ordered his return in response to a ruling by the Inter-American Court of Human Rights. This fact catapulted him as the leader of the Colombian left.[νεκρός σύνδεσμος]
