Comando de Libertação Nacional

The Comando de Libertação Nacional (Colina, English: National Liberation Command) was a far left political organization in Brazil. It originated on 1967 in the state of Minas Gerais, through the merger of Worker's Politics (Portuguese: Política Operária - Polop), an organization founded in 1961 as a faction of the Brazilian Socialist Party, with some leftist militants. Colina embraced the ideas advocated by OSPAAAL, starting armed actions in 1968 to fund rural guerrilla warfare against the military dictatorship installed after the United States government-sponsored 1964 coup d'état.

Colina became known for its clumsy attempt to "make justice" against Bolivian Captain Gary Prado, billed as the officer who had captured and executed Che Guevara in Bolivia. On June 1, 1968, João Lucas Alves, Severino Viana, José Roberto Monteiro, and Amílcar Baiardi shot and killed an officer in the neighborhood of Gávea, Rio de Janeiro, believing he was the Bolivian officer, when in fact it was Edward Ernest Tito Otto Maximilian Von Westernhagen, a German Army Major. Given the misunderstanding, Colina refused to take responsibility for the attack. Baiardi, the only of the four militants who survived the dictatorship, revealed Colina's involvement in the attack on 1988.

On November 1968, João Lucas was arrested and tortured to death. Three months later, it was Severino that got captured. He was found dead in his cell under the allegation of "suicide". Such murder practice was common in the period, as the death of journalist Vladimir Herzog would later reveal.
