Late 20th century

Twelve years of tumultuous rule left the MNR divided. In 1964, a military junta overthrew President Estenssoro at the outset of his third term. The 1969 death of President René Barrientos Ortuño, a former member of the junta who was elected president in 1966, led to a succession of weak governments. Alarmed by the rising Popular Assembly and the increase in the popularity of President Juan José Torres, the military, the MNR, and others installed Colonel (later General) Hugo Banzer Suárez as president in 1971. He returned to the presidency in 1997 through 2001. Juan José Torres, who had fled Bolivia, was kidnapped and assassinated in 1976 as part of Operation Condor, the U.S.-supported campaign of political repression by South American right-wing dictators.

The United States' Central Intelligence Agency (CIA) financed and trained the Bolivian military dictatorship in the 1960s. The revolutionary leader Che Guevara was killed by a team of CIA officers and members of the Bolivian Army on 9 October 1967, in Bolivia. Félix Rodríguez was a CIA officer on the team with the Bolivian Army that captured and shot Guevara. Rodriguez said that after he received a Bolivian presidential execution order, he told "the soldier who pulled the trigger to aim carefully, to remain consistent with the Bolivian government's story that Che had been killed in action during a clash with the Bolivian army." Rodriguez said the US government had wanted Che in Panama, and "I could have tried to falsify the command to the troops, and got Che to Panama as the US government said they had wanted", but that he had chosen to "let history run its course" as desired by Bolivia.

Elections in 1979 and 1981 were inconclusive and marked by fraud. There were coups d'état, counter-coups, and caretaker governments. In 1980, General Luis García Meza Tejada carried out a ruthless and violent coup d'état that did not have popular support. The Bolivian Workers' Center, which tried to resist the putsch, was violently repressed. More than a thousand people were killed in less than a year. Cousin of one of the most important narco-trafficker of the country, Luis García Meza Tejada favors the production of cocaine. He pacified the people by promising to remain in power only for one year. At the end of the year, he staged a televised rally to claim popular support and announced, " Bueno, me quedo ", or, "All right; I'll stay ". After a military rebellion forced out Meza in 1981, three other military governments in 14 months struggled with Bolivia's growing problems. Unrest forced the military to convoke the Congress, elected in 1980, and allow it to choose a new chief executive. In October 1982, Hernán Siles Zuazo again became president, 22 years after the end of his first term of office (1956–1960).
