On August 22, 1971 Colonel Hugo Banzer Suarez overthrew Bolivia's leftist president General Juan Jose Torres in a bloody, US-backed coup, ending Torres's ten-month experiment in socialist government and beginning Banzer's seven-year dictatorship, the Banzerato. Torres's leftward course, his Popular Assembly, and the earlier nationalization of Gulf Oil had alarmed conservative military officers and the Nixon administration. Banzer, an army officer with close US ties who had trained at US institutions and served as a military attache in Washington, had attempted a coup earlier in 1971 that failed, sending him briefly into exile in Argentina, but he did not abandon his ambitions.
In August 1971 he mounted a second, bloody uprising, backed by the Bolivian Socialist Falange and the Nationalist Revolutionary Movement and reportedly aided by the US, whose air force is said to have provided radio communications to the plotters. Torres, failing to arm his supporters or act forcefully, was quickly ousted and went into exile. Banzer imposed an authoritarian regime that arrested, tortured, and killed opponents; Torres himself was assassinated in exile in Argentina in 1976 during Operation Condor.

Hugo Banzer rose to power via a coup d'etat against socialist president Juan Jose Torres and repressed labor leaders, clergymen, indigenous people, and students during his 1971 to 1978 dictatorship known as the Banzerato, during which several thousand Bolivians sought asylum abroad, 3,000 political opponents were arrested, 200 were killed, and many more were tortured.
In early 1971 a faction of the Bolivian military attempted to unseat Torres but failed, whereupon Banzer fled to Argentina but did not give up his ambitions, and General Hugo Banzer Suarez, backed by American arms, military advisers, and field trainers, overthrew the Torres regime when Torres failed to provide the arms needed to resist the coup.
When the Bolivian military led by Hugo Banzer moved against the government, Juan Jose Torres failed to act forcefully and was quickly ousted, and the Banzer coup resulted in the takeover of the government by Bolivia's military and the beginning of an eight-year dictatorship.

When an attempted coup by rightist general Hugo Banzer was threatened by a breakdown in the plotters' radio communications, the US Air Force made their radio communications available to them, and though the first attempted takeover was crushed, Banzer was able to seize power by August of the following year in a bloody uprising, also with apparent US support.

Editorial Note
Arc closer: this August 22, 1971 coup CLOSES the Torres thread opened by his rise on October 7, 1970 (enriched in this batch), which in turn had followed Ovando's September 26, 1969 coup (batch 21); the trio of Ovando, Torres, and Banzer is a tight sequence. Fate coding: Torres was not physically harmed at the coup and went into exile, matching the dataset fate; his 1976 assassination in Argentina during Operation Condor is recorded as a separate later event, not folded into this record. Killings context: the broader Banzerato death toll (about 200 killed per human rights estimates cited by sources) is noted as the character of the regime that followed, attributed rather than asserted, and is distinct from the coup itself which sources call bloody without a settled figure. US role: the documented US provision of radio communications in the failed earlier attempt and apparent support for the August coup is stated as sourced.
