On September 26, 1969 General Alfredo Ovando Candia, commander of Bolivia's armed forces, overthrew President Luis Adolfo Siles Salinas in a coup that installed a nationalist military government, part of the run of instability that made Bolivia one of the most coup-prone states in the world. Siles Salinas, a civilian, had become president in April 1969 on the death in office of General Rene Barrientos, under whom he had served as vice president. His hold was weak, and after only months Ovando, the armed forces commander who had shared power with Barrientos earlier in the decade, moved against him.
The coup deposed Siles Salinas without bloodshed, and Ovando took the presidency, pursuing a nationalist, reformist course that included nationalizing Gulf Oil's Bolivian holdings. Ovando's own tenure proved unstable: he was briefly overthrown in October 1970 before the leftist General Juan Jose Torres took power, who was in turn ousted by Hugo Banzer in 1971. Siles Salinas was removed and not physically harmed.

SOURCE REVIEWEDWikipedia, Luis Adolfo Siles Salinasopen source ↗
General Alfredo Ovando Candia, who had shared power with Rene Barrientos during the mid-1960s military governments, seized the presidency in September 1969 and pursued nationalist policies including the nationalization of Gulf Oil's Bolivian holdings, before his own overthrow in 1970.
Fate coding: Siles Salinas was deposed without bloodshed and not physically harmed, matching the dataset fate. Context: the coup is one link in Bolivia's exceptionally dense chain of coups (the country leads the world in coup attempts since 1950); Ovando's nationalist government nationalized Gulf Oil, and his own removal in October 1970, Torres's rise, and Banzer's 1971 coup are separate later dataset events. Note: some details of Ovando's earlier power-sharing with Barrientos are drawn from general biographical records; the core fact of the September 26, 1969 coup against Siles Salinas is confirmed by the list-of-coups record.
