Ovando's coup belonged to a trend of military regimes of nationalist and progressive orientation in Latin America, represented by Juan Velasco Alvarado and Omar Torrijos Herrera.

On November 4, 1964, generals René Barrientos Ortuño and Alfredo Ovando Candía overthrew Víctor Paz Estenssoro and formed a military junta.

[6] The civilian government of Siles Salinas was born without any solid political base and lacked independence from the Armed Forces, which limited much of the president's actions.

Prior to this action, it is believed that Ovando had studied the Peruvian military regime headed by Juan Velasco Alvarado, admiring his authoritarian and nationalist model.

[13] Siles Salinas, who was visiting Santa Cruz de la Sierra, was sent into exile boarding a plane to Arica, Chile.

"[14] The revolutionary junta appointed Alfredo Ovando Candía as President of the Republic and Juan José Torres as Commander of the Armed Forces.

The manifesto was written by Juan José Torres and signed by officers Rogelio Miranda, David Lafuente Soto and Admiral Alberto Albarracín.

[6] It was a "nationalist and revolutionary" program, which meant the resumption of ideals of the Bolivian National Revolution and the reflection of the influence of the Peruanismo of Juan Velasco Alvarado.

[16] On October 17, President Ovando by Supreme Decree 08956 issued the revocation of all concessions of the Gulf Oil Company, active in Bolivia since 1956.

The nationalization of Gulf was planned by the minister of mines and oil Marcelo Quiroga Santa Cruz and supported by the commander Juan José Torres, who sent troops to occupy the facilities.
