1940 Bolivian general election

Since 1936, Bolivia had experienced a left-wing shift in government under the Military Socialist regimes of David Toro and Germán Busch. This period came to an end when Busch committed suicide on 23 August 1939, four months after dissolving the assembly and declaring himself dictator. Immediately following the death of Busch, the armed forces appointed General Carlos Quintanilla, the commander-in-chief of the army, to the office of president. Quintanilla soon set about reversing course on the more radical elements of the previous governments and returning the country to the conservative status quo prior to the Chaco War.

Though Quintanilla attempted to exercise a longer government, the prolonged indecision to call elections was met by opposition from the traditional political parties which sought to reassert themselves for the first time since the coup d'état which deposed them in 1936. Among the voices demanding elections was General Enrique Peñaranda who declared to the press that the country urgently needed "direct general elections to be called."[2] Finally, a group of representatives from the Liberal (PL), Genuine Republican (PRG), and Socialist Republican (PRG), parties addressed President Quintanilla with the warning that "Deferring for a longer time, without valid reasons, [...] the call for direct elections, will lead public opinion to the conviction that their participation in the electoral plebiscite will only serve to consolidate and legalize public powers [...] and that, therefore, will not be the authentic expression of the popular will."[2]

Given the pressure, Quintanilla put out the call on 6 October 1939, over a month after taking power, for new elections for president and vice president to be held on 10 March 1940.[3] However, only elections for president would occur as on 4 December 1939 the office of vice president was abolished in order to silence calls for Enrique Baldivieso, the former vice president to Germán Busch, to succeed to the presidency.[4]

To secure their chances at victory, the PL, PRG, and PRS consolidated into the Concordance electoral alliance.[5] General Enrique Peñaranda, one of the nearest approximations to a war hero produced by the Chaco War, was brought forth as the coalition's presidential candidate.[5] Peñaranda had been a member of the senior officer corps which after the Chaco War was forced to step aside in favor of the younger generation of officers represented by Germán Busch.

These young officers presented as their presidential candidate General Bernardino Bilbao Rioja, the new commander-in-chief of the army who represented the Military Socialist ideology of Toro and the deceased Busch.[6] Attempts by the mining oligarchy and the traditional parties to discredit Bilbao as a despot attempting to promulgate a leftist dictatorship were unsuccessful.[2] Faced with the possibility that Bilbao could conceivably win, the Quintanilla government summoned him to the government palace where he was beaten, gagged, and deported to Arica, Chile.[6] Though Bilbao's return was negotiated under threat of a military revolt from the young officers, he was sent directly from exile to London as a military attaché, removing him from circulation as a viable candidate.

As a result, Peñaranda's main electoral opposition came from José Antonio Arze. One of the primary sociologists and Marxist theorists in Bolivia, Arze had just that year returned from exile in Chile, having proven too far left even for the Military Socialist regime of David Toro which deported him in September 1936.[7] In April 1939, while still in Chile, Arze had formed the Bolivian Left Front (FIB), publishing a manifesto naming the FIB a union of the entire left-wing political spectrum. Despite this, the FIB maintained distinctly Marxist characteristics. For the 1940 elections, Arze ran as an independent as part of the FIB alliance.[8]
