Soon after the end of the Chaco War in June 1935, local veterans' organizations began to be formed across the country, spanning the entire political and ideological spectrum.
Another group founded by Bolivian POWs in 1934 was the Reason for the Fatherland (Razón de Patria, RADEPA) military lodge which advocated internal reform within the army.
By that point, opposition to Toro had slowly increased amongst the young officers who believed that his pragmatic approach was not achieving meaningful political reforms they had hoped for.
In La Paz on 10 July 1937, the LEC elected Army Chief of the General Staff Germán Busch as the Supreme Leader (Jefe Supremo) of the organization.
However, his campaign for president in the 1940 general election proved too big a threat to traditional conservative interests, leading the interim government of Carlos Quintanilla to have him forcefully deported to Chile before being exiled as a military attaché in London.
