Following several years of military rule, Alejandro Agustín Lanusse was appointed president by the military junta in 1971. Under increasing political pressure for the return of democracy, Lanusse called for elections in 1973. Perón was banned from running but the Peronist party was allowed to participate. The presidential elections were won by Hector Cámpora, Perón's surrogate candidate. Dr. Héctor Cámpora, a left-wing Peronist, took office on 25 May 1973, and a month later in June, Perón had returned from Spain. One of Cámpora's first presidential actions was the granting of amnesty to members of terrorist organizations who had carried out political assassinations and terrorist attacks, and who had been tried and sentenced to prison by judges. Cámpora's months-long tenure in government was beset by political and social unrest. Over 600 social conflicts, strikes, and factory occupations took place within a single month. Even though far-left terrorist organisations had suspended their armed struggle, their joining with the participatory democracy process was interpreted as a direct threat by the Peronist right-wing faction.
