1970 Chilean presidential election

Presidential elections were held in Chile on 4 September 1970. Salvador Allende of the Popular Unity alliance won a narrow plurality in a race against independent Jorge Alessandri and Christian Democrat Radomiro Tomic, before having his victory confirmed by a congressional vote after the Christian Democrats voted in favour of his candidacy.

Both the United States and the Soviet Union poured money into this election through their intelligence agencies and other sources, with the former attempting to sabotage Allende, and the latter supporting his campaign. Ambassador Edward Korry would play a major role in anti-Allende campaigns during the election.

Eduardo Frei Montalva and his Christian Democratic Party would later unite with Allende's opponents to form a congressional majority in an attempt to declare his presidency illegal in August 1973, catalyzing the military coup a few weeks later.
