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 DemocratRadomiro Tomic. Allende's victory was confirmed by a contingent election after the Christian Democrats voted in favor of his candidacy.

Both the United States and the Soviet Union invested money into the election through their intelligence agencies and other sources. The US attempted to sabotage Allende's campaign while the Soviets supported him. US ambassador Edward M. Korry played a major role in anti-Allende campaigns during the election.

Eduardo Frei Montalva and his Christian Democratic Party later united 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.
