The Ezeiza massacre took place on June 20, 1973 near the Ezeiza International Airport in Buenos Aires, Argentina. Peronist masses, including many young people, had gathered there to acclaim Juan Perón's definitive return from an 18-year exile in Spain. The police estimated three and a half million people. In his plane, Perón was accompanied by El Tío ("Uncle") president Héctor Cámpora, representative of the Peronists' left wing, who had come to power on May 25, 1973, amid popular euphoria and a period of political turmoil.
