Following a long period of exile, former Argentine president Juan Domingo Perón returned to Buenos Aires in June 1973, and his supporters gathered to welcome him at the Ezeiza airport. However, tensions were high among various factions within the Peronist movement, particularly between left-wing militants and more conservative elements supportive of the restoration of Perón’s rule. Prior to the arrival, rumors of potential violence circulated, leading to significant security concerns among the organizers of the welcoming event. As thousands of enthusiastic supporters gathered, snipers, likely from the opposing factions, opened fire on the crowd, creating chaos and panic as people fled for their lives. The initial attack resulted in a tragic toll, with at least 13 individuals reported dead and more than 300 others injured. Amidst the chaos, medical personnel and bystanders rushed to help the wounded, while political leaders scrambled to contain the fallout. The government led by then-President Héctor Cámpora found itself in a precarious situation, as the massacre embodied the divisions within the Peronist movement and highlighted broader societal unrest. The Ezeiza Massacre signified a turning point that would exacerbate political tensions in Argentina, leading to increased violence and the eventual rise of military rule in the years to follow.
