On 6 September 1930, a military coup led by General José Félix Uriburu overthrew President Hipólito Yrigoyen. The coup marked the end of Argentina’s first democratic experiment under the Radical Civic Union. Uriburu’s government dissolved Congress and imposed authoritarian rule. The event began a long cycle of military interventions in national politics. It also reshaped political alliances and weakened democratic institutions. The coup remains a defining moment in Argentine political history.
