The Revolution of the Park (Revolución del Parque), also known as the Revolution of 1890 or Revolution of '90, was a civic-military uprising against the national government of Argentina that took place from July 26 to 29, 1890. The revolution began with the takeover of the Buenos Aires Artillery Park (Parque de Artillería), located in what is today Lavalle Square. Led by the recently formed Civic Union against the presidency of Miguel Juárez Celman of the National Autonomist Party, the uprising was militarily defeated but achieved its political objective: Celman's resignation on August 6, 1890. The revolution marked a turning point in Argentine political history and led to the eventual formation of the Radical Civic Union.
