Revolution of the Park in Buenos Aires forces Juárez Celman's resignation

Background. By 1889, Argentina faced a severe economic crisis marked by inflation, unemployment, and labor strikes. President Juárez Celman's administration, known as the "Unicato," was characterized by extreme centralization. Opposition forces organized in 1889, forming the Civic Union, which formally convened in April 1890. Senator Aristóbulo del Valle denounced clandestine currency emissions in May 1890, identifying them as a primary cause of the crisis's severity.

Uprising. The armed uprising began on July 26, 1890, with the takeover of the Buenos Aires Artillery Park. Rebel leaders controlled parts of the city for three days. Government forces, led by Vice President Carlos Pellegrini, assembled in Retiro to suppress the revolt. President Juárez Celman left for Córdoba, leaving repression to his subordinates. The capitulation was signed on July 29, 1890, at Palacio Miró.

Aftermath. Despite military defeat, the uprising achieved its political objective. Juárez Celman resigned on August 6, 1890, due to economic deterioration and political pressure. Carlos Pellegrini succeeded him as president, completing the term until October 12, 1892. The government granted amnesty to army members involved in the revolution. The Civic Union evolved into the Radical Civic Union, championing the principles of the 1890 uprising.
