The Revolution of the Park (Revolución del Parque), also known as the Revolution of '90, is an uprising against the national government of Argentina that takes place on July 26, 1890, and starts with the takeover of the Buenos Aires Artillery Park.
It is led by members of the Civic Union (which will later give rise to the modern Radical Civic Union) against the presidency of Miguel Juárez Celman (of the National Autonomist Party).
Though it fails in its main goals, the revolution forces Juárez Celman's resignation and marks the decline of the elite of the Generation of '80.
