Unión Cívica
The Civic Union was a short-lived political party in Argentina, founded on April 13, 1890 out of the Civic Union of the Youth. That same year it led the Revolution of the Park that forced President Miguel Juárez Celman resignation, but shortly after dissolved itself in two branches, the Radical Civic Union and the National Civic Union, each following one of the Civic Union's foremost leaders, Leandro Alem and Bartolomé Mitre.
