Maipo Department
Maipo Department is a former department of Chile. Its capital was the commune of Buin.
History
The department was created by president Domingo Santa María on 10 December 1883, with territory of the Rancagua Department. Simultaneously, the O'Higgins Province was created on such day.Beginning 1 February 1928, as the DFL 8582 entered into force, the department was incorporated into Santiago Province. Its territory was also modified, excluding El Monte, third district of the Valdivia de Paine subdelegation. In 1934, despite the restoration of O'Higgins Province, Maipo Department remained in Santiago Province.
The department was suppressed on 1 January 1976 as the "regionalización" entered into effect, during the military dictatorship of Pinochet. Its territory would form Maipo Province, within Santiago Metropolitan Region.
