Real Audiencia of Buenos Aires

The Real Audiencia de Buenos Aires, were two audiencias, or highest courts, of the Spanish crown, which operated in Buenos Aires. The jurisdiction of the first covered the territory of the Governorate of the Río de la Plata and operated from 1661 to 1671. The second began to function in 1783 and had jurisdiction over the parts of the Viceroyalty of the Río de la Plata not covered by the Audiencia de Charcas, that is to say the intendancies of Buenos Aires, Córdoba del Tucumán, Salta del Tucumán and Paraguay. In 1810, after the May Revolution, it was suspended, and in 1813 the Assembly of the Year XIII permanently abolished it. The Audiencias operated in the city's cabildo building.
