Royal Audiencia of Buenos Aires
The Real Audiencia de Buenos Aires, were two audiencias, or highest courts, of the Spanish crown, which resided in Buenos Aires. The authority of the first extended to 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 as its territory the areas 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 disbanded it. The Audiencias resided in the city's cabildo building.
