In March of 1816, folllowing the defeat of Napoleon at Waterloo, that representatives of the various Argentine provinces met in Tucumán to discuss the future of their country. On July 9 the delegates met in the Bazán family home, now the Casa Histórica de la Independencia museum, to proclaim their independence from Spanish rule and the formation of the United Provinces of South America later the Provincias Unidas del Río de la Plata.
The house belonged to Tucuman mayor Diego Bazán y Figueroa and was built near the end of the 17th century with three interior courtyards.
