It is thought that the name Tucumán derives from the quechua Yucuman, that means "place where rivers are born".
The city was founded under the protection of Saint San Miguel Arcángel on May 31, 1565 by Diego de Villarroel, originally at the extreme portion of the Portugués Plateau on the lands of Ibatín, but due to bad water quality and harassment by the calchaquí indigenous population, it was moved to its present location in 1685 at that time named "La Toma", located at the right bank of Salí River.
In 2000 it was declared historical city, both for its architectonic and urban patrimony, and for its outstanding role in our national history. On July 9, 1816, a Congressional meeting held in this city declared the independence from Spain. Such emancipation action took place in the so–called Casa de la Independencia (House of the Independence), widely known as Casa de Tucumán (Tucumán House).
In Tucumán there are the National University of Tucumán (founded in 1914), the National Technological University (founded in 1954), the Northern University Santo Tomás de Aquino and the Lillo Institute, devoted to biological research.
