It is the capital of Córdoba Province and the second most populous city in Argentina after Buenos Aires, with about 1.3 million inhabitants according to the 2010 census. It was founded on 6 July 1573 by Jerónimo Luis de Cabrera, who named it after Córdoba, Spain. It was one of the first Spanish colonial capitals of the region that is now Argentina (the oldest city is Santiago del Estero, founded in 1553).
