During the times of the Tahuantinsuyu, the four administrative entities known as suyus had their own representative dances during the Ito festival, a festivity once celebrated throughout the entire empire but, according to the historian José Mansilla Vázquez, who based on manuscripts of Fray Martín de Murúa, says that these festivities were outlawed during the Viceroyalty of Peru with the exception of Oruro which, for being considered an important miner city in the 16th century, counted with some privileges and the Spanish authorities looked to the other way allowing this festivity persist in this city, adapting itself later into the Spanish traditions between the Carnestolendas and the Corpus Christi becoming into the Carnaval of Oruro over the centuries.[15]
