This tradition continued in the city of Oruro over the centuries, in 1789 with the tale of the Chiru Chiru the festivity had another transformation with the introduction of the tale of the Seven deadly sins written by the parish priest Ladislao Montealegre,[1] and with the Bolivian War of Independence the parade was moved to Carnival.[2] By the 19th century the tradition had profound roots with the mining and the devotion to the Virgin of Socavón and, as it was recorded in the newspapers of that time, the dancers made offerings to the feet of the Virgin after the parade. At the beginning it was considered a working class custom but by the ends of the 19th century and beginnings of the 20th century the tradition was popularized reaching all groups of the Oruro society.[34]
