The document discusses Peru's National Day of Criolla Music, which is celebrated on October 31 each year. It started in 1944 when the Peruvian government announced a special celebration of criolla music, which is a Peruvian genre that combines African, Spanish, and Andean influences. The most popular style of criolla music is the Marinera, said to be the national dance of Peru. The Spaniards founded their capital in Lima on the coast of Peru, where criolla culture took deepest root.
