The Diablada of Oruro goes back to the pre-Columbian period of the Urus who used to practice this dance in honour of the god Wari (also known as Huaricato or Huari). With the arrival of the Spanish conquerors and the evangelicalism, this divinity gradually personified the devil. The iconography depicted in the current suits, such as the snake, frog and ants, respond to the Uru mythology with the belief that if Wari wouldn't protect them they'd be destroyed by those creatures.
