This mestizo dance is also dramatized as a “Catholic Story”. It is a story of devils, enclosing a mystic plot supported by traditional belief, the eternal struggle between good and evil, a fight to the death between the devil’s legion and Archangel Michael, who bestowed peace on everyone with kindness and beauty. Once defeated, the devils stopped their fighting and there was Peace on the Earth, stamping out discord, evil and rage.

It starts with a dialogue between two powerful Angels, one represents harmony (Michael) and the other represents discontent and bitterness (Lucifer). The meeting takes place right on the limit of Hell, and then the Diablada bursts in warlike attitude. At the call of Archangel Michael, heavenly legions arrive and the first battle starts, which is won by the devils, who invade the Earth to exterminate Christianity; then the second battle takes place and the mortals are awaiting frightened for the outcome.

When the battle is over, the devils are defeated and they must suffer the shame of confessing their sins, "The Seven Deadly Sins", to the Holy Light.

As described above, the Diablada is the devil’s dance that was created by the miners and which represents the pagan-religious symbiosis of respect to the “Uncle” or Devil (lord of the tunnels and shafts) and devotion to the Virgin Candelaria, Patron Saint of the Miners. Its choreography represents the struggle between good and evil and the defeat of the seven deadly sins.

This dance is performed in all the artistic and folk expressions of Bolivia and particularly in Oruro during the Carnival time.
