King Charles VI of France (pictured) was nearly killed when several other dancers' costumes caught fire during a masquerade ball in Paris.

Charles VI, nicknamed the Beloved and in the 19th century, the Mad, was King of France from 1380 until his death in 1422. He is known for his mental illness and psychotic episodes that plagued him throughout his life.

The Bal des Ardents, or the Bal des Sauvages, was a masquerade ball held on 28 January 1393 in Paris, France, at which King Charles VI had a dance performance with five members of the French nobility. Four of the dancers were killed in a fire caused by a torch brought in by Louis I, Duke of Orléans, the king's brother.

A masquerade ball is a special kind of formal ball which many participants attend in costume wearing masks. Less formal "costume parties" may be a descendant of this tradition. A masquerade ball usually encompasses music and dancing. These nighttime events are used for entertainment and celebrations.
