God of wine, festivity, fertility, and ritual madness. His cult included the Bacchanalia festivals. Roman equivalent of Dionysus, also identified with the Italian god Liber.
Bacchus is wine, theater, and ritual frenzy, the Latin face of Dionysus and also the partner of the older Italian god Liber. His worship could be civic and licensed, or it could scare the Senate. In 186 BCE the Bacchanalia were restricted after a famous investigation; Livy tells the crackdown as a story about foreign rites and Roman control.
Wine and the city
Festivals of Liber on March 17 (Liberalia) marked young men's coming of age as much as the vine. The god who loosens also initiates. Stage performance, masks, and the vine-staff belong to him because theater, like wine, is a permitted loss of ordinary self.
Twice-born, twice named
The Semele story travels with him: the child sewn in Jupiter's thigh, the wanderer spreading the vine. Italians had already been pouring wine for Liber. Bacchus is the name that lets those two currents occupy one altar, sometimes comfortably, sometimes under police watch.

Worship Practices
Boys often took the toga virilis at the Liberalia. The Senate's decree on the Bacchanalia in 186 BCE cut the mystery cells back after a moral panic. What remained in public was Liber's wine and theater, not an unregulated night cult.
