The term derives from Bacchus, the Roman equivalent of Dionysus, god of wine and intoxication.
[3] It is believed that Bacchanalian rituals first started in southern Italy and were introduced to Etruria and Rome.
Around 186 BC, the Roman Senate found out about those unofficial Bacchanalian rituals and launched a repressive campaign against it.
The women were returned to their families for private punishments, while the men were imprisoned or executed.
The Senatus auctoritas de Bacchanalibus decree was passed to forbid any future similar order.
