The Haymarket Square Riot
The riot in Pompeii, which occurred in 59 AD, was primarily triggered by a violent clash between local Pompeians and visitors from the nearby town of Nuceria during a gladiatorial games event. Tensions had been building due to longstanding rivalries, and the situation escalated into a full-blown riot, resulting in injuries and fatalities. The Roman authorities intervened, ultimately leading to a ban on such games in Pompeii for ten years as a means to restore order.
