The Broad Street Riot occurs in Boston, fueled by ethnic tensions between Yankees and Irish.
The Broad Street Riot was a massive brawl that occurred in Boston, Massachusetts, on June 11, 1837, between Irish Americans and Yankee firefighters. An estimated 800 people were involved in the actual fighting, with at least 10,000 spectators egging them on. Nearby homes were sacked and vandalized, and the occupants beaten. Many on both sides were seriously injured, but no immediate deaths resulted from the violence. After raging for hours, the riot was quelled when Mayor Samuel Eliot called in the state militia.
In the wake of the riot, Boston's police and fire departments were established.
