Bloody Monday was August 6, 1855, in Louisville, Kentucky, an election day, when Protestant mobs attacked German and Irish Catholic neighborhoods. These riots grew out of the bitter rivalry between the Democrats and the nativist Know-Nothing Party. Multiple street fights raged, leaving twenty-two people dead, scores were injured, and much property was destroyed by fire. Five people were later indicted, but none were convicted, and the victims were not compensated.
