The Ku Klux Klan (KKK) terrorizes the University of Dayton, a Catholic Institution, by exploding 12 bombs throughout the campus and setting on fire an 8-foot cross.
Several hundred Klansmen were routed by hundreds of neighborhood residents who joined students in chasing them off. The growing Catholic presence in Dayton during the 1920s drew the hostility of the Ku Klux Klan. More about the attack - More about the KKK
