From Ohio History Central
On April 11, 1993, Easter Sunday, approximately 450 prisoners in Cellblock L of the Southern Ohio Correctional Facility, in Lucasville, Ohio, rioted. The Southern Ohio Correctional Facility is a maximum security prison. The riot apparently occurred for several reasons. Chief among these reasons was a fear among Muslim inmates that correction officials would force the prisoners to have tuberculosis vaccinations. Taking these vaccinations would have violated the prisoners' faith. It also appears that some inmates desired to settle old disputes with other prisoners.
