Among Romans, crucifixion originated as a deterrence against revolt of slaves, probably as early as 200 B.C.E. By Jesus's time, it was the primary form of punishment for "inciting rebellion" (i.e., treason or sedition) the exact crime which Jesus was charged.[..] The punishment applied solely to non-Roman citizens. Roman citizens could be crucified, however, if the crime was so grave that it essentially forfeited their citizenship.
