Spartacus ( ; 111–71 BC) was a Thracian gladiator who, along with the Gauls Crixus, Oenomaus, Castus and Gannicus, was one of the escaped slave leaders in the Third Servile War, a major slave uprising against the Roman Republic. Little is known about Spartacus beyond the events of the war, and surviving historical accounts are sometimes contradictory and may not always be reliable. However, all sources agree that he was a former gladiator and an accomplished military leader.
