Marcus Licinius Crassus vs Nicias

Crassus, commanding eight legions, defeated the slave army led by Spartacus in Lucania. He crucified 6,000 captured slaves along the Appian Way. This victory restored Roman authority and earned Crassus political prestige, though Pompey claimed credit for ending the war.

Crassus served as censor, a high-ranking Roman magistrate responsible for conducting the census and supervising public morals. He attempted to enroll the Transpadane Gauls as Roman citizens and annex Egypt, but his colleague Quintus Lutatius Catulus opposed these measures, blocking them.

Crassus, Julius Caesar, and Pompey formed a secret political alliance to dominate Roman politics. The pact allowed Caesar to become consul and later governor of Gaul, while Crassus secured favorable legislation for his business interests and military command against Parthia.

Crassus invaded Parthia with seven legions but was defeated at Carrhae by Parthian general Surena. The Roman army was surrounded and destroyed by Parthian horse archers and cataphracts. Crassus was killed during negotiations, and his head was presented to the Parthian king.

Nicias opposed the aggressive policies of Cleon during the Battle of Pylos. When Cleon boasted he could capture the Spartan garrison, Nicias offered him the command. Cleon succeeded, boosting his popularity and undermining Nicias' position as a moderate leader.

Nicias negotiated a peace treaty with Sparta, ending the first phase of the Peloponnesian War. The treaty established a 50-year alliance between Athens and Sparta, but it was fragile and broke down within a few years. Nicias was the leading advocate for peace in Athens.

Nicias was appointed co-commander of the Athenian expedition to Sicily, despite his strong opposition to the campaign. He led the siege of Syracuse but was indecisive and failed to press advantages. The expedition became a disaster, with the entire Athenian force destroyed.

After the Athenian defeat at Syracuse, Nicias surrendered to the Syracusans. Despite his attempts to negotiate, he was executed by the Syracusans, along with his fellow commander Demosthenes. His death marked the end of the Sicilian Expedition and a major blow to Athens.
