Events

By place

Roman Republic

• Consuls: Lucius Valerius Flaccus, Gaius Marius (Marius's sixth consulship).
• Manius Aquillius celebrates an ovation for victories in the Second Servile War.
• Lucius Appuleius Saturninus, a tribune, passes a law to redistribute land to military veterans. The law requires that all senators swear to abide by it. Quintus Caecilus Metellus Numidicus refuses and is exiled. He goes to Rhodes to study philosophy.
• Late summer–autumn: Saturninus stands for tribune again for the following year, and is elected. His associate, the praetor Gaius Servilius Glaucia, attempts to stand for the consulship (illegally, as praetors cannot immediately become consul). A rival candidate, Gaius Memmius, is found murdered by agents of Saturninus and Glaucia, who are declared public enemies by the Senate. The Senate issues the senatus consultum ultimum, and Marius, as consul, defeats his former ally in battle in the Forum. Saturninus and his followers surrender on condition that their lives are spared, but they are stoned to death with roof tiles in the Curia Hostilia by renegade senators.
• The building of the Sanctuary of Fortuna Primigenia, Palestrina, Italy, is begun. The model of it is now kept at the Museo Archeologico Nazionale, Italy (approximate date).
