be given the cognomen Magnus, or "the Great", reportedly after Pompey's boyhood hero Alexander. Pompey then asked for a triumph to celebrate his victories, an unprecedented demand for someone so young, and who had yet to hold senior political office. Sulla denied his request but gave way when Pompey refused to disband his army until it was granted, although he tried to offset the impact by awarding triumphs to Lucius Murena and Gaius Flaccus. Pompey held his triumph on 12 March 80 BC, but it marked the end of the close relationship between the two men. Against Sulla's advice, Pompey supported Marcus Aemilius Lepidus in his bid to be elected consul for 78 BC, and was omitted from his will when the dictator died shortly after. Often cited as an example of Pompey's lack of political insight, as Sulla feared Lepidus now assumed leadership of the reformist populares movement. He also tried to block his state funeral, an act successfully opposed by Pompey and which signalled his claim to be Sulla's political heir. After his consulship expired at the beginning of 77 BC, Lepidus was made proconsul of Cisalpine and Transalpine Gaul, before his opponents in the Senate forced his recall. Since losing proconsular immunity left him open to prosecution and probable disgrace, Lepidus refused and was declared an enemy of the state. When he marched on Rome at the head of an army, the Senate passed a Consultum Ultimum, giving the interrex Appius Claudius and proconsul Catulus wide-ranging powers to "preserve public safety". One measure taken by Catulus and Claudius was to appoint Pompey a legate with propraetor powers. He quickly recruited troops from among his veterans in Picenum, and while Lepidus continued south, Pompey moved north to besiege Mutina in Cisalpine Gaul. The town was held by Marcus Junius Brutus, who surrendered after a lengthy siege, before being assassinated next day, allegedly on Pompey's orders. Catulus then defeated Lepidus outside Rome, while Pompey marched against his rear, catching him near Cosa. Lepidus and the remains of his army retreated to Sardinia, where he died. Sertorian War and first consulship Sertorian War The Sertorian War began in 80 BC when Quintus Sertorius initiated a rebellion in Hispania, where he was joined by other Marian survivors like Perpenna. Supported by local tribes, he took control of Hispania Citerior, then forced proconsul Metellus out of neighbouring Hispania Ulterior. Pompey asked the
