De Dictatura Pompei (On the Dictatorship of Pompey), opposing demands for Pompey to be made dictator, writing "it is better to rule no one than to be another man's slave, for one can live honourably without power but to live as a slave is impossible". He was in this episode more radical than Cato the Younger, who supported Pompey's elevation as sole consul for 52, saying "any government at all is better than no government". Soon after Pompey was made sole consul, Pompey passed the lex Pompeia de vi, which targeted Titus Annius Milo, for which Cicero would write a speech pro Milone. Brutus also wrote for Milo, writing (a now lost) pro T Annio Milone, in which he connected Milo's killing of Clodius explicitly to the welfare of the state and possibly also criticising what he saw as Pompey's abuses of power. This speech or pamphlet was very well received and positively viewed by later teachers of rhetoric. In the late 50s, Brutus was elected as a pontifex, one of the public priests in charge of supervising the calendar and maintaining Rome's peaceful relationship with the gods. It is likely that Caesar supported his election. Caesar had previously invited Brutus, after his quaestorship, to join him as a legate in Gaul, but Brutus declined, instead going with Appius Pulcher to Cilicia, possibly out of loyalty thereto. During the 50s, Brutus also was involved in some major trials, working alongside famous advocates like Cicero and Quintus Hortensius. In 50, he – with Pompey and Hortensius – played a significant role in defending Brutus' father-in-law Appius Claudius from charges of treason and electoral malpractice. In the political crisis running up to Caesar's Civil War in 49, Brutus' views are mostly unknown. While he did oppose Pompey until 52, Brutus may have simply taken a tactical silence. Caesar's civil war When Caesar's Civil War broke out in January 49 BC between Pompey and Caesar, Brutus had a choice whether to support Pompey, whom the senate supported, or to join his mother's lover Caesar, who also promised vengeance for Brutus' father's death. Pompey and his allies fled the city before Caesar's army arrived in March. Brutus decided to support his father's killer, Pompey; this choice may have had mostly to do with Brutus' closest allies – Appius Claudius, Cato, Cicero, etc. – also all joining Pompey. He did not, however, immediately join Pompey,
