Lucius Licinius Crassus
This affair drove Scaurus to support the legal reforms of Marcus Livius Drusus to enlarge the senate by adding around 300 "equites" and transfer the court jury pools back from the "equites" into the senate. Scaurus was one of Drusus' main advisors. Alongside Lucius Licinius Crassus, Scaurus was Drusus' main conservative champion and helped pass his extensive legislative programme. However, after the sudden death of Crassus in September 91 BC, Drusus rapidly lost his support in the senate, and the consul Lucius Marcius Philippus succeeded in abrogating Drusus' laws on religious technicalities.
