Both Augur and his relative Quintus Mucius Scaevola Pontifex, father-in-law of Pompey, were prominent Optimates.
[1] Scaevola was made tribune in 128 BC, aedile in 125, and praetor in 121, in which capacity he acted as governor of Asia.
Upon his return to Rome the following year he faced a charge of extortion brought by Titus Albucius (probably on personal grounds) which he successfully defended.
[2][3] In 88 BC, he alone defended Gaius Marius against Sulla's motion to have him named an enemy of the people, saying that he would never agree to have this done to a man who had saved Rome.
Scaevola's daughter married Lucius Licinius Crassus, consul in 95 BC and the greatest orator of his day.
