L Appuleius Saturnius 104Bc Helmeted Roma Saturn Quadri

Lucius Appuleius Saturninus, (d. 100 bc), Roman politician who, with Gaius Servilius Glaucia, opposed the Roman Senate from 103 to 100, at first with the cooperation of the prominent general Gaius Marius.

Saturninus turned against the leaders of the Senate when, while serving as quaestor (financial administrator) at the port city of Ostia (probably in 105), he was stripped of his supervision of the grain supply by the leader of the Senate, Marcus Aemilius Scaurus. From 103 through 100 he used the office of tribune of the plebs (at the time, a position that reinforced popular sovereignty) to harass the Senate
