Marcius Philippus was tribune of the plebs in 104 BCE, during which time he brought forward an agrarian law, of the details of which we are not informed, but which is chiefly memorable for the statement he made in recommending the measure, that there were not two thousand men in the state who possessed property.
He lost in a campaign for the consulship in 93 BCE to Marcus Herennius, but did reach the office in 91 BCE with Sextus Julius Caesar as his colleague.
He even became censor with Marcus Perperna in 86BCE and he is said to have expelled his own uncle Appius Claudius from the senate.
