Lucius Valerius Flaccus (consul 100 BC)

The earliest official capacity recorded for Lucius Flaccus is monetalis ("moneyer"), a common preliminary to the political career track for young men of senatorial rank.

Although no figures have survived from this census, Italians were registered as citizens in great numbers, presumably to strengthen the political power of those likely to support the Marian faction.

[3] Flaccus and Antonius expelled Marcus Duronius from the senate because as tribune he had abrogated a sumptuary law passed by Publius Licinius Crassus.

Lucius Flaccus was flamen Martialis[10] when he died, sometime after the cooptation of Julius Caesar to the pontifical college in 73 and before that of the Publius Sulpicius Galba who was praetor around 66.

[13] As princeps senatus and the oldest living consularis,[citation needed] Flaccus took the lead in attempting negotiations with Sulla, anticipating his return to Italy with troops after his peace settlement with Mithridates VI of Pontus in the fall of 85 BC.

[14] In an address to the senate, Flaccus urged concordia ("harmonious order") and took the initiative by sending envoys to Sulla in Greece.

In the meantime, Cinna and Carbo arranged to prolong their consulship for a second term in 84 by spinning Sulla's imminent return as a state of emergency, against which they also began to assemble troops.

[15] Flaccus was chosen in 82 BC by the senate – at the instigation of Sulla – as interrex, the official required for holding elections if for some reason the previous year's consuls were unable to do so.

Sulla sent a letter to Flaccus and the senate[16] in which he urged, given the chaotic state in which Rome found itself, that the appointment of a dictator would do more to restore order than the messy business of elections.
