My bad, it was Marius that Cesar was related to.It was all very incestuous. In the late republic, you had to be of senatorial rank and from a senatorial aristocracy family to command an army or get other mega-power / mega-graft goodies. So factions competed to nominate their members for positions with clout. So your faction would try to get you an army command, so you could collect your army in Gaul or Syria and then come back with it to Rome and murder the senators in the other factions - who would nominate their guy to an equally powerful army command somewhere else with the same purpose in mind.
It's astonishing that Rome lasted so long. The Civil Wars never really stopped.
Caesar's uncle Gaius Marius was a popularis, Marius' protégé Lucius Cornelius Sulla was an optimas, and in Caesar's youth their rivalry led to civil war. [wikipedia]
lol that same Marius of the Marius Reforms.
Gaius Marius (Latin: [ˈɡaːijʊs ˈmarijʊs]; c. 157 BC – 13 January 86 BC) was a Roman general and statesman. Victor of the Cimbricand Jugurthine wars, he held the office of consul an unprecedented seven times during his career. He was also noted for his important reforms of Roman armies. He was at the centre of a paradigmatic shift from the militia levies of the middle Republic to the professional soldiery of the late Republic; he also improved the pilum, a javelin, and made large-scale changes to the logistical structure of the Roman army.[1]
