Cicero is the consul, and he successfully convinces the senate to peresecute Catilline. He is in the prime of his Career. he is awarded the pater patriae for his contributions to Rome.
Catiline is a traitor
Fast forward, Caeser has fully asserted control after a combination of maneuvers when Cicero was exiled and what not. Cicero now seldom goes to the city. While he is through his letters dissatisfied, he is retired. There is really nothing he can do to be against Caesar.
Julius Ceaser is assassinated. Cicero sees his window, and he comes back to Rome. He reenters the public and begins to try to politically maneuver the republic back on track. Politically he is one of the most powerful men in Rome at the time.
Antony's wealth and political prowess threatened the republic. Cicero and the rest of the liberators try to shift their support to Octavian. Octavian bamboozles him, and they form the triumvirate.
Sure I'll fight against Antony. (Psych hahaha)
Are you down for our support?
The hitlist is formed, and per Antony's request, Cicero's name is added. Cicero arrives at the beach ready to flee, but he is constantly filled with doubt. He debates staying. Eventually, his small party is caught, and he is killed.
Hey Bub!. Kill me right.
Cicero's hands and head is brought to Rome to be placed on the Rostra to be displayed. The symbolism that the hands and head that spoke so eloquently to save the republic is finally as dead as the things they tried to save.
