Who is Cicero from The Jugurthine War and what is their importance?

Cicero is Caitline's main enemy. The Roman's elect him as a consular in preference to Catiline. Consequently, Catiline attempts to assassinate him, but the government foils his plans. Cicero then organizes the capture of Volturcius as he makes his way back from a meeting with the Gauls. Cicero takes Volturcius in front of the Senate, and they force a confession from him. From his confession, they discover Catiline's plans to march into Rome and destroy the city. While Antonio marches out to confront Catiline, the senate asks Cicero to stay in Rome and protect the city. His leadership is a major factor in Catiline's defeat.
