In Verrem ("Against Verres") is a series of speeches made by Cicero in 70 BC, during the corruption and extortion trial of Gaius Verres, the former governor of Sicily. The speeches, which were concurrent with Cicero's election to the aedileship, thrust Cicero into the public view.
During the Civil War between Marius and Sulla (88–87 BC), Verres had been a junior officer in a Marian legion under Gaius Papirius Carbo. He saw the tides of the war shifting to Sulla, and so, Cicero alleged, went over to Sulla's lines bearing his legion's paychest.
Afterwards, he was protected to a degree by Sulla, and allowed to indulge a skill for gubernatorial extortion in Cilicia under the province's governor, Gnaeus Cornelius Dolabella. By 73 BC he had been placed as governor of Sicily, one of the key grain-producing provinces of the Republic (Egypt at this time was still an independent Hellenistic kingdom). In Sicily, Verres was alleged to have despoiled temples and used a number of national emergencies, including the Third Servile War, as cover for elaborate extortion plots.
At the same time, Marcus Tullius Cicero was an up-and-coming political figure. After defending Sextus Roscius of Ameria in 80 BC on a highly politically charged case of parricide, Cicero left for a voyage to Greece and Rhodes. There, he learned a new and less-strenuous form of oratory from Molon of Rhodes before rushing back into the political arena upon Sulla's death. Cicero would serve in Sicily in 75 BC as a quaestor, and in doing so made contacts with a number of Sicilian towns. In fact a large amount of his clientele at the time came from Sicily, a link that would prove invaluable in 70 BC, when a deputation of Sicilians asked Cicero to level a prosecution against Verres for his alleged crimes on the island.
