Cicero's oration Pro Archia Poeta is the published literary form of his defense of Aulus Licinius Archias, a poet accused of not being a Roman citizen. The accusation is believed to have been a political move against Lucullus through Archias. The poet was originally Greek but had been living in Rome for an extended period of time. A letter from Cicero to Titus Pomponius Atticus in the year following the trial makes mention of Archias, but there is no conclusive evidence about the outcome of the trial. The oration was rediscovered in Liège by Petrarch in 1333.
Licinius Archias was born in Antioch around 120 BC and arrived in Rome in 102 BC. It was here that he earned a living as a poet and gained the patronage of the Roman general and politician L. Lucullus. Archias wrote poems of the general's military exploits, and in 93 BC, Lucullus helped him gain citizenship of the municipium of Heraclea. Thereafter, Archias was set up with a permanent residence in Rome in preparation for achieving full Roman citizenship. It was in Rome where Archias became a mentor and teacher of Cicero in his early education in rhetoric.
Archias had become eligible for Roman citizenship under the Lex Iulia de Civitate Latinis Danda, passed in 90 BC, and the Lex Plautia Papiria de Civitate Sociis Danda, passed in 89 BC. The Lex Iulia granted Roman citizenship to all citizens of municipia on the Italic peninsula, provided they had not fought against Rome in the Social War.
In 65 BC, the Roman Senate passed the Lex Papia de Peregrinis, which challenged false claims of citizenship and expelled foreigners from Rome. It is most likely under this law that Archias was prosecuted. Cicero came to his former teacher's defense at his trial in 62 BC, only months after delivering the famous Catiline Orations.
The prosecution laid out four accusations in its case against Archias:
