Quintus Tullius Cicero

Quintus Tullius Cicero (c. 102–43 BC) was the younger brother of Marcus Tullius Cicero. He served as praetor, governed Asia, and was one of Caesar's legates in Gaul and Britain. He was proscribed and killed along with his brother in 43 BC.

The Commentariolum Petitionis (Short Guide to Electioneering) is a practical handbook of Roman electoral politics. It covers how to build a coalition, manage different social classes, and present oneself to voters. Whether Quintus actually wrote it is debated, but it is the most detailed surviving account of how Roman elections actually worked — not constitutional theory but the practical mechanics of canvassing, patronage, and persuasion.
