Cicero's De re publica is a philosophical dialogue written in the 50s BC consisting of 6 books. It discusses the ideal form of government through conversations between Scipio Aemilianus and other Roman statesmen. The text was reconstructed in the 19th century from a medieval palimpsest that contained fragments of books 1-5. Each book covers different topics relating to political philosophy over the course of three days of discussion. Cicero ultimately argues that monarchy is the best form of government when led by a wise and just ruler.
