Josiah Osgood is a historian of Rome who researches the fall of the Roman Republic and the Roman Empire. His first book, Caesar’s Legacy (Cambridge University Press, 2006) explores the civil war that followed the assassination of Julius Caesar and its commemoration in literature. In subsequent books and articles Osgood has continued to look at political violence and civil war. Turia: A Roman Woman’s Civil War (Oxford University Press, 2014) tells the story of a woman of the first century BC who helped her family survive waves of unrest. His latest book brings to life the spectacle of Rome's criminal courts through the story of their greatest performer: Lawless Republic: The Rise of Cicero and the Decline of Rome (Basic Books, 2025). Professor Osgood has co-edited several volumes on Roman history, historiography, and literature. For Princeton University Press’ popular Ancient Wisdom for Modern Readers series, he has translated How to Be a Bad Emperor (Suetonius) and How to Stop a Conspiracy (Sallust). Osgood writes and speaks about the value of studying Classics in democracies today and has contributed to such outlets as The Washington Post, Time Magazine, Open Mind, and Medium as well as a number of podcasts.
