Listeners and students have asked me who my favorite Roman emperor is. Lists of the "best" emperors often highlight giants like Augustus, Trajan, and Marcus Aurelius—undeniably impressive for their conquests and governance. But my favorite, for personal reasons, is a man overlooked by many historians and dismissed by the writers of his time. A blue-blooded elite, he seized power in a chaotic coup, faced senatorial scorn, yet ruled effectively. He expanded the empire, improved infrastructure, and, remarkably, seemed to enjoy himself while doing it. Who is this underappreciated emperor? Check out the episode to find out.
