Award-winning historian Tom Holland recounts one of the most dazzling chapters in Roman history - the Pax Romana - when the Empire reached the heights of its predatory glory. The year 69AD was one of civil war, when four Caesars in succession ruled the Empire. But from the chaos emerged an era of unrivalled Roman peace and power. 

Guest: Tom Holland, historian and author of Pax: War and Peace in Rome's Golden Age. Co-host of The Rest is History podcast.
