For centuries, Rome was one of the world's largest imperial powers, its influence spread across Europe, North Africa, and the Middle-East, its military force successfully fighting off attacks by the Parthians, Germans, Persians and Goths. Then came the definitive split, the Vandal sack of Rome, and the crumbling of the West from Empire into kingdoms first nominally under Imperial rule and then, one by one, beyond it.

Imperial Tragedy tells the story of Rome's gradual collapse. Full of palace intrigue, religious conflicts and military history, as well as details of the shifts in social, religious and political structures, Imperial Tragedy contests the idea that Rome fell due to external invasions. Instead, it focuses on how the choices and conditions of those living within the empire led to its fall. For it was not a single catastrophic moment that broke the Empire but a creeping process; by the time people understood that Rome had fallen, the west of the Empire had long since broken the Imperial yoke.
