It was a time of revolution. The Roman Revolution describes the little known "crisis of the third century", and how it led to a revolutionary new Roman Empire. Long before the more famous collapse of the Western Roman Empire in the fifth century, in the years between AD 235-275, barbarian invasions, civil war, and plague devastated ancient Rome. Out of this ordeal came new leaders, new government, new armies, and a new vision of what it was to be Roman. Best remembered today is the rapid rise of Christianity in this period, as Rome's pagan gods were rejected, and the emperor Constantine converted to this new religion. Less well remembered is the plethora of other changes that conspired to provide an environment well suited to a religious revolution. Drawing on the latest research, Nick Holmes looks for new answers to old questions. He charts the rise of the Roman Republic and the classical Roman Empire, examining the roles played by sheer good luck and the benign climate. Focusing on the reigns of the critically important but under-researched emperors in the third century, such as Aurelian, Diocletian, and Constantine, he vividly brings to life how Rome just escaped catastrophe in the third century, and embarked on a journey that would take it into a brave new world--one which provided the foundations for modern Europe and America. Nick Holmes is an author, podcaster, and historian. His passion is Roman history. He is the author of a multi-volume series on the fall of the Roman Empire. It is intended to be the most comprehensive account of this momentous event since Edward Gibbon's legendary History of the Decline and Fall of the Roman Empire over two hundred years ago.
