This is the story of the fall of an Empire – and the rise of another.

Who spread Christianity, how, and why? In her quest to find the answer, Professor Alice Roberts takes us on a gripping investigative journey. From a secluded valley in south Wales to the shores of Brittany; from the heart of the Roman Empire in a time of political turmoil to the ancient city of Corinth in the footsteps of the apostle Paul; from Alexandria in the fourth century to Constantinople.

As the Roman Empire crumbled in Western Europe, a shadow of power remained, almost perfectly mapping onto its disappearing territories. And then, it continued to spread. Unearthing the archaeological clues and challenging long-established histories, Professor Roberts tells a remarkable story about the relationship between the Roman Empire and Christianity.

Lifting the veil on secrets that have been hidden in plain sight, this story is nothing short of astonishing.

Domination is a page-turning exploration of power and its survival.
