In the fourth episode of the series, Clovis was the first Frankish king to acknowledge the Christian faith. This changed the direction of Europe's history.

Join us on an unforgettable voyage through one of the most desolate periods in human history as the rulers, conflicts, and cataclysmic societal breakdown of Early Middle Ages are brought to light. At its height in the second century A.D., the Roman Empire was the beacon of learning, trade, power and prosperity in the western world. But the once-powerful Rome--rotten to the core by the fifth century--lay open to barbarian warriors who came in wave after wave of invasion, slaughtering, stealing, and ultimately, settling. As chaos replaced culture, Europe was beset by famine, plague, persecutions, and a state of war that was so persistent it was only rarely interrupted by peace.
The documentary profiles those who battled to shape the future, from the warlords whose armies threatened to case the demise of European society, like Alaric, Charles the Hammer, and Clovis; to the men and women who valiantly tended the flames of justice, knowledge, and innovation including Charlemagne, St. Benedict, Empress Theodora, and other brave souls who fought for peace and enlightenment. It was in the shadows of this turbulent millennium that the seeds of modern civilization were sown.
