The History Channel examines the Dark Ages from the fall of the Roman Empire to the First Crusade.

After the collapse of the Roman Empire, Western civilisation went into a state of decline which kickstarted the Dark Ages, the bleakest period in human history. This one-off History Channel documentary investigates this age of degeneration, which lasted close to 1000 years, between the fall of the world's greatest empire and ending in the resurgence of the Renaissance.—Tom Daly
