Each Monday, this column turns a page in history to explore the discoveries, events and people that continue to affect the history being made today.

Europe was mired in a centuries-long dark age before a king named Charlemagne came along and turned on the light switch.

Both a fierce warrior and in many ways the first Renaissance man, Charlemagne's achievements on the battlefield and in his laws led to the first notion of a pan-European identity.
