Charlemagne

Emperor Charlemagne was a French king who was crowned head of the Roman Empire. Charlemagne brought Europe out of the Dark Ages, restoring art and culture. According to the Tenth Doctor, his friendscalled him "Charlie."

In the year 800, Charlemagne held court in a castle in the Ardennes in Belgium. Attempts were made on the Emperor's life. One food taster died of mandrake poisoning. A feast was being prepared at the time of the Tenth Doctor's arrival for a pivotal meeting that afternoon with Pope Leo III that would make Charlemagne the Roman Emperor.

History was nearly derailed when Momus abducted Charlemagne from his carriage en route to his castle. On Planet 12 of the Ridion Alliance, Donna recognised a lot of the abducted dinner guests but had never heard of Charlemagne. The Doctor warned Charlemagne about the soup when he got back and told him he should treat the strange events as if they were a dream caused by too much cheese the previous night.
