The death of Charlemagne’s son Emperor Louis the Pious starts a good old Frankish habit. Breaking up empires to equally share it to a emperor’s sons. Cologne or rather the political leadership of Cologne, Archbishop Gunthar plays a key role in the middle of the 9th century.
The Frankish Empire is in turmoil. After the death of Charlemagne’s only surviving son Louis the Pious the once mighty unified Frankish Empire dissolves into separate countries. In the long term two of these would be France and Germany. Cologne’s Archbishop Gunthar has a major role in that Frankish double divorce drama.

Sadly, there are no pictures or paintings of these historical, yet important figures for our episode. Most of the episode is about power politics, intrigues and power struggles. So sadly, for this companion post, there is not much that I can present you here.
A very complex time in regional history. The formation of political boundaries is fascinating.
