Cologne in the 11th century: We look around a bit in the area of Cologne Cathedral, where the Archbishop's palace is located, the monastery monastery and on the square itself, where court hearings took place.

Heribert is also one of the most important medieval archbishops in the history of Cologne and here you can find out why this 11th century imperial prince is so significant for Cologne's development

Cologne in the Year 1000 AD. This year was a year like many others. But let's take advantage of the beginning of the new millennium to discover the city on foot again.

How did the young Byzantine princess Theophanu become the richest woman in Europe at only 12 years old at the end of the 10th century? And how did she become the most powerful woman in Europe at the age of 24, with far-reaching effects on European history? In this episode, we will look at her breathtaking life and, of course, at the end, what all this actually has to do with Cologne itself.

Cologne in the middle of the 10th century. The largest city of medieval Germany just before the turn of the millennium. The city is experiencing a tremendous boom. Economic development, church building and a direct line to the emperor make this possible. Archbishop Bruno of Cologne, brother of Emperor Otto I, was behind this. We talk about his work in this episode.

Cologne's Frankish era is often overlooked. Yet this period was just as long as the Roman era. A whole 500 years! You can look back, but of course you can also look forward.

Cologne becomes the starting point of the so-called imperial church system that forms in eastern France in the middle of the 10th century. The little brother of Emperor Otto I, also called Otto the Great, becomes a big guy himself when he is elected Archbishop of Cologne in 953 and at the same time appointed Duke of Lorraine. As archduke, Bruno thus has more power than anyone else in the empire. With the exception of his big brother. What effects will this have for Cologne?

Cologne is in an intermediate phase around the year 900. In the whole region of the former Frankish Middle Kingdom of Lothar the question is going around, which empire can protect it better? To which sub-kingdom of Charles the Great's former Frankish empire do people feel more attached? The West Frankish Empire, which later became France? Or to the Eastern Frankish Empire, which later becomes the Holy Roman Empire and the Kingdom of Germany?

Only recently, the Vikings sacked Cologne in 881. While the people of Cologne are still busy rebuilding, new dangers are already approaching. The Magyars, also known as the Hungarians, are attacking the East Frankish Empire like the Huns in late antiquity. But it is not all bad at this time. Monastic life flourished and even minted coins designating Cologne as holy testify to the city's upswing here at the end of the early Middle Ages.

Cologne and the Rhineland at the end of the 9th century. For quite some time, the various heirs of the once great but now fragmented Frankish Empire have been fighting each other. The Vikings take advantage of this political instability and plunder the rich Rhineland, the heart of the Frankish Empire.
