The Viking raids in the Rhineland were part of a series of invasions of Francia by the Vikings that took place during the final decades of the 9th century. From the Rhineland, which can be regarded as the nucleus of Frankish culture, the Franks had previously conquered almost the whole of Central Europe and established a great empire.
During these raids, the Vikings plundered the ancient Roman cities of Cologne, Bonn, Xanten, Trier and also the imperial city of Aachen, in which Charlemagne was buried and on whose throne the Frankish kings were crowned in Aachen Cathedral. In addition to these cities, numerous monasteries were also destroyed, together with entire libraries in which collections of writings from several centuries had been preserved. This shook the essence of Frankish culture.
Similar raids affected the regions where the Vikings had originally settled: the British Isles, the Baltic Sea region, Russia and the Mediterranean region. Many inhabitants of the affected regions were carted off as slaves,[1] the Bukhara slave trade along the Volga trade route being a major trade of the vikings.[2]
