Opening up Carolingian history to a new generation, this book draws on recently translated primary sources to examine the collapse of an early medieval kingdom.

The Fall of a Carolingian Kingdom investigates how the first royal divorce scandal led to the collapse of a kingdom, changing the fate of medieval Europe. Through a set of annotated translations of key contemporary sources, the book presents the downfall of the Frankish middle kingdom Lotharingia as a case study in early medieval politics, equipping readers to develop their own independent interpretations.

The book tracks the twists and turns of the scandal as it unfolded over a crucial decade and a half in the ninth century. It pinpoints key decisions and traces their consequences, placing them in the wider context of Carolingian politics, as the heirs of the Frankish emperors Charlemagne and Louis the Pious struggled to master their legacies. Drawing on primary sources such as letters, material culture, and secret treaties, The Fall of a Carolingian Kingdom offers readers a sharply defined window onto one of the most dramatic episodes in Carolingian history, rich with insights into the workings of early medieval society.
