The work of Frédéric Cheyette Ermengard of Narbonne and the world of the troubadours, examines the life of Ermengard (1130-1196) through the study of sixty -four documents which bear his name. The book focused on the city of Narbonne and the Occitanie region as a whole, which had not been studied until later, during the Albigensian Crusade. This area received a lot of attention because there are more sources and because it was not a biography in which Ermengard was reconstructed beyond what the sources have to say about her. :There are many archival sources used that have worked together to build a rich description of the region. The focus was on love poetry, which he analyzed through the lens of a historian to see the role that poetry played and what it said about the society that created it. He was against the overinterpretation of this poetry that many have done, especially those who use the prism of literary analysis. The book was divided into four parts. There was the section on the social, dynastic and economic composition of the region. From there, the book focused on how this power worked in a court of law. Cheyetted examined how individual members of the court acted and how their power relationships functioned. The next part focuses on the idea of ​​a culture of loyalty through the study of oaths and poetry. In the final part, the political events from 1162 to 1196 become the central focus. Here, the dynastic struggles within these wars are at the center. Cheyette continued the work of his chapter in Aristocratic Women, looking again at the troubadours here, he showed here in even more detail his argument about the use of the language of love. Here he showed that love was used to describe oaths, agreements and honor, focusing on...... middle of paper ...... a role played by women. One of the many examples Cheyette gave of the importance of women was how oath takers were identified by their mothers. Another claim that Cheyette seemed to make was that this was not an insignificant region, filled with these radical, heretical Cathars. Instead, Cheyette posits that the Albigensian Crusade was provoked by Raymond's power play and Pope Innocent III's plan to pit different powers against each other. There were Cathars there, but their beliefs were tolerated even after the crusade. Cheyette thus maintains that the crusade was not provoked by religion, but by political maneuvering for power. He also opposes the idea that Occitania was a region where there was little. This book detailed the urban centers, rich culture and economy, although it was not a unified state there was a lot going on within the region..
