Geoffroi de Villehardouin was a French knight and chronicler born around 1150. He is best known for his role in the Fourth Crusade, which took place from 1202 to 1204. Villehardouin served as a military leader and was one of the few who documented the events of the crusade, providing valuable insights into the motivations and actions of the participants. His most famous work is "La Conquête de Constantinople," where he details the capture of the city of Constantinople in 1204. This account is significant for its firsthand perspective on the crusade and the complexities of medieval warfare, as well as the interactions between Christians and Muslims.
