The Trojan War, which is traditionally considered to have occurred in the twelfth century bce, has been one of the most exploited subjects of European culture and history. Not only did it provide some of the most important literary motifs for ancient Greek and Roman culture, but it also played a role in the genesis of the nations of early medieval Europe. The Trojans had an afterlife that connected them to multitudes of subsequent peoples. This study examines the story of the Trojan origins of the Franks from its inception during the Merovingian period to its development under the Carolingians. Considering both textual and manuscript evidence, it discusses the dissemination of the origin story as well as its association with Charlemagne.
