For researchers and instructors of medieval European history, the Making of Charlemagne's Europe is a database of primary source material that provides insight into Europe under the rule of Charlemagne (768- 814 AD). This database, which was created by the Department of History and the Department of Digital Humanities at King's College London, has two main aims. The first is to "offer a single, unified database framework for the extraction of prosopographical and socio-economic data found in early medieval legal documents." The second is to "apply this framework to legal documents surviving from the reign of Charlemagne." This database provides information about over 4,000 charters, which visitors may browse by charter, agent (individuals and institutions involved in the charter), or places. For instance, in the browse by charter section, visitors can explore charters by filters such as transmission date and attribute/relationship type (e.g. "ecclesiastical offices and ranks" and "family relationship & kinship"). Researchers may want to start by reading Guide to Basic Queries, which is available on the site's homepage. Instructors may be interested in Early Medieval Charters: A Guide for Students, which provides a helpful overview of charters and their role in medieval Europe.
