The main contribution of CALOSEMA beyond the state of the art has been the creation, for the first time, of a complete corpus of Lombard documentation between the years 774-924 and its implementation in a database which content every single item related to social and political complexity – i.e. aristocratic residences, spaces for assemblies, judicial proceedings, monasteries and churches, political territories, the name of aristocracies (both lay and ecclesiastic), local officials and local priests etc. –, which allows us strenghten our knowledge about the documentary collection from early medieval Lombardy, completing the first attempt, which was done at the end of the 19th century. The database created by the CALOSEMA project allows, for the first time, to study all the Lombard early mediedal written sources, consenting, at the same time, the most coherent study of political power and social articulation of the northern Italian Kingdom of Italy in the Early Middle Ages (for it I've benefited for a short visit within the IGIER institut of the Università Bocconi, in Milan).
The comparative approach of CALOSEMA has permited other innovative aspects of the research. In fact, for decades, the study of the Early Middle Ages was undertaken by different scientific communities that did not necessarily interact with each other. Even nowadays some research agendas around the Early Medieval World are marked by strong national historiographical tendencies, such as the process of “Reconquista” in Christian Spain, the emergence of a strong central power in England and the end of the Carolingian world in Central Europe, among others. Equally revealing is the quite limited interaction between historians and archaeologists. CALOSEMA has been able to do a broad-base study throughout the combined use of a comparative method and a critical study of a wide body of information (written sources and material record) to understand the political complexity of two Southern European areas, developing a social theory which would overcome traditional interpretations, based on the (separate) reading of the written and archaeological sources, and on hypotheses built from a single case study, very often limited to the narrow margins of national states from Italy and Spain
