Regnum Francorum Online

Regnum Francorum Online: interactive maps and sources of early medieval Europe, is a geospatial database with the aim of referencing historical events of Late Antiquity and Early Medieval (western) Europe to evidence in source-documents, compiling meta-data about the events, such as time, space and agency, and visualizing the events on interactive maps. This far, meta-data about more than 14.000 events are maintained in the database and avilable for further temporal and spatial analysis. Short quotes from source documents, describing the properties of the events and their components, are also maintained in the database. The events are related to their evidence in source documents, of which a majority are available in digital libraries and databases around the internet, such as Monumenta Germania historica, Regesta Imperii, Gallica and Google Books, and other libraries. These sources are linked directly or can be embedded into the historical GIS system. This is enabled by unique and persistant identifiers of the sources and the possibility to even reference individual documents by page or number.
