Diplomata Belgica offers a critical survey of all the diplomatic sources, edited or still unpublished, and issued by both natural persons and legal bodies from the medieval Southern Low Countries. Diplomata Belgica covers present day Belgium as well as those areas which belonged historically to the Southern Low Countries but are part now of France (French Flanders, French Hainault), the Netherlands (parts of the provinces of Zeeland, Noord-Brabant, Limburg), the Grand Duchy of Luxembourg, or Germany (parts of the Rhineland). At this stage,Diplomata Belgica contains metadata about almost 35,000 charters and deeds in Latin, Old-French, Middle Dutch and Middle High German, almost 19,000 full text transcriptions and almost 5,000 photographs of original charters. The database aims at exhaustivity for the period before 1250 and will, in the future, also include late medieval diplomatic materials without striving after completeness.
