Diplomatarium Ileburgense: Urkunden-Sammlung zur Geschichte u. Genealogie d. Grafen zu Eulenburg

The Diplomatarium Ileburgense was compiled by George Adalbert von Mülverstedt in the late 19th century as a comprehensive effort to document the history and genealogy of the noble house of Eulenburg. Published in Magdeburg, the volume serves as a critical reference work for historians, bringing together a vast collection of primary source documents, deeds, and charters that trace the lineage and land holdings of the family throughout the medieval and early modern periods.

Mülverstedt, a noted archivist and researcher of Prussian nobility, approached the work with the meticulous standards of 19th-century German historiography. His aim was to provide a definitive repository for researchers interested in the political and social influence of the Eulenburgs. The volume is esteemed by genealogists and scholars of regional German history for its rigorous transcription of records that might otherwise have remained scattered or inaccessible in private archives.
