New reference project: Organizational structure of the royal court of Wilhelm I.

A new version of the long-standing org chart of the Prussian court has been prepared by BBAW:

Organigramm des Hofstaats von Wilhelm I. In: Die Sprache der Monarchie, hg. v. Akademienvorhaben “Anpassungsstrategien der späten mitteleuropäischen Monarchie am preußischen Beispiel (1786-1918)”, Berlin-Brandenburgische Akademie der Wissenschaften, Berlin. Version 3 vom 03.12.2020. URL: https://actaborussica.bbaw.de/v3/P0009429

Interestingly, the organisational structure has been published in TEI XML, which is available for download at https://actaborussica.bbaw.de/api/v1/tei-xml.xql?id=P0009429.
