The Codex Germaniae diplomaticus was compiled by Johann Christian Lünig, a prolific German jurist and archivist of the early 18th century. Published during an era defined by the formalization of Germanic legal history, the work was designed to serve as a comprehensive repository of essential state documents. Lünig intended the collection to supplement existing archival records, specifically addressing gaps in previous publications like the Teutschen Reichs-Archiv by providing scholars and legal practitioners with primary sources necessary for the study of imperial history and public law.

Lünig’s approach reflected the Enlightenment-era drive for encyclopedic documentation and systematic archival management. His editorial style focused on the preservation of foundational texts that outlined the constitutional and political structures of the Holy Roman Empire. The volume is recognized by historians for its scholarly ambition, as Lünig sought to standardize the erratic record-keeping of the period, though the sheer scale of his output has often been noted as a reflection of the administrative complexities inherent in the political landscape of the 1700s.
