Codex Germaniae diplomaticus, Worinnen Viele vortreffliche, und zum Theil noch niemahls zum Vorschein gekommene, auch zur Illustration der Teutschen Reichs-Historie und Juris Publicik, höchstnöthige Documenta enthalten sind,... ans Licht gegeben Von Johann Christian Lünig

The Codex Germaniae diplomaticus was compiled and published by Johann Christian Lünig during the early 18th century, a period marked by a growing intellectual interest in the constitutional history and legal frameworks of the Holy Roman Empire. As a prolific scholar and jurist, Lünig aimed to aggregate disparate and often inaccessible archival documents to provide a comprehensive primary source for researchers of German imperial history and public law.

The work stands as a monumental exercise in archival preservation, functioning as a scholarly bridge between medieval diplomatic traditions and modern legal interpretation. Lünig's methodology focused on transparency and accessibility, gathering records that had previously remained obscure or unpublished. The collection was well-received among contemporary jurists and historians as a vital repository of the Reichs-Historie, cementing Lünig's reputation as a key figure in the systematic documentation of early modern European statecraft.
