The Codex Germaniae Diplomaticus, published in the early 18th century by the legal scholar and historian Johann Christian Lünig, serves as a monumental compilation of diplomatic documents and state papers. It was conceived as a comprehensive reference work for scholars of the Holy Roman Empire, intended to illuminate the complex legal, political, and territorial histories of the various lands under Habsburg rule, including Austria, Bohemia, and the Low Countries. Lünig, known for his extensive archival research, compiled these texts to provide primary source access to administrative records that had previously remained scattered or unpublished.

The design of the work reflects the scholarly standards of the Baroque era, prioritizing utility and archival integrity for an audience of jurists and historians. By gathering these documents into a unified series, Lünig provided a systematic framework for understanding the constitutional evolution of the German imperial territories. The volumes were well-received by contemporaries as a vital instrument for legal scholarship, ensuring that the minutiae of imperial policy and hereditary land rights were preserved for institutional study and later historiographical analysis.
