Read the full account
From 1685 Leibniz was charged to write the history and genealogy of the House of Guelph, travelling to archives in Germany and Italy. It served Hanover’s electoral and later British succession claims; those politics are named, not erased.
Context
GWLB and Britannica independently print the historian’s brief. The work remained unfinished at his death. This is not the 1684 calculus paper and not a later British statute he signed.
Gottfried Wilhelm Leibniz’s documented role is bounded by other offices and collaborators named in the sources below.
Conventional years are 1646–1716. Surviving public files are GWLB Nachlass pages, the Akademie-Ausgabe, SEP, and encyclopedias. Leibniz did not typeset those later pages. Later electronic computers are not this life.
Why it matters
Knowledge-access path via court historiography. High confidence on the commission; medium on unique succession coefficients.
Who was responsible
Contribution type and responsibility level for each recorded actor — not sole-author shorthand.
Direct responsibility

Court historian on a dynastic brief. Archivists and unnamed copyists share Italian and German journeys.
