Note 6 — Chapter III · The Entry of the Princes
George P. (George Putnam) Upton translation
Albert, Elector of Brandenburg, third son of Frederick I, was born November 9, 1414, and died March 11, 1486. He was the author of the ordinance providing for the separation of Brandenburg and Ansbach-Baireuth, and establishing primogeniture in each, which, according to the historians, is the first instance of the legal establishment of the custom of primogeniture. He was surnamed Achilles, and Ulysses, because of his valor and sagacity.
