Duke of Lauenburg

The title of Duke of Lauenburg derives from the Duchy of Saxe-Lauenburg, which, since its foundation in 1269, was ruled in succession by 29 dukes from six dynastic houses and lines, and by an additional four dukes from a temporary dynastic branch line (Anna Maria Franziska of Saxe-Lauenburg, the first would-be duchess regnant, was kept from inheriting the duchy by male rulers of neighbouring states).
