Adolphus XI of Schauenburg[1] (Low German: Alef or Alv, German: Adolf von Schauenburg, Danish: Adolf 8. af Holsten-Rendsborg) (1401 – 4 December 1459), as Adolph I Duke of Schleswig (Danish: Sønderjylland, formerly Slesvig), and as Adolph VIII Count of Holstein-Rendsburg, was the mightiest vassal of the Danish realm.[2]
- ^ The numbering varies between authors: some authors call him Adolphus XI of Schauenburg, because there were ten earlier Adolphs among his siblings in the House of Schauenburg, others call him Adolph VIII, Count of Holstein-Rendsburg, because he was the eighth count of that name ruling there. As duke of Schleswig he was Adolph I.
