Prince Wilhelm Karl, Duke of Urach

Prince Wilhelm of Urach, Count of Württemberg, 2nd Duke of Urach, was a German prince who was elected in June 1918 as King of Lithuania, with the regnal name of Mindaugas II. He never assumed the crown, however, as German authorities declared the election invalid; the invitation was withdrawn in November 1918. From 17 July 1869 until his death, he was the head of the morganatic Urach branch of the House of Württemberg.
