Hugh, Duke of Alsace

Hugo ( * before 863; † after 895 in Prüm Abbey ) was the only son of King Lothair II of Lotharingia, but from the church not recognized second marriage with Waldrada.

His father, the marriage recognition and thus Hugo efforts to gain the throne in Lotharingia, were unsuccessful. Lothar over to his son, 867 the Duchy of Alsace ( whether as an attempt to thereby provide facts and force the succession, or in the knowledge that the succession would no longer be enforced and his son must now be supplied, remains unclear) and imputed it the protection of his uncle Louis the German, but went over this Hugo's claims after the death of Lothair ( 869 ) and the Treaty of Mersen (870).

877 undertook Hugo the first attempt to fight for his legacy, but remained - despite support from the Lorraine nobility - unsuccessfully: 878 he was excommunicated by Pope John VII in Troyes, 879 drew Louis the Younger against him in the field, 880 the West Frankish king Ludwig III. and his brother Carloman and Ostfrankenkönig Charles the Fat, ultimately without success, because they could not get hold of him.

Louis the Younger tried to satisfy him by furnished him with counties and abbeys, which Hugo but not obvious enough, since he took up the fight again soon.

With the elimination of Hugo Lorraine root of the Carolingian Empire the means between Western and Eastern Frankish was off final story.
