Welf VI

  Notater:

Welf VI (1115 - 15 December 1191) was the margrave of Tuscany (1152-1162) and duke of Spoleto (1152-1162), the third son of Henry IX, Duke of Bavaria, and a member of the illustrious family of the Welf.

Welf inherited the familial possessions in Swabia, including the counties of Altdorf and Ravensburg, while his eldest brother Henry the Proud received the duchies of Bavaria and Saxony and his elder brother Conrad entered the church. Henry married Welf to Uta, the daughter of Godfrey of Calw, count palatine of the Rhine. On Godfrey's death in 1131, a dispute opened up between Godfrey's nephew Adalbert and Welf over the inheritance of Calw.
