| | Henry X, Duke of Bavaria - Wikipedia, the free encyclopedia |
 | | He was the son of Henry the Black, Duke of Bavaria, and Wulfhild, daughter of Magnus Billung, Duke of Saxony, and thus a member of the Welf family, and, what was quite important, senior heir of the Billung family. |
 | | After the marriage, Henry took part in the warfare between the king and the Hohenstaufen brothers, Frederick II, Duke of Swabia (who was Henry's brother-in-law, having been married with his sister Judith), and Conrad, Duke of Franconia, afterwards the German king Conrad III. |
 | | Henry's duchy of Bavaria was given to Leopold IV, Margrave of Austria, a half-brother of the new king Conrad. |
