Heinrich the Black (* 1075 ; † December 13, 1126 in Ravensburg ), also Heinrich the Welf , was Duke of Bavaria (according to modern counts as Heinrich IX. ). He came from the Guelph family , his father was Welf IV. After his brother Welf V died without descendants, he succeeded him in the Duchy of Bavaria in 1120 .

Between 1095 and 1100 Heinrich and Wulfhild, the daughter of the last Duke of Saxony, Magnus, married from the Billunger family . The marriage had seven children:

With the death of his father-in-law Magnus Billung († 1106) he hoped to take over the Duchy of Saxony. But this power constellation met the resistance of the new King Heinrich V , who surprisingly installed Count Lothar von Süpplinburg (later King Lothar III ) as duke in Saxony in the middle of 1106 .

Henry the Black played a special role in the 1125 election . At first he seems to have promoted the candidacy of his son-in-law Friedrich II of Swabia . In the course of the discussions about the suitable candidate, however, he changed his mind and finally stood up for Duke Lothar von Sachsen, who thereby became Lothar III. was elected Roman-German king. Lothar had promised to give his daughter Gertrud Heinrich's son Heinrich (the proud) to wife. This marriage was concluded in 1127, although Gertrud was only 12 years old at the time.

After Lothar's election, Bavarian, Franconian and Swabian supporters proclaimed the Staufer Konrad to be the rival king in December 1125 . Heinrich the Black entered the Weingarten Monastery as a lay monk - perhaps in order not to have to go to war against his son-in-law. There he died in 1126.

His nickname “the black one” has only been attested since the 13th century. In the various representations of the Saxon lineage, he has been listed as Heinrich the Welf since the 16th century at the latest because of his origin from the Guelphs and to differentiate him from Heinrich the Lion .
