The House of Welf is the older branch of the House of Este, a dynasty whose earliest known members lived in Lombardy in the 9th century, sometimes called Welf-Este. The first member was Welf IV; he inherited the property of the Elder House of Welf when his maternal uncle Welf III, Duke of Carinthia and Verona, the last male Welf of the Elder House, died in 1055. Welf IV was the son of Welf III's sister Kunigunde of Altdorf and her husband Albert Azzo II of Este, Margrave of Milan. In 1070, Welf IV became duke of Bavaria. Welf V married Countess Matilda of Tuscany, who died childless and left him her possessions, including Tuscany, Ferrara, Modena, Mantua, and Reggio, which played a role in the Investiture controversy. Since the Welf dynasty sided with the Pope in this controversy, partisans of the Pope came to be known in Italy as Guelphs; see Guelphs and Ghibellines.
Henry the Black, duke of Bavaria from 1120–1126, was the first of the three dukes of the Welf dynasty called Henry. His wife Wulfhild was the heiress of the house of Billung, possessing the territory around Lüneburg in Lower Saxony. Their son, Henry the Proud was the son-in-law and heir of Emperor Lothair of Supplinburg and became also duke of Saxony on Lothair's death. Lothair left his territory around Brunswick, inherited from his mother of the Brunonen family, to his daughter Gertrud. Her husband Henry the Proud became then the favoured candidate in the imperial election against Conrad III of the Hohenstaufen. But Henry lost the election, as the other princes feared his power and temperament, and was dispossessed of his duchies by Conrad III. Henry's brother Welf VI (1115-1191), Markgrave of Tuscany, later left his Swabian territories around Ravensburg, the original possessions of the Elder House of Welf, to his nephew Emperor Frederick Iand thus to the House of Hohenstaufen.

He incurred the wrath of Pope Innocent III and was excommunicated in 1215.
