Welf

The coat-of-arms of the Duchy of Brunswick-Lüneburg

The **House of Welf** (German: *Haus von Welf*), also **Guelf** or **Guelph**, is a German dynasty that currently rules the Duchy of Brunswick-Lüneburg and is one of the current major powers in the Holy Roman Empire.

## Origins

According to a family tradition, the ancestry of the Welfs can be traced back to the Skirian prince Edeko (d. 469), a confidant of King Attila the Hun, and to his son Odoacer, King of Italy from 476. Nevertheless, an early ancestor may have been the Frankish nobleman Ruthard (d. before 790), a count in the Argengau and administrator of the Carolingian king Pepin the Younger in Alamannia. The Elder House of Welf would rule Burgundy and Swabia, but both died off. The House of Welf is the older branch of the House of Este, a dynasty whose earliest known members lived in Lombardy in the late 9th/early 10th century, sometimes called **Welf-Este**. The first member was Welf I, Duke of Bavaria; 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, Margrave of Milan. In 1070, Welf IV became duke of Bavaria.

Welf II, Duke of Bavaria 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 (*Guelfi*).

## Bavaria and Saxony

Henry IX, 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 Lothair II, Holy Roman Emperor and became also duke of Saxony on Lothair's death. Lothair left his territory around Brunswick, inherited from his mother of the Brunonids, 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), Margrave of Tuscany, later left his Swabian territories around Ravensburg, the original possessions of the Elder House of Welf, to his nephew Emperor Frederick I and thus to the House of Hohenstaufen.

The next duke of the Welf dynasty Henry the Lion recovered his father's two duchies, Saxony in 1142, Bavaria in 1156 and thus ruled vast parts of Germany. In 1168 he married Matilda (1156–1189), the daughter of Henry II of England and Eleanor of Aquitaine, and sister of Richard I of England, gaining ever more influence. His first cousin, Frederick I, Holy Roman Emperor of the Hohenstaufen dynasty, tried to get along with him, but when Henry refused to assist him once more in an Italian war campaign, conflict became inevitable. Dispossessed of his duchies after the Battle of Legnano in 1176 by Emperor Frederick I and the other princes of the German Empire eager to claim parts of his vast territories, he was exiled to the court of his father-in-law Henry II in Normandy in 1180, but returned to Germany three years later. Henry made his peace with the Hohenstaufen Emperor in 1185, and returned to his much diminished lands around Brunswick without recovering his two duchies. Bavaria had been given to Otto I, Duke of Bavaria, and the Duchy of Saxony was divided between the Archbishop of Cologne, the House of Ascania and others. Henry died at Brunswick in 1195.
