Elder House of Welf - Burgundian Group

The older of the two groups was the Burgundian group. Its oldest known member was Welf, the first Count of Altdorf. He was mentioned in 819 as father of Empress Judith. The younger sons of the first count of Altdorf, Conrad and Rudolf accompanied their sister to the court of her husband, Louis the Pious, where their ambitious spirit maintained their hereditary rank, and where they shared the happy, as well as the adverse fortunes of that sister. When Judith was surprised and confined by her stepsons, her brothers were shaven as monks but claimed and obtained permission to stand beside the throne.

Conrad had two sons: Conrad II, who succeeded him; and Hugh, from his church preferment, styled the Abbot. He is traditionally given a third son, Welf I of the Swabian group.

Conrad II succeeded his father in the dignity of Count of Paris, and recovered the estates of his grand-uncle Otkarius, in the province of Burgundy. He left an only son Rudolph, who assumed the royal crown, at the abbacy of St Maurice en Valais, in 888, and whose independence being confirmed by two victories over Arnulf, the emperor, was at last acknowledged, in a general diet of the German empire. His son, Rudolph II succeeded to this new-formed state, which included the French or western part of Switzerland, Franche-Comté, Savoy, Dauphiné, Provence, and the country between the Rhine and the Alps, and was known as the kingdom of Burgundy. He twice attempted the conquest of Italy, and for a period of three years, governed in that kingdom.

His son and successor, Conrad III, reigned upwards of fifty-six years, from 937 to 993, and enjoyed the friendship and support of the Saxon emperors. Otto I married his sister Adelaide, and she was the mother of Otto II, and the grandmother of Otto III. Conrad was succeeded by his son Rudolph III, surnamed the Lossy, who dying in 1032 without issue, the sovereignty of the kingdom of Burgundy devolved as a fief or legacy to his nephew Conrad of Swabia, who was elected emperor in 1024. With Rudolph, this branch became extinct in the male fine.

The last member of the Burgundian group was King Rudolph III of Burgundy, who died childless in 1032.
