Life
He was the son of the Upper Burgundian king Rudolph I and Guilla.[1] Following his ascent to the throne in 912, Rudolph II entered into a border conflict with the neighbouring dukes of Swabia and campaigned the Thurgau and Zurich estates. Duke Burchard II of Swabia finally defeated him in the 919 Battle of Winterthur; both rulers made peace and Rudolph married Burchard's daughter Bertha in 922.[2]
At the same time, Rudolph was asked by several Italian nobles led by Margrave Adalbert I of Ivrea to intervene in Italy on their behalf against Emperor Berengar.[3] Having entered Italy, he was crowned king at Pavia in the Basilica of San Michele Maggiore.[4] In 923, he defeated Berengar at the Battle of Firenzuola;[5] Berengar was murdered the following year,[6] possibly at the instigation of Rudolph. The king then ruled Upper Burgundy and Italy together, residing alternately in both kingdoms.
However, in 926 the Italian nobility turned against him and requested that Hugh of Arles, the effective ruler of Provence (or Lower Burgundy), rule them instead.[6] Rudolph's father-in-law Duke Burchard II of Swabia came for his support; however, he was attacked and killed near Novara by the henchmen of Archbishop Lambert of Milan. The king returned to Upper Burgundy to protect himself, assuring Hugh's coronation as King of Italy in the process. At the Diet of Worms, Rudolph rendered the royal symbol of the Holy Lance to the East Frankish king Henry the Fowler in exchange for the Swabian Basel estates.
The two Burgundian kingdoms unified from 933; Rudolph ruled until his death in 937 and was succeeded by his son Conrad.[3] After his death in 937, his daughter Adelaide was married to Hugh's son Lothair,[3] while Hugh married Rudolph's widow Bertha.[a] Adelaide later became the second wife of Otto the Great, crowned Holy Roman Emperor in 962, and the mother of Emperor Otto II.[8]
