The reign of Rudolf III. (993-1032) was greatly harmful to the country, which was fast declining in prestige and prosperity. Better fitted for the cloister than for the throne, he lavished his wealth and estates on the clergy, with the view of enlisting their help against the encroaching feudal vassals. In the end, indeed, he was so reduced that he was compelled to live on alms from his priests. His own incapacities drove him to seek protection from the empire. Having no children, he appointed his nephew, the Emperor Henry II., heir to his kingdom, and even during his own lifetime he arranged to give up the reigns of government to Henry. The opposition of the Burgundian nobles and the emperor's death prevented this shameful arrangement from actually coming into force. The next emperor, Conrad II., prosecuted the claim against his stepson, Ernest II., as has been told above, and was crowned king at the Cluniacensian convent, founded by Bertha at Payerne, (1033). His elevation to the Burgundian throne was confirmed in the following year by a brilliant assembly of Burgundian, German, and Italian bishops and nobles, at Geneva. Shortly before his death in 1038, he had his son Henry installed in the kingdom, and the oath of fealty to him was taken by the Burgundian nobles at the Diet of Solothurn. Switzerland was thus very closely allied with the empire; Henry III. holding the reins of government as King of Burgundy and Duke of Alamannia or Swabia. This third amalgamation with the empire told more lastingly and influentially on the country than either the Roman or the Frankish rule had done; to a great extent it stamped on the people the German character and spirit.
