Conrad, born in Bamberg, had been appointed…

One year later he had acted as regent for Germany, together with his elder brother, Frederick II of Swabia.

At the death of Henry (1125), Conrad had unsuccessfully supported Frederick for the kingship of Germany.

Frederick was placed under a ban and Conrad was deprived of Franconia and the Kingdom of Burgundy, of which he was rector.

With the support of the imperial cities, Swabia, and the Duchy of Austria, Conrad is elected antiking to the Holy Roman Emperor, Lothair II, at Nuremberg in December 1127, thus establishing the Hohenstaufen dynasty.
