the conradines achieved the peak of their power when conrad the younger, the count of oberlahngau and the duke of franconia, was chosen king of east francia in 911. at least four stays by conrad in weilburg are attested to. the conradines were not, however, able to establish a royal dynasty. according to widukind of corvey, conrad on his deathbed in weilburg recommended to his brother, margrave (and later duke) eberhard iii of franconia, to forgo any ambition for the german crown and offer it instead to henry of saxony, one of his principal opponents, since he considered henry to be the only prince capable of holding the kingdom together in the face of internal rivalries among the dukes. this event would become known as the "weilburg testament," but is now considered by some historians to be a legend circulated by one of the liudolfings.
