in the conflict between eberhard iii of franconia, as conrad’s successor as count in the oberlahngau, and king otto i came the final division of the conradine dynasty. in the battle of andernach on october 2, 939, eberhard was defeated and killed by his cousin conrad kurzbold, count in niederlahngau, and eberhard’s branch of the conradine family lost the lordship over the oberlahngau. parts of the realm were transferred to conrad kurzbold’s branch of the family and other parts confiscated by the ottonian king. in these areas, after a checkered history, the house of the gisos of gudensberg prevailed until the 11th century. the area around weilburg was granted by the ottonian kings to the bishopric of worms after 1000.
