Гуго Капет
When Laon was taken by Charles, Duke of Lower Lorraine, in 988, Adalberon was put into prison, whence he escaped and sought the protection of Hugh Capet, king of France. Winning the confidence of Charles of Lorraine and of Arnulf, archbishop of Reims, he was restored to his see; but in 991 he gave Laon, together with Charles and Arnulf, into the hands of Hugh Capet.
