“In 1115, after seven years of marriage, Amauberge was "abducted" from her bedchamber by William IX, Duke of Aquitaine. She was taken to a tower in his castle in Potiers called Maubergeonne. As a result, Amauberge or Dangereuse was nicknamed La Maubergeonne. Abductions like these were quite common among nobles during the Middle Ages. However, in this particular case she seems to have been a willing contributor to the affair.’1382
