Note {49} — I. THE GERMANS AND THE EMPIRE TO 1073

Haroun-al-Raschid was Caliph of the Mohammedan world from 786–809, with his capital at Bagdad. His caliphate is the golden age of the Mohammedans reflected in the "Arabian Nights." The connection of Karl with Haroun and especially the negotiations mentioned here in regard to Jerusalem gave rise to the later legends concerning the crusades of Karl.
