The empire of Charlemagne fell apart at the death of Louis the Pious and the split between the French-speaking Franks and the German-speaking Franks widened. The next emperor to arise was Otto, the son of a certain Henry the Fowler, a Saxon, who had been elected King of Germany by an assembly of German princes and prelates in 919. Otto descended upon Rome and was crowned emperor there in 962. This Saxon line came to an end early in the eleventh century and gave place to other German rulers. The feudal princes and nobles to the west who spoke various French dialects did not fall under the sway of these German emperors after the Carlovingian line, the line that is descended from Charlemagne, had come to an end, and no part of Britain ever came into the Holy Roman Empire. The Duke of Normandy, the King of France and a number of lesser feudal rulers remained outside. In 987 the Kingdom of France passed out of the possession of the Carlovingian line into the hands of Hugh Capet, whose descendants were still reigning in the eighteenth century. At the time of Hugh Capet the King of France ruled only a comparatively small territory round Paris. In 1066 England was attacked almost simultaneously by an invasion of the Norwegian Northmen under King Harold Hardrada and by the Latinized Northmen under the Duke of Normandy. Harold King of England defeated the former at the battle of Stamford Bridge, and was defeated by the latter at Hastings. England was conquered by the Normans, and so cut off from Scandinavian, Teutonic and Russian affairs, and brought into the most intimate relations and conflicts with the French. For the next four centuries the English were entangled in the conflicts of the French feudal princes and wasted upon the fields of France. XLVI THE CRUSADES AND THE AGE OF PAPAL DOMINION It is interesting to note that Charlemagne corresponded with the Caliph Haroun-al-Raschid, the Haroun-al-Raschid of the _Arabian Nights_. It is recorded that Haroun-al-Raschid sent ambassadors from Bagdad—which had now replaced Damascus as the Moslem capital—with a splendid tent, a water clock, an elephant and the keys of the Holy Sepulchre. This latter present was admirably calculated to set the Byzantine Empire and this new Holy Roman Empire by the ears as to which was the proper protector of the Christians in Jerusalem.
