near Fontenay (Fontanetum) by Louis the German and Charles the Bald. The empire now fell apart, not from the force of national hatreds, but in consequence of the partition now made and known as the Treaty of Verdun (August, 843), which divided the territory between the sons of Louis the Pious: Lothair, Louis the German (843-76), and Charles the Bald, and which finally resulted in the complete overthrow of the Carlovingian monarchy.
As the imperial power grew weaker, the Church gradually raised itself above the State. The scandalous behaviour of Lothair II, who, divorced himself from his lawful wife in order to marry his concubine, brought deep disgrace on his kingdom. The Church however, now an imposing and well-organized power, sat in judgment on the adulterous king. When Lothair II died, his uncles divided his possessions between them; by the Treaty of Ribemont (Mersen), Lorraine, which lay between the East Frankish Kingdom of Louis the German and the West Frankish Kingdom of Charles the Bald, was assigned to the East Frankish Kingdom. In this way a long-enduring boundary was definitely drawn between the growing powers of Germany and France. By a curious chance this boundary coincided almost exactly with the linguistic dividing line. Charles the Fat (876-87), the last son of Louis the German, united once more the entire empire. But according to old Germanic ideas the weak emperor forfeited his sovereignty by his cowardice when the dreaded Northmen appeared before Paris on one of their frequent incursions into France, and by his incapacity as a ruler. Consequently the Eastern Franks made his nephew Arnulf (887-99) king. This change was brought about by a revolt of the laity against the bishops in alliance with the emperor. The danger of Norman invasion Arnulf ended once and for all by his victory in 891 at Louvain on the Dyle. In the East also he was victorious after the death (894) of Swatopluk, the great King of Moravia. The conduct of some of the great nobles forced him to turn for aid to the bishops; supported by the Church, he was crowned emperor at Rome in 896. Theoretically his rule extended over the West Frankish Kingdom, but the sway of his son, Louis the Child (899-911), the last descendant of the male line of the German Carlovingians, was limited entirely to the East Frankish Kingdom. Both in the East and West Frankish Kingdoms, in this era of confusion, the nobility grew steadily stronger, and freemen in increasing numbers became vassals in order to escape the burdens that the State laid on them; the illusion of the imperial title could no longer give strength to the empire. Vassal princes like Guido and Lamberto of Spoleto, and Berengar of Friuli, were permitted to wear the diadem of the Caesars.
As the idea of political unity declined, that of the unity of the Church increased in power. The Kingdom of God, which the royal priest, Charlemagne, by his overshadowing personality had, in his own opinion, made a fact, proved to be an impossibility. Church and State, which for a short time were united in Charlemagne, had, as early as the reign of Louis the Pious, become separated. The Kingdom of God was now identified with the Church. Pope Nicholas I asserted that the head of the one and indivisible Church could not be subordinate to any secular power, that only the pope could rule the Church, that it was obligatory on princes to obey the pope in spiritual things, and finally that the Carlovingians had received their right to rule from the pope. This grand idea of unity, this all-controlling sentiment of a common bond, could not be annihilated even in these troubled times when the papacy was humiliated by petty Italian rulers. The idea of her unity gave the Church the strength to raise herself rapidly to a position higher than that of the State. From the age of St. Boniface the Church in the East Frankish Kingdom had direct relations with Rome, while numerous new churches and monasteries gave her a firm hold in this region. At an early date the Church here controlled the entire religious life and, as the depositary of all culture, the entire intellectual life. She had also gained frequently decisive influence over German economic life, for she disseminated much of the skill and many of the crafts of antiquity. Moreover the Church itself had grown into an economic power in the East Frankish Kingdom. Piety led many to place themselves and their lands under the control of the Church.
There was also in this period a change in social life that was followed by important social consequences. The old militia composed of every freeman capable of bearing arms went to pieces, because the freemen constantly decreased in number. In its stead there arose a higher order in the State, which alone was called on for military service. In this chaotic era the German people made no important advance in civilization. Nevertheless the union that had been formed between Roman and German elements and Christianity prepared the way for a development of the East Frankish Kingdom in civilization from which great results might be expected. At the close of the Carlovingian period the external position of the kingdom was a very precarious one. The piratic Northmen boldly advanced far into the empire; Danes and Slavs continually crossed its borders; but the most dangerous incursions were those of the Magyars, who in 907 brought terrible suffering upon Bavaria; in their marauding expeditions they also ravaged Saxony, Thuringia, and Swabia. It was then that salvation came from the empire itself. The weak authority of the last of the Carlovingians, Louis the Child, an infant in years, fell to pieces altogether, and the old ducal form of government revived in the several tribes. This was in accordance with the desires of the people. In these critical times the dukes sought to save the country; still they saw clearly that only a union of all the duchies could successfully ward off the danger from without; the royal power was to find its entire support in the laity. Once more, it is true, the attempt was made by King Conrad I (911-18) to make the Church the basis of the royal power, but the centralizing clerical policy of the king was successfully resisted by the subordinate powers. Henry I (919-36) was the free choice of the lay powers at Fritzlar. On the day he was elected the old theory of the State as the personal estate of the sovereign was finally done away with, and the Frankish realm was transformed into a German one. The manner of his election made plain to Henry the course to be pursued. It was necessary to yield to the wish of the several tribes to have their separate existence with a measure of self-government under the imperial power recognized. Thus the duchies were strengthened at the expense of the Crown. The fame of Henry I was assured by his victory over the Magyars near Merseburg (933). By regaining Lorraine, that had been lost during the reign of Conrad, he secured a bulwark on the side towards France that permitted the uninterrupted consolidation of his realm. The same result was attained on other frontiers by his successful campaigns against the Wends and Bohemians. Henry's kingdom was made up of a confederation of tribes, for the idea of a "King of the Germans" did not yet exist. It was only as the "Holy Roman Empire of the German Nation" that Germany could develop from a union of German tribes to a compact nation. As supporters of the supreme power, as vassals of the emperor, the Germans were united.
This imperial policy was continued by Otto I, the Great (936-73). During his long reign Otto sought to found a strong central power in Germany, an effort at once opposed by the particularistic powers of Germany, who took advantage of disputes in the royal
