and after several unsuccessful attempts a compromise was effected in 819 when the parties agreed to share the realm. In 820 Herioldus was baptized at Mainz and received from the emperor a grant of Riustringen in N.E. Friesland. In 827 he was expelled from his kingdom, but St Anskar, who had been sent with Herioldus to preach Christianity, remained at his post. In 836 we find one Horic as king of the Danes; he was probably a son of Godefridus. During his reign there was trouble with the emperor as to the overlordship of Frisia. In the meantime Herioldus remained on friendly terms with Lothair and received a further grant of Walcheren and the neighbouring districts. In 850 Horic was attacked by his own nephews and compelled to share the kingdom with them, while in 852 Herioldus was charged with treachery and slain by the Franks. In 854 a revolution took place in Denmark itself. Horic’s nephew Godwin, returning from exile with a large following of Northmen, overthrew his uncle in a three days’ battle in which all members of the royal house except one boy are said to have perished. This boy now became king as “Horicus junior.” Of his reign we know practically nothing. The next kings mentioned are Sigafrid and Halfdane, who were sons of the great Viking leader Ragnarr Loðbrok. There is also mention of a third king named Godefridus. The exact chronology and relationship of these kings it is impossible to determine, but we know that Healfdene died in Scotland in 877, while Godefridus was treacherously slain by Henry of Saxony in 885. During these and the next few years there is mention of more than one king of the names Sigefridus and Godefridus: the most important event associated with their names is that two kings Sigefridus and Godefridus fell in the great battle on the Dyle in 891.
We now have the names of several kings, Heiligo, Olaph (of Swedish origin), and his sons Chnob and Gurth. Then come a Danish ruler Sigeric, followed by Hardegon, son of Swein, coming from Norway. At some date after 916 we find mention of one “Hardecnuth Urm” ruling among the Danes. Adam of Bremen, from whom these details come, was himself uncertain whether “so many kings or rather tyrants of the Danes ruled together or succeeded one another at short intervals.” Hardecnuth Urm is to be identified with the famous Gorm the old, who married Thyra Danmarkarbót: their son was Harold Bluetooth. (A. Mw.)
Medieval and Modern.—Danish history first becomes authentic at the beginning of the 9th century. The Danes, the southernmost branch of the Scandinavian family, referred to by Alfred (c. 890) as occupying Jutland, the islands and Scania, were, in 777, strong enough to defy the Frank empire by harbouring its fugitives. Five years later we find a Danish king, Sigfrid, among the princes who assembled at Lippe in 782 to make their submission to Charles the Great. About the same time Willibrord, from his see at Utrecht, made an unsuccessful attempt to convert the “wild Danes.” These three salient facts are practically the sum of our knowledge of early Danish history previous to the Viking period. That mysterious upheaval, most generally attributed to a love of adventure, stimulated by the pressure of over-population, began with the ravaging of Lindisfarne in 793, and virtually terminated with the establishment of Rollo in Normandy (911). There can be little doubt that the earlier of these expeditions were from Denmark, though the term Northmen was originally applied indiscriminately to all these terrible visitants from the unknown north. The rovers who first chastened and finally colonized southern England and Normandy were certainly Danes.
The Viking raids were one of the determining causes of the establishment of the feudal monarchies of western Europe, but the untameable freebooters were themselves finally subdued by the Church. At first sight it seems curious that Christianity should have been so slow to reach Conversion of
the Danes.Denmark. But we must bear in mind that one very important consequence of the Viking raids was to annihilate the geographical remoteness which had hitherto separated Denmark from the Christian world. Previously to 793 there lay between Jutland and England a sea which no keel had traversed within the memory of man. The few and peaceful traders who explored those northern waters were careful never to lose sight of the Saxon, Frisian and Frankish shores during their passage. Nor was communication with the west by land any easier. For generations the obstinately heathen Saxons had lain, a compact and impenetrable mass, between Scandinavia and the Frank empire, nor were the measures adopted by Charles the Great for the conversion of the Saxons to the true faith very much to the liking of their warlike Danish neighbours on the other side. But by the time that Charles had succeeded in “converting” the Saxons, the Viking raids were already at their height, and though generally triumphant, necessity occasionally taught the Northmen the value of concessions. Thus it was the desire to secure his Jutish kingdom which induced Harold Klak, in 826, to sail up the Rhine to Ingelheim, and there accept baptism, with his wife, his son Godfred and 400 of his suite, acknowledging the emperor as his overlord, and taking back with him to Denmark the missionary monk Ansgar. Ansgar preached in Denmark from 826 to 861, but it was not till after the subsidence of the Viking raids that Adaldag, archbishop of Hamburg, could open a new and successful mission, which resulted in the erection of the bishoprics of Schleswig, Ribe and Aarhus (c. 948), though the real conversion of Denmark must be dated from the baptism of King Harold Bluetooth (960).
Meanwhile the Danish monarchy was attempting to aggrandize itself at the expense of the Germans, the Wends who then occupied the Baltic littoral as far as the Vistula, and the other Scandinavian kingdoms. Harold Bluetooth (940-986) subdued German territory south of the Danish expansion.Eider, extended the Danevirke, Denmark’s great line of defensive fortifications, to the south of Schleswig and planted the military colony of Julin or Jomsborg, at the mouth of the Oder. Part of Norway was first seized after the united Danes and Swedes had defeated and slain King Olaf Trygvessön at the battle of Svolde (1000); and between 1028 and 1035 Canute the Great added the whole kingdom to his own; but the union did not long survive him. Equally short-lived was the Danish dominion in England, which originated in a great Viking expedition of King Sweyn I.
The period between the death of Canute the Great and the accession of Valdemar I. was a troublous time for Denmark. The kingdom was harassed almost incessantly, and more than once partitioned, by pretenders to the throne, who did not scruple to invoke the interference of the Consolidation of

Yet, throughout this chaos, one thing made for future stability, and that was the growth and consolidation of a national church, which culminated in the erection of the archbishopric of Lund (c. 1104) and the consequent ecclesiastical independence of Denmark. The third archbishop of Lund was Absalon (1128–1201), Denmark’s first great statesman, who so materially assisted Valdemar I. (1157–1182) and Canute VI. (1182–1202) to establish the dominion of Denmark over the Baltic, mainly at the expense of the Wends. The policy of Absalon was continued on a still vaster scale by Valdemar II. (1202–1241), at a time when the German kingdom was too weak and distracted to intervene to save its seaboard; but the treachery of a vassal and the loss of one great battle sufficed to plunge this unwieldy, unsubstantial empire in the dust. (See Valdemar I., II., and Absalon.)
Yet the age of the Valdemars was one of the most glorious in Danish history, and it is of political importance as marking a turning-point. Favourable circumstances had, from the first, given the Danes the lead in Scandinavia. They held the richest and therefore the most populous lands, and geographically they were nearer than their neighbours to western civilization. Under the Valdemars, however, the ancient patriarchal system was merging into a more complicated development, of separate estates. The monarchy, now dominant, and far wealthier than before, rested upon the support of the great nobles, many of whom held their lands by feudal tenure, and constituted the royal Raad, or council. The clergy, fortified by royal privileges,
