King Conor died (A.D. 833), and was succeeded by Nial III., surnamed Nial of Callan. The military events of this last reign are so intimately bound up with the more brilliant career of the next ruler—Melaghlin, or Malachy I.—that we must reserve them for the introduction to the next chapter. CHAPTER II. KINGS OF THE NINTH CENTURY (CONTINUED)—NIAL III.—MALACHY I.—HUGH VII. When, in the year 833, Nial III. received the usual homage and hostages, which ratified his title of _Ard-Righ_, the northern invasion had clearly become the greatest danger that ever yet had threatened the institutions of Erin. Attacks at first predatory and provincial had so encouraged the Gentile leaders of the second generation that they began to concert measures and combine plans for conquest and colonization. To the Vikings of Norway the fertile Island with which they were now so familiar, whose woods were bent with the autumnal load of acorns, mast, and nuts, and filled with numerous herds of swine—their favourite food—whose pleasant meadows were well stored with beeves and oxen, whose winter was often as mild as their northern summer, and whose waters were as fruitful in fish as their own Lofoden friths; to these men, this was a prize worth fighting for; and for it they fought long and desperately. King Nial inherited a disputed sovereignty from his predecessor, and the Southern annalists say he did homage to Felim of Munster, while those of the North—and with them the majority of historians—reject this statement as exaggerated and untrue. He certainly experienced continual difficulty in maintaining his supremacy, not only from the Prince of Cashel, but from lords of lesser grade—like those of Ossory and Ulidia; so that we may say, while he had the title of King of Ireland, he was, in fact, King of no more than Leath-Con, or the Northern half. The central Province, Meath, long deserted by the monarchs, had run wild into independence, and was parcelled out between two or three chiefs, descendants of the same common ancestor as the kings, but distinguished from them by the tribe-name of "the _Southern_ Hy-Nial." Of these heads of new houses, by far the ablest and most famous was Melaghlin, who dwelt near Mullingar, and lorded it over western Meath; a name with which we shall become better acquainted presently. It does not clearly appear that Melaghlin was one of those who actively resisted the prerogatives of this monarch, though others of the Southern Hy-Nial did at first reject his authority, and were severely punished for their insubordination, the year after his assumption of power.
