While these deplorable sacrileges, too rapidly executed perhaps to be often either prevented or punished, were taking place, Conor the King had on his hand a war of succession, waged by the ablest of his contemporaries, Felim, King of Munster, who continued during this and the subsequent reign to maintain a species of rival monarchy in Munster. It seems clear enough that the abandonment of Tara, as the seat of authority, greatly aggravated the internal weakness of the Milesian constitution. While over-centralization is to be dreaded as the worst tendency of imperial power, it is certain that the want of a sufficient centralization has proved as fatal, on the other hand, to the independence of many nations. And anarchical usages once admitted, we see from the experience of the German Empire, and the Italian republics, how almost impossible it is to apply a remedy. In the case before us, when the Irish Kings abandoned the old mensal domain and betook themselves to their own patrimony, it was inevitable that their influence and authority over the southern tribes should diminish and disappear. Aileach, in the far North, could never be to them what Tara had been. The charm of conservatism, the halo of ancient glory, could not be transferred. Whenever, therefore, ambitious and able Princes arose in the South, they found the border tribes rife for backing their pretensions against the Northern dynasty. The Bards, too, plied their craft, reviving the memory of former times, when Heber the Fair divided Erin equally with Heremon, and when Eugene More divided it a second time with Con of the Hundred Battles. Felim, the son of Crimthan, the contemporary of Conor II. and Nial III., during the whole term of their rule, was the resolute assertor of these pretensions, and the Bards of his own Province do not hesitate to confer on him the high title of _Ard-Righ_. As a punishment for adhering to the Hy-Nial dynasty, or for some other offence, this Christian king, in rivalry with "the Gentiles," plundered Kildare, Burrow, and Clonmacnoise—the latter perhaps for siding with Connaught in the dispute as to whether the present county of Clare belonged to Connaught or Munster. Twice he met in conference with the monarch at Birr and at Cloncurry—at another time he swept the plain of Meath, and held temporary court in the royal rath of Tara. With all his vices lie united an extraordinary energy, and during his time, no Danish settlement was established on the Southern rivers. Shortly before his decease (A.D. 846) he resigned his crown and retired from the world, devoting the short remainder of his days to penance and mortification. What we know of his ambition and ability makes us regret that he ever appeared upon the scene, or that he had not been born of that dominant family, who alone were accustomed to give kings to the whole country.
