Yet the general rule that the monarch was to belong to the race of Miledh was adhered to almost without exception. One hundred and eighteen sovereigns, according to the moat accredited annals, governed the whole island from the Milesian conquest to St. Patrick in 432. Of these, sixty were of the family of Heremon, settled in the northern part of the island; twenty-nine of the posterity of Heber, settled in the south; twenty-four of that of Ir; three issued from Lugaid, the son of Ith. All these were of the race of Miledh; one only was a firbolg, or plebeian, and one a woman.

It is certainly very remarkable that for so long a time—nearly two thousand years, according to the best chronologists—Ireland was ruled by princes of the same family. The fact is unparalleled in history, and shows that the people were firmly attached to their constitution, such as it was. It extorted the admiration of Sir John Davies, the attorney-general of James I, and later of Lord Coke.

The functions of the provincial kings of Ulster, Munster, Leinster, and Connaught, were in their several districts the same as those which the Ard-Righ exercised over the whole country. They also had their feuds and alliances with the inferior chieftains, and in peaceful times there was also a reciprocity of obligations between them. Presents were given by the superiors, tributes by the inferiors; deliberations in assembly, mutual agreement for public defence, wars against a common enemy, produced among them traditional rules which were generally followed, or occasional dissensions.

Sometimes a province had two kings, chiefly Munster, which was often divided into north and south. Each king had his heir-apparent, the same as the monarch. Indeed, every hereditary office had, besides its actual holder, its Tanist, with right of succession. Hence causes of division and feuds were needlessly multiplied; yet all the Celtic tribes adhered tenaciously to all those institutions which appeared rooted in their very nature, and which contributed to foster the traditional spirit among them.

For these various offices and their inherent rights were all derived from the universally prevailing family or clannish disposition. Genealogies and traditions ruled the whole, and gave, as we have seen, to their learned men a most important part and function in the social state; and thus what the Greek and Latin authors, Julius Caesar principally, have told us of the Celtic Druids, is literally true of the ollamhs in their various degrees.

But the clannish spirit chiefly showed itself in the authority and rights of every chieftain in his own territory. He was truly the patriarch of all under him, acknowledged as he was to be the head of the family, elected by all to that office at the death of his predecessor, after due consultation with the files and shanachies, to whom were intrusted the guardianship of the laws which governed the clan, and the preservation of the rights of all according to the strict order of their genealogies and the traditional rules to be observed.

The power of the chieftain was immense, although limited on every side by laws and customs. It was based on the deep affection of relationship which is so ardent in the Celtic nature. For all the clansmen were related by blood to the head of the tribe, and each one took a personal pride in the success of his undertakings. No feudal lord could ever expect from his vassals the like self-devotion; for, in feudalism, the sense of honor, in clanship, family affection, was the chief moving power.

In clanship the type was not an army, as in feudalism, but a family. Such a system, doubtless, gave rise to many inconveniences. "The breaking up of all general authority," says the Very Rev. Dean Butler (Introduction to Clyn's "Annals"), "and the multiplication of petty independent principalities, was an abuse incident on feudalism; it was inherent in the very essence of the patriarchal or family system. It began, as feudalism ended, with small independent societies, each with its own separate centre of attraction, each clustering round the lord or the chief, and each rather repelling than attracting all similar societies. Yet it was not without its advantages. If feudalism gave more strength to attack an enemy, clanship secured more happiness at home. The first implied only equality for the few, serfdom or even slavery for the many; the other gave a feeling of equality to all."

It was, no doubt, this feeling of equality, joined to that of relationship, which not only secured more happiness for the Celt, but which so closely bound the nobility of the land to the inferior classes, and gave these latter so ardent an affection for their chieftains. Clanship, therefore, imparted a peculiar character to the whole race, and its effect was so lasting and seemingly ineradicable as to be seen in the nation to-day.

Wherever feudalism previously prevailed, we remark at this time a fearful hatred existing between the two classes of the same nation; and the great majority of modern revolutions had their origin in that terrible antagonism. The same never existed, and could not exist, in Celtic Countries; and if England, after a conflict of many centuries, had not finally succeeded in destroying or exiling the entire nobility of Ireland, we should, doubtless, see to this very day that tender attachment between high and low, rich and poor, which existed in the island in former ages.
