The Conqueror is said to have at one time entertained the project of bringing Ireland under subjection, but notwithstanding its proximity to England, and the obvious advantages that would result from uniting the two islands under one government, neither he nor his three immediate successors made any effort to accomplish this object. In the reign of Henry the Second however, a circumstance occurred which drew the attention of the English sovereign to the state of Ireland, and led to consequences most important to both countries. In the year 1169 Dermod, king of Leinster, who had been expelled by O'Connor, king of Connaught, sought the protection of Henry, who accepted the tendered allegiance, and permitted his subjects to assist the Irish chief. [Sidenote: 1172. Subjection of Ireland by Henry II.]Earl Strigul (or Strongbow) took advantage of this permission, and in 1170 embarked for Ireland with a few armed retainers. He was followed two years afterwards by the king himself, with a considerable force. Henry was everywhere received as a conqueror, the Irish princes and chiefs submitting without opposition; and at a council assembled at Lismore, the laws of England are said to have been gratefully accepted by all, and established under the sanction of a solemn oath. The chieftains who had however, so readily submitted to become Henry’s vassals, as readily withdrew their allegiance on his quitting Ireland, which he was compelled to do at the end of little more than six months, in consequence of Becket’s murder, and the rebellion of his own sons. Thenceforward for the long period of 400 years, the country was distracted by local dissensions and jealousies, and the conflicts of contending chiefs. Treachery and murder everywhere prevailed. The sovereigns of England were too much occupied with the crusades, and their French wars, to attend to the state of Ireland; and although the English race maintained itself in that country, it is said to have become wilder and less civilized in each succeeding generation. “The first adventurers (we are told) trampled down the original Irish; they were themselves in their turn trampled down by the next adventurers; these by subsequent ones; and so on in a continual series, as if each race had forfeited all rights, or power of acquiring and retaining any rights whatsoever, more than a common robber or pirate.”
