The Ard-Righ Roderick, during the period of Henry the Second's stay in Ireland, had continued west of the Shannon. Unsupported by his suffragans, many of whom made peace with the invader, he attempted no military operation, nor had Henry time sufficient to follow him into his strongholds. It was reserved for this ill-fated, and, we cannot but think, harshly judged monarch, to outlive the first generation of the invaders of his country, and to close a reign which promised so brightly at the beginning, in the midst of a distracted, war-spent people, having preserved through all vicissitudes the title of sovereign, but little else that was of value to himself or others. Among the guests who partook of the Christmas cheer of King Henry at Dublin, we find mention of Tiernan O'Ruarc, the lord of Breffni and East-Meath. For the Methian addition to his possessions, Tiernan was indebted to his early alliance with Roderick, and the success of their joint arms. Anciently the east of Meath had been divided between the four families called "the four tribes of Tara," whose names are now anglicized O'Hart, O'Kelly, O'Connelly, and O'Regan. Whether to balance the power of the great West-Meath family of O'Melaghlin, or because these minor tribes were unable to defend themselves successfully, Roderick, like his father, had partitioned Meath, and given the seaward side a new master in the person of O'Ruarc. The investiture of Hugh de Lacy by King Henry with the seignory of the same district, led to a tragedy, the first of its kind in our annals, but destined to be the prototype of an almost indefinite series, in which the gainers were sometimes natives, but much oftener Normans.
