There was a second uprising of the Athach-Tuatha later on,[13] when they massacred their masters on Moy Bolg. The lawful heir to the throne was yet unborn at the time of this massacre and so escaped. This was the celebrated Tuathal [Too-a-hal, now Toole], who ultimately succeeded to the throne and became one of the most famous of all the pre-Patrician kings. It was he who first established or cut out the province of Meath. The name Meath had always existed as the appellation of a small district near which the provinces of Ulster, Connacht, Leinster, and the two Munsters joined. Tuathal cut off from each of the four provinces the angles adjoining it, and out of these he constituted a new province[14] to be thenceforth the special estate, demesne, and inheritance of the High-kings of Ireland. He built, or rebuilt, four palaces in the four quarters of the district he had thus annexed, all of them celebrated in after times--of which more later on. It was he also who, under evil auspices and in an evil hour, extorted from Leinster the first Borumha,[15] or Boru tribute,--_nomen infaustum_--a step which contributed so powerfully to mould upon lines of division and misery the history of our unhappy country from that day until the present, by estranging the province of Leinster, throwing it into the arms of foreigners, and causing it to put itself into opposition to the rest of Ireland. This unhappy tribute, of which we shall hear more later on, was imposed during the reigns of forty kings. Thirteen years after the death of Tuathal, Cáthaoir [Cauheer], celebrated for his Will or Testament,[16] reigned; he was of pure Leinster blood, and the men of that province have always felicitated themselves upon having given at least this one great king to Ireland. It is from him that the great Leinster families--the O'Tooles, O'Byrnes, Mac Morroughs or Murphys, O'Conor Falys, O'Gormans, and others--descend. He was slain, A.D. 123, by Conn of the Hundred Battles.[17] There are few kings during the three hundred years preceding and following the birth of Christ more famous than this Conn, and there is a very large body of saga collected round him and his rival Eoghan [Owen], the king of Munster who succeeded in wresting half the sovereignty from him. As the result of their conflicts that part of Ireland which lies north of the Escir Riada,[18] or, roughly speaking, that lies north of a line drawn from Dublin to Galway, has from that day to this been known as Conn's Half, and that south of the same line as Owen's Half. Owen was at last slain by him of the hundred battles at the fight of Moy Léana.
