From these ceremonies at York Henry returned to London, and there, before Michaelmas, envoys came to him to announce and to put into legal form another significant addition to his empire, significant certainly of its imposing power though the reasons which led to this particular step are not known to us. These envoys were from Roderick, king of Connaught, who, when Henry was in Ireland, had refused all acknowledgment of him, and they now came to make known his submission. In a great council held at Windsor the new arrangement was put into formal shape. In the document there drawn up Roderick was made to acknowledge himself the liege-man of Henry and to agree to pay a tribute of hides from all Ireland except that part which was directly subject to the English invaders. On his side Henry agreed to recognize Roderick as king under himself as long as he should remain faithful, and also the holdings of all other men who remained in his fealty. Roderick should rule all Ireland outside the English settlement, at least for the purposes of the tribute, and should have the right to claim help from the English in enforcing his authority if it should seem necessary. Such an arrangement would have in all probability only so much force as Roderick might be willing to allow it at any given time, and yet the mere making of it is a sign of considerable progress in Ireland and the promise of more. At the same council Henry appointed a bishop of Waterford, who was sent over with the envoys on their return to be consecrated. At York the king had gone on with his forest prosecutions, and there as before against clergy as well as laity. Apparently the martyrdom of Archbishop Thomas had secured for the Church nothing in the matter of these offences. The bishops did not interfere to protect the clergy, says one chronicler; and very likely in these cases the Church acknowledged the power rather than the right of the king. At the end of October a papal legate, Cardinal Hugo, arrived in England, but his mission accomplished nothing of importance that we know of, unless it be his agreement that Henry should have the right to try the clergy in his own courts for violations of the forest law. This agreement at any rate excited the especial anger of the monastic chroniclers who wrote him down a limb of Satan, a robber instead of a shepherd, who seeing the wolf coming abandoned his sheep. In a letter to the pope which the legate took with him on his return to Rome, Henry agreed not to bring the clergy in person before his courts except for forest offences and in cases concerning the lay services due from their fiefs. On January 25, 1176, a great council met at Northampton, and there Henry took up again the judicial and administrative reforms which had been interrupted by the conflict with Becket and by the war with his sons.
