In 1166 Dermod, who had made himself odious by his tyranny, was expelled from Leinster by O'Connor and O'Rourke, who demolished his stronghold at Ferns, and transferred his kingship to the next-of-kin. The clergy appear to have been generally favourable to Dermod; and as Adrian's bull, even if not published, could hardly be a secret, it may have been their advice which induced him to go to Henry II. Dermod, though seventy-seven years old, was still active and enterprising, and he sought the king in Aquitaine or Guienne. Henry was too busy to think of going to Ireland himself, but he gave the suppliant a kind of letter of marque in the following terms:--'Henry, King of England, Duke of Normandy and Aquitaine, and Count of Anjou, to all his faithful English, Norman, Welsh, and Scots, and to all nations subject to his jurisdiction, greeting: When these present letters reach you you will know that we have received into the bosom of our grace and favour Dermod, prince of the Leinstermen. If anyone, therefore, within the bounds of our power wishes to help his restoration as our man and liege subject, let him know that he has our licence and favour for the purpose.'[31] [Sidenote: Dermod seeks allies in England.] Thus armed, Dermod returned to Bristol, which was much frequented by ships from Leinster, and he appears to have been supplied with money by his partisans there. His promise of gold and land at first attracted little attention, but after two or three weeks he was visited by Richard Fitz-Gilbert de Clare, Earl of Chepstow. Earl Richard, whose father had lost most of his lands, lent a favourable ear to Dermod, and undertook to bring an army to Ireland in the spring of 1169. The Irishman promised to give him his daughter Eva, his only legitimate child. According to Norman law Eva would bring the kingdom of Leinster to her husband and children. According to Celtic law the lands belonged to the tribe, and the royal dignity was elective. In this singular contract between MacMurrough and Fitz-Gilbert, we have the key to most of the problems which have made Ireland the despair of statesmen. [Sidenote: Earl Richard and his friends.]
