[Sidenote: Ireland and the Pale]
What had really decided him was the opportunity offered by Richard’s absence from the realm. From the opening of his reign the king’s attention had been constantly drawn to his dependent lordship of Ireland. More than two hundred years had passed away since the troubles which followed the murder of Archbishop Thomas forced Henry the Second to leave his work of conquest unfinished, and the opportunity for a complete reduction of the island which had been lost then had never returned.

A conquest such as that in which the Normans made England their own would have spread at any rate the law, the order, the civilization of the conquering country over the length and breadth of the conquered. Unhappily Ireland, while powerless to effect its entire deliverance,
