Fitz-Adelm's son, Richard de Burgo, generally called MacWilliam by the Irish, married Una, Cathal Crovdearg's grand-daughter, and procured from Henry III. a grant of all Connaught, except five cantreds reserved for the support of the post at Athlone. From the first the position of the Anglo-Normans in Connaught differed from their position in other parts of Ireland. They were there rather as allies of the native chiefs than as conquerors, and the easy lapse of their descendants into Irish habits is the less to be wondered at. Richard de Burgo obtained a confirmation of his grant in 1226, through the favour of his kinsman, the great justiciar, Hubert, and he soon afterwards made himself master of Galway, which he fortified strongly, and made the chief place of Connaught. After his time the O'Connors never regained possession of it, and the importance of the royal tribe steadily diminished during the whole of the thirteenth century. Richard de Burgo's eldest son Walter married Maud, daughter and heiress of the younger Hugo de Lacy, who died in 1243, and he thus became Earl of Ulster as well as Lord of Connaught. His son Richard, commonly called the Red Earl, advanced the power of the Anglo-Norman state to the furthest point which it ever attained. [Sidenote: Poverty of the colony under Henry III.] Constant war is not favourable to the production of wealth, and it seems probable that no very considerable progress was made in the arts of peace. Tallage was first imposed on Ireland in 1217, in the name of Henry III., but it seems to have yielded little, and a generation later there was equal difficulty in collecting a tithe for the Pope. Innocent IV. ordered that a sum should be so raised for the liberation of the Holy Land, and very stringent letters were sent to Ireland in 1254; but collector Lawrence Sumercote declared that the difficulties were insuperable. The Irish, he explained, never saved anything, but lived riotously and gave liberally to all, and he professed that he would 'rather be imprisoned than crucified any longer in Ireland for the business of the Cross.' The plan of drawing upon Ireland for English or Continental wars was, however, largely practised during the reign of Henry III., and it tended to sap the strength of the colony. Ready money might be scarce, but there were men, and they could be ill-spared from the work of defending their lands against a native race who were ever on the watch to take advantage of their absence or neglect.
