In 1115 Alexander introduced a colony of Canons Regular to Scone, from Nastley Abbey, in Yorkshire, and some years later he brought canons to the Diocese of Dunkeld, and in 1122 he founded a Priory of Canons Regular on an island at the east end of Loch Tay.[52] Alexander was succeeded by his brother, David I., who carried out vigorously the same ecclesiastical policy. While still Prince of Cumbria, he, about 1115, appointed an inquisition of the elders and wise men of Cumbria to inquire into the lands and churches which formerly belonged to the See of Glasgow. The Prince appointed his tutor John to the revived bishopric, and in 1147 a dean and chapter, after the model of Sarum, were introduced. On his accession to the throne David proceeded diligently with the establishment of bishoprics and monasteries. It is said of him by Ailred of Rivaux[53] that, “Whereas he had found in the whole kingdom of Scotland three or four bishoprics only, what with ancient ones which he restored and new ones which he founded, he left nine at his death.” The bishoprics which existed at his accession were those of St. Andrews, Moray, and Dunkeld. Those he founded were the Dioceses of Rosemarkie, Ross, Aberdeen, and Caithness. Glasgow, as we have seen, he re-established, and the See of Galloway was also restored. Under King David I. a final effort was made to suppress the Culdees, or rather to absorb them into the general system as approved by Rome. Those of St. Andrews were with difficulty dispossessed. The Culdees of Lochleven were suppressed. Those of Monymusk, in Aberdeenshire, were brought under the control of the Bishop of St. Andrews. Not only were the old establishments suppressed, but new monastic orders were everywhere introduced, Dunfermline Abbey was remodelled and Benedictines brought to it from Canterbury. The same order was introduced at Urquhart in Inverness-shire. After Moray had been brought into subjection, the Monastery of Kinloss was founded and peopled with Cistercians from Melrose. Of other monastic institutions throughout the country many others were re-established on a new footing and received the benefactions of the king. In 1113 he had (as Earl) founded a monastery at Selkirk for Benedictine Monks of the Order of Tyron. This was afterwards removed to Kelso, while the establishments of Melrose, Dundrennan, Newbattle, Coldingham, Holyrood, Cambuskenneth were fostered and strengthened. The efforts of King David in the first half of the twelfth century carried out vigorously in Scotland the system inaugurated by St. Margaret, which was, indeed, the distinguishing feature of the period throughout Europe. He, no doubt, had policy as well as religion in view, and believed that in importing numerous bands of educated monks into the border lands of his kingdom, both in the North and South, he was doing the best possible to spread the benefits of education and civilisation in those unsettled localities, and was thus consolidating his dominion.
