a certain extent by their subjects. In the aftermath of William's capture at Alnwick in 1174, the Scots turned on their king's English-speaking and French-speaking subjects. William of Newburgh related the events: Walter Bower, writing a few centuries later albeit, wrote about the same event: Opposition to the Scottish kings in this period was indeed hard. The first instance is perhaps the revolt of Óengus of Moray, the Mormaer of Moray, the crushing of which led to the colonisation of Moray by foreign burgesses, and Franco-Flemish and Anglo-French aristocrats. Rebellions continued throughout the 12th century and into the 13th. Important resistors to the expansionary Scottish kings were Somhairle Mac Gille Brighdhe, Fergus of Galloway, Gille Brigte of Galloway and Harald Maddadsson, along with two kin-groups known today as the MacHeths and the Meic Uilleim. The latter claimed descent from king Donnchadh II, through his son William, and rebelled for no less a reason than the Scottish throne itself. The threat was so grave that, after the defeat of the MacWilliams in 1230, the Scottish crown ordered the public execution of the baby girl who happened to be the last MacWilliam. This was how the Lanercost Chronicle relates the fate of this last MacWilliam: Many of these resistors collaborated, and drew support not just in the peripheral Gaelic regions of Galloway, Moray, Ross and Argyll, but also from eastern "Scotland-proper", Ireland and Mann. By the end of the 12th century, the Scottish kings had acquired the authority and ability to draw in native Gaelic lords outside their previous zone of control to do their work, the most famous examples being Lochlann, Lord of Galloway and Fearchar Mac an t-Sagairt. Such accommodation assisted expansion to the Scandinavian-ruled lands of the west. Uilleam, the native Mormaer of Ross, was a pivotal figure in the expansion of the Scottish kingdom into the Hebrides, as was Ailéan mac Ruaidhrí, the key pro-Scottish Hebridean chief, who married his daughter to Uilleam, the Mormaer of Mar. The Scottish king was able to draw on the support of Alan, Lord of Galloway, the master of the Irish Sea region, and was able to make use of the Galwegian ruler's enormous fleet of ships. The Mormaers of Lennox forged links with the Argyll chieftains, bringing a kin-group such as the Campbells into the Scottish fold. Cumulatively, by the reign of Alexander III, the Scots were in a strong position
