Clan Sweeney, Clan Lamont, Clan MacLea, Clan MacLachlan and Clan MacNeill, can trace their ancestry back to the fifth century Niall of the Nine Hostages, High King of Ireland. However, in reality, the progenitors of clans can rarely be authenticated further back than the 11th century, and a continuity of lineage in most cases cannot be found until the 13th or 14th centuries. The emergence of clans had more to do with political turmoil than ethnicity. The Scottish Crown's conquest of Argyll and the Outer Hebrides from the Norsemen in the 13th century, which followed on from the pacification of the Mormaer of Moray and the northern rebellions of the 12th and 13th centuries, created the opportunity for war lords to impose their dominance over local families who accepted their protection. These warrior chiefs can largely be categorized as Celtic; however, their origins range from Gaelic to Norse-Gaelic and British. By the 14th century, there had been further influx of kindreds whose ethnicity ranged from Norman or Anglo-Norman and Flemish, such as the Clan Cameron, Clan Fraser, Clan Menzies, Clan Chisholm and Clan Grant. During the Wars of Scottish Independence, feudal tenures were introduced by Robert the Bruce, to harness and control the prowess of clans by the award of charters for land in order to gain support in the national cause against the English. For example, the Clan MacDonald were elevated above the Clan MacDougall, two clans who shared a common descent from a great Norse-Gaelic warlord named Somerled of the 12th century. Clanship was thus not only a strong tie of local kinship but also of feudalism to the Scottish Crown. It is this feudal component, reinforced by Scots law, that separates Scottish clanship from the tribalism that was found in Ancient Europe or the one that is still found in the Middle East and among aboriginal groups in Australasia, Africa, and the Americas. Civil wars and Jacobitism During the 1638 to 1651 Wars of the Three Kingdoms, all sides were 'Royalist', in the sense of a shared belief monarchy was divinely inspired. The choice of whether to support Charles I, or the Covenanter government, was largely driven by disputes within the Scottish elite. In 1639, Covenanter politician Argyll, head of Clan Campbell, was given a commission of 'fire and sword', which he used to seize MacDonald territories in Lochaber, and those held by Clan Ogilvy in Angus.
