In 1014, the chief magnate of the Hebrides was Earl Gilli. He held aloof from the great muster of Norsemen from many regions that came to Clontarf to win the sovereignty of Ireland for Earl Sigurd of the Orkneys. From 1041 till 1064, the Hebrides appear subject to the Orkney earl Thorfinn. During this time, the islands supplied forces to Harald Hardrada, king of Norway, for an invasion of England. After this time, there are indications that the predominance of the Orkney earls was replaced in the Hebrides by that of the kings of the Isle of Man. Later on, the kings of Man are seen to occupy a middle position of authority between the kings of Norway and the local rulers of the Hebrides. In the title of the bishops of Sodor and Man, the name Sodor is an abbreviation for Sudreyar, "the southern isles," this being the ordinary Norse name for the Hebrides, in contradistinction to the northern isles of Orkney and Shetland.
In 1098, Magnus Barefoot, king of Norway, came with a fleet and re-established the somewhat shaky Norwegian sovereignty over the Orkneys, the Hebrides, Cantire, and the Isle of Man. Four years later, in 1102, he again visited these dominions and was received without opposition. The following year, 1103, king Magnus landed in eastern Ulster and was cut off and slain.
In 1134, a young Hebridean named Gilla Críst, claiming to be a son of Magnus, became king of Norway under the name of Harald Gilli. About this time, the most prominent magnate in the Hebrides was named Holdbodi, who lived in the island of Tiree. The Norse documents dealing with these times and with the succeeding century never suggest that the masters of the Hebrides use any language but Norse, though some of them bear Gaelic names; and the same documents apply the name Scots to the mainlanders only, never to the people of the islands.
In 1157, we find the first mention of a ruler named Sumarlidi, who dwelt on the mainland of Argyleshire. In Irish he is called Somhairlidh, and in recording his death in 1164, the Annals of Tighernach entitle him "king of the Hebrides and Cantire." Fordun's Chronicle calls him "king of Argyle." Sumarlidi was in fact the founder of a new Norse kingdom of the Hebrides and Argyle, which lasted from his time, about 1150, until 1499, when the last king of his line was captured by the king of Scotland and hanged, along with his son and grandsons, on the Boroughmuir at Edinburgh. Sumarlidi was killed in 1164, in an attempt to invade the mainland south of the Clyde.
This Sumarlidi was the ancestor of the families of MacDomhnaill (MacDonnell, MacDonald), Mac Dubhghaill (MacDugall, MacDowell, etc.), and Mac Ruaidhri (MacRory). More than two centuries after his time, when many of his descendants had settled in Ireland, a pedigree was forthcoming to trace his descent from one of the Three Collas who overthrew the ancient kingdom of Ulster in the fourth century. In Scotland, his descendants seem to have been provided with another pedigree, which established their descent from Fergus, son of Erc, who founded the Irish kingdom in Scotland. Ultimately a blend of the two pedigrees found acceptance, and no doubt there are many MacDonnells and MacDugalds and MacRorys who believe in it. Apart from its other weak points, this genealogy of the race of Sumarlidi is too short by about nine generations or three centuries.
Scottish writers in general show a remarkable shyness in dealing with this kingdom of Argyle and the Hebrides, and the highest title they are accustomed to accord to its rulers is that of "Lords of the Isles." In contemporary Norwegian and Irish records, the title is always "king."
Internal dissensions in Norway left the Hebrides practically independent for half a century after the rise of Sumarlidi. In 1210, when these dissensions were composed, the kings of the Hebrides and the Isle of Man made haste to Norway and renewed their fealty to King Ingi. On the death of this king without heir in 1217, and the renewal of the disorders of Norway, the Hebrides again fell away from their allegiance. In 1224, Hakon, of doubtful paternity, was accepted as king of Norway. At this time Alan of Galloway threatened to extend his dominion over the Hebrides and the Isle of Man. King Hakon found a Hebridean adventurer named Ospak, who had long lived in Norway and had taken part in the wars of the factions. He appointed this Ospak king over the Hebrides. For greater prestige he re-named Ospak after himself, Hakon, and sent him with a small fleet in 1230 to bring the Hebrides under his authority. After a partial success, Ospak fell sick and died. Fresh troubles breaking out in Norway prevented Hakon from following up his Hebridean policy and encouraged the king of Scotland, Alexander II, to aim at the recovery or annexation of the islands. To this end, in 1242, Alexander sent an embassy to Norway offering to buy out the Norwegian claims. This proposal was rejected by Hakon. It was afterwards renewed and again rejected.
In the meantime, Alexander, stronger by land than by sea, made war on the Hebridean kings for the possession of Argyle, Arran, and Bute, and appears to have gained a strong foothold in those parts. In 1248 a dispute arose between two of Sumarlidi's descendants over the kingship. Both went to Norway to seek a decision from King Hakon. Hakon disliked decisions, and was content to keep the claimants for a year in Norway. Next year Alexander of Scotland renewed his efforts. He sent a third offer of purchase to Hakon and at the same time made open preparations for conquest. He also endeavoured to win over Jon, king of the Hebrides, from his allegiance to Norway. Jon held out, and in the midst of the preparations for invasion, Alexander died (1249).
He was succeeded by his son, Alexander III, already spoken of in this lecture, last of the Dalriadic kings in the direct line. When that interesting coronation ceremony in Latin and Gaelic was performed, Alexander III was only nine years of age. During his minority, the connection between Norway and the Hebrides was maintained. In 1252, Archbishop Sorli of Drontheim in Norway, being then at Rome, assisted in the consecration of a bishop named Rikard for the Hebrides. In 1253, Jon and Dubhghall, joint kings of the Hebrides, went again to Norway to assist king Hakon in a war against Denmark.
In 1261, Alexander III, having come of age, took up his father's policy of annexing the Norse dominions adjoining Scotland, and sent a fresh embassy to Norway. Failing to make terms, he began next year the invasion of the islands. He reoccupied Bute and Cantire, and sent a marauding expedition under the Earl of Ross into the island of Skye. King Jon of the Hebrides wrote informing Hakon of what was going on, and from the sequel we may judge that he held out no hope of being able to resist Alexander. Hakon called together his council, some of whom proposed to relinquish the islands to Scotland, but the king ordered that an expedition at full strength should be raised next year. It was always the next opportunity with King Hakon. Next year, 1263, he spent the time until the end of July in making ready. In the meantime, King Jon made terms for himself with Alexander and transferred his allegiance to Scotland. Hakon made a slow progress with his fleet through the islands and reoccupied part of Cantire and also Arran and Bute. Alexander, relying on the approach of winter, re-opened negotiations and kept them going till the arrival of the equinoctial gales. On October 1, Hakon's fleet was partly scattered by a violent storm. Some ships were driven on the coast of Ayrshire. Here a trifling encounter took place with the Scottish forces. It has been magnified in Scottish histories into the battle of Largs, in which, we are told, 16,000 Norwegians were slain.
