In the history of the Vikings in Ireland we have seen how the attempt made by Turges to bring all Ireland under one ruler came to nought by his death in 845. At first this seems to have thrown the Norsemen into confusion and we hear of a series of defeats. Then, in 849, the invasions developed a new phase. Hitherto while the Irish had been weakened by much internecine warfare, their enemies had worked with one mind and heart. Now we read of 'a naval expedition of seven score of the Foreigners coming to exercise power over the Foreigners who were before them, so that they disturbed all Ireland afterwards.' This means that the Danes were now taking an active part in the invasions of Ireland, and we soon find them disputing the supremacy with the earlier Norse settlers. A full and picturesque account of the struggle is preserved for us in the second of the Three Fragments of Irish Annals copied by Dugald MacFirbis. Unfortunately the chronology of these annals is in a highly confused state and it is often difficult to trace the exact sequence of events.
When the Norsemen first saw the approaching fleet they were much alarmed. Some said it was reinforcements from Norway, but others, with keener insight, said they were Danes who were coming to harry and plunder. A swift vessel was dispatched to find out who they were, and when the steersman called out to them inquiring from what land they came and whether as friend or foe, the only answer was a shower of arrows. A fierce battle ensued, in which the Danes killed thrice their own number and carried off the women-folk and property of the Norsemen. In 851 they plundered the Norse settlements at Dublin and Dundalk, but in the next year the Norsemen attacked them in Carlingford Lough. At first the Danes were defeated, but then their leader cunningly exhorted his men to secure by their prayers and alms the patronage of St Patrick, who was incensed against the Norsemen because of the many evil deeds they had wrought in Erin. The battle was renewed and the Danes were victorious. After the battle they made rich gifts to St Patrick for 'the Danes were a people with a kind of piety: they could for a time refrain from meat and from women.' After the fight we learn that the Danes cooked their meat in cauldrons supported on the bodies of their dead foes. The Danes now helped Cerbhal, king of Ossory, against the Norsemen who were harrying Munster, and henceforward we hear again and again how the various Irish factions made use of the dissensions among the invaders to further their own ends.
Matters were further complicated by the fact that many of the Irish forsook their Christian baptism and joined the Norsemen in their plundering. These recreant Irish were known as the Gaill-Gaedhil (i.e. the foreign Irish), and played an important part in the wars of the next few years. The Gaill-Gaedhil were undoubtedly a race of mixed Norse and Gaelic stock and we must not imagine that they sprung suddenly into existence at this time. Long before this the Norsemen and the Gaels must have had considerable peaceful intercourse with one another in their various settlements, and in accordance with well-established Scandinavian custom it would seem that many of the Irish were brought up as foster-children in Norse households and must soon have learned to accept their religion and customs. There was also extensive intermarriage between Norsemen and Irish. The annals speak of several such unions, the most famous being the marriage of Gormflaith, afterwards wife of Brian Borumha, to Anlaf Sihtricsson, while in the genealogies of the Norse settlers in Iceland at the end of this century, Gaelic names are of frequent occurrence. One of the most famous of the leaders of these 'foreign Irish' was Ketill Finn (i.e. the White), a Norseman with an Irish nickname. These foreign Irish fought either by the side of the foreigners or on their own account and we have an interesting story telling how, when Vikings from Ireland made an invasion of Cheshire (c. 912), Aethelflæd, the lady of the Mercians, sent ambassadors to those Irish who were fighting on the side of the invaders, calling upon them to forsake the pagans and remember the old kindness shown in England to Irish soldiers and clergy.
The troubles between Norsemen and Danes were probably responsible for the arrival in Ireland in 853 of Amhlaeibh, son of the king of Norway, to receive the submission of the foreigners. This Amhlaeibh is Olaf the White of Norse tradition. Olaf is represented as ruling together with his brother Imhar (O.N. Ívarr). The annals are not very good authority for the relationship of the Norse leaders to one another, and it is quite possible that Ívarr is really Ívarr the Boneless, son to Ragnarr Loðbrók. Under the strong rule of Olaf and Ívarr Dublin became the chief centre of Scandinavian rule in Ireland, and the Danes and Norsemen were to some extent reconciled to one another. The Irish suffered great losses but some brave leaders were found to face the Norsemen. Cennedigh, king of Leix (Queen's County), came upon a party of them laden with booty; they abandoned the spoil and rushed upon Cennedigh with angry barbarous shouts, blowing their trumpets and many of them crying nui, nui (i.e. probably, in the old Norse speech, knúi, knúi, 'hasten on, hasten on'). Many darts and spears were thrown and at last they took to their heavy powerful swords. All was however of no avail and Cennedigh won a great victory. Less fortunate was Maelciarain, 'champion of the east of Ireland and a hero-plunderer of the foreigners.' He was expelled from his kingdom by the Leinstermen, who envied him in consequence of his many victories over the Norsemen!
The activities of Olaf and Ívarr were not confined to Ireland. In 866 Olaf paid a visit to Scotland, while in 870 both Olaf and Ívarr were present at the siege of Dumbarton. If Ívarr is Ívarr the Boneless, he must then have gone to England and taken part in the martyrdom of St Edmund. In the next year both leaders returned to Dublin with a large number of prisoners—English, Britons and Picts. In 873 Ívarr, 'king of the Norsemen of all Ireland and Britain' died, and about the same time Olaf returned to Norway, possibly to take part in the great fight against Harold Fairhair at Hafrsfjord. The Danes seem to have taken advantage of the removal of Olaf to attempt to throw off the Norse yoke. Fresh fighting took place and the Danes under Albdann, i.e. Halfdanr, king of Northumbria, were defeated on Strangford Lough in 877 with the loss of their leader.
After 877 the War of the Gaedhil with the Gaill notes a period of rest for Ireland, lasting some forty years. This is true to the extent that no large fleets of fresh invaders seem to have come to Ireland during this time—the Vikings were too busy elsewhere, both in England and the Frankish empire—but there were occasional raids from Dublin, Cork, Limerick, Waterford and other towns into various districts of Ireland, and the Norsemen were often at variance amongst themselves. Dissensions in Dublin were particularly violent and so much did they weaken Norse rule there that in 902 Dublin fell into the hands of the Irish. The Vikings were driven abroad, some going to Scotland and others to England, where they besieged Chester (v. supra, p. [57]). In the year 914 all the old troubles were renewed. Rögnvaldr, a grandson of Ívarr, fresh from a great victory off the Isle of Man, captured Waterford, and two years later Sigtryggr, another grandson of Ívarr regained Dublin. The Irish attempted resistance under the ardrí Niall Glundubh, but he fell with twelve other kings in a fight at Kilmashogue near Dublin in 919. During the next fifty years Ireland was a prey to ceaseless attacks by Norwegians and Danes alike. Towards the close of the 9th century Limerick had become a stronghold of the Norsemen in the west, and from there they made their way up the Shannon into the heart of the country. Cork was settled in the early years of the 10th century, chiefly by Danes, and from there all Munster was open to attack. Waterford and Wexford, which stood as a rule in close connexion with Dublin, served as centres of attack against Leinster. The Irish made a stout resistance under able leaders and Dublin was 'destroyed' more than once. First among these leaders stands Muirchertach 'of the leather cloaks,' son of Niall Glundubh, a hero who came forward about the year 926. His activities were unceasing. He repeatedly attacked Dublin, took a fleet to the Hebrides where he defeated the Vikings, gaining much spoil, and finally in 941 made a circuit of Ireland, from which he brought back as hostages many provincial kings, including the Norse ruler of Dublin. More famous still in Irish song and story was Cellachan of Cashel. He made war against the Vikings in Munster and for a time had the Norse kingdom of Waterford under his control. Similarly he conquered Limerick, and we find him fighting side by side with Norsemen from both these towns. During these fifty years the Norse kingdom in Dublin stood in close relation with the Scandinavian kingdom of Northumbria. Rögnvaldr, who died in 912, ruled there and so did his brothers Sigtryggr (d. 927) and Guðröðr (or Godfrey) (d. 934). The brothers left sons known respectively as Anlaf Sihtricsson and Anlaf Godfreyson. The latter took part in the great fight at Brunanburh and died in 939. Anlaf Sihtricsson was destined to a longer career. He would seem to have spent his early years in Scotland where he married king Constantine's daughter. It is uncertain whether he fought at Brunanburh, but he came to Northumbria in 941 and captured York. He was expelled from Northumbria in 944 or 945 and retired to Dublin, and the rest of his life was chiefly spent in fighting in Ireland. He was in close alliance with the Norsemen in Man and the Western Islands, and was, for some thirty years, the most powerful Norse ruler in Ireland. Then came the first great blow to Norse rule in Ireland. In 980 Maelsechlainn II, the ardrí, won a great victory at Tara over the foreigners of Dublin and the Islands in which Anlaf's son was slain. The power of the kingdom of Dublin was effectually broken. The Norsemen were compelled to liberate all the hostages in their custody, to pay a fine of 2000 oxen and to remit the tribute which they had imposed on all Ireland from the Shannon eastwards to the sea. Anlaf abandoned his authority and retired on a pilgrimage to Iona, where he died in the same year an inmate of its monastery.
In the meantime events, fraught with important consequences for Norse rule in that country, were gradually developing in a distant quarter of Ireland. In the province of Munster the Dalcassian line of princes first comes into prominence about the middle of the 10th century, and the two most famous of these princes were the brothers Mathgamhain and Brian, commonly known as Brian Borumha. Together the brothers conquered Munster in spite of the support given to the Irish by the Viking settlers, and when their success aroused Ívarr, the ruler of Limerick, they attacked him and won a great victory at Sulcoit near Tipperary (968). Limerick was captured, Mathgamhain died in 976 and Brian was soon acknowledged king of all Munster. He next became master of Leinster, but his rapid advance brought him into conflict with the ardrí and by a compact made in 998, Maelsechlainn practically surrendered the southern half of Ireland to Brian. The ruler of Dublin at this time was Sigtryggr of the Silken Beard, son of Anlaf and Gormflaith, sister of Maelmordha, king of Leinster. In 1000 Leinster with the support of the Norsemen in Dublin revolted, but Brian defeated them and captured Dublin, giving his daughter in marriage to Sigtryggr and himself marrying Gormflaith. In 1002 Maelsechlainn submitted to Brian and the latter became ardrí. There followed twelve years of peace, but Brian's marriage with Gormflaith was his undoing. Quarrelling with her husband, she stirred up Maelmordha of Leinster against him. An alliance was formed between Maelmordha and Sigtryggr, and Gormflaith dispatched embassies to all the Viking settlements in the West, summoning them to the aid of Sigtryggr in a great fight against Brian. Sigtryggr secured the help of Earl Sigurd of the Orkneys and North Scotland by promise of the kingship of Dublin. Ships came from all parts of the Viking world, from Northumbria, from Man and the Western Islands, from Scotland and the Orkneys, and even from Iceland. Dublin was fixed as the trysting-place and Palm Sunday 1014 was to be the time of meeting. Brian mustered all the forces of Munster and Connaught and was joined in half-hearted fashion by Maelsechlainn, who was really waiting to see which way the fortunes of war would turn. Brian advanced into the plain of Fingall, north of Dublin, and the two armies faced one another at Clontarf all Passion week. The Norsemen had learned by magic incantations that if the fight took place before Good Friday their chiefs would perish and their forces be routed, while if the fight took place on Good Friday Brian himself would perish but the Irish would win the day. So they waited until the Friday and then made their attack. The fight was long and the slaughter was terrible. Brian and Sigurd were themselves numbered among the slain. In the end the Norsemen were defeated and Maelsechlainn completed their discomfiture when he cut down the fugitives as they tried to cross the bridge leading to Dublin and so reach their ships. No fight was more famous in Irish history and it seems to have appealed with equally strong force to Scandinavian imagination. Clontarf and Brunanburh are the two great Viking battles which find record in Scandinavian saga, and in the story of Burnt Njal[8] we have a vivid account both of the actual battle and of the events leading up to it. Yet more interesting perhaps is the old lay preserved to us, the Song of the Valkyries, who that same day were seen in Caithness riding twelve together to a bower where they set up a loom of which men's heads were the weights, men's entrails the warp and woof, while a sword was the shuttle and the reels were arrows. They wove the web of war and foretold the fate of king Sigtryggr and Earl Sigurd as well as the sharp sorrow which would befall the Irish[9]. The Norse world was full of this and like portents and there can be no question that the Vikings were themselves conscious that the battle of Clontarf marked a very definite epoch in the history of the Vikings in the West and in Ireland more particularly. The Norsemen remained in possession of their cities, Sigtryggr continued as king of Dublin, but gradually the fortunes of the Norse settlers tended to become merged in the history of the nation as a whole and there was no further question of Scandinavian supremacy in Ireland.
