Scandinavian Relations with Ireland during the Viking Period.
CHAPTER I.
THE VIKINGS IN IRELAND (795-1014).
The Vikings made their first appearance[1] on the Irish coasts in 795 A.D., when they plundered and burned the church on Recru, or Lambay Island, near Dublin. During the next ten or twelve years Ireland seems to have been almost free from further attacks, but in 807 they descended on Inis Murray, off the Sligo coast, and from there made their way inland to Roscommon.[2] After that the raids ceased for a few years, then began again with renewed vigour on Connacht and Munster, on some of the inland counties of Leinster, and on several places along the east coast.[3]
The arrival of Turgeis[4] (O.N. Thorgestr) in Armagh, about 832, marks a new phase of the invasions. Hitherto the Vikings had come in isolated parties solely for purposes of plunder; now, however, “great sea-cast floods of foreigners” landed in every harbour, and began to form settlements in various parts of the island. Dublin was first occupied in 836, and four years later the Norsemen strengthened their position there considerably by the erection of a longphort or fortress. From their longphort at Linn Duachaill (between Drogheda and Dundalk) built in the same year, they made their way to the West and plundered Clonmacnois, while settlers from Cael-uisce, near Newry, went south and laid waste County Kildare.[5]
The power of Turgeis was not confined to the north of Ireland. His fleets were stationed on Loch Ree, the centre from which Meath and Connacht were devastated. His wife, Ota (O.N. Authr), desecrated the monastery of Clonmacnois by giving her oracular responses (a frecartha) from the high altar.[6] The tyranny of Turgeis came to an end in 845, when he was captured by Maelsechnaill, who afterwards became árd-rí, and was drowned in Lough Owel.[7]
After his death the tide of battle turned in favour of the Irish, and the Norsemen were defeated in several battles. Weakened by warfare, they had to contend in 849 with an enemy from without—the Dubh-Gaill[8] or Danes who had sailed round the south coast of England and landed in Ireland “to exercise authority over the foreigners who were there before them.” Two years after their arrival the newcomers plundered the fortresses at Dublin and Dundalk, but were attacked in the following year on Carlingford Loch by the Norsemen. In this great naval battle, which lasted three days and three nights, the Danes were finally victorious.[9]
“Amhlaoibh Conung, son of the King of Lochlann,” known in Icelandic sources as Olaf the White, came to Ireland about 852 to rule over his countrymen, and to exact tribute from the Irish.[10] According to the Fragments of Annals, he left suddenly and returned a few years later accompanied by his “younger brother, Imhar,” who may be identified with Ivarr Beinlausi (i.e., “the Boneless”) son of Ragnarr Lothbrók. Both kings ruled from Dublin, which town now gained a new importance as the seat of the Scandinavian Kings in Ireland. In 865 the Vikings extended their activities to Scotland, whence they carried off much plunder and many captives. An expedition on a larger scale was made by Olaf and Ivarr in 869, when Dumbarton, after a four months’ siege, fell into their hands. They returned in triumph to Ireland in the following year with a large number of English, British, and Pictish prisoners and ended their victorious march by the capture of Dunseverick (Co. Antrim).[11]
Olaf returned to Norway some time after this to take part in the wars there,[12] and we hear no more of him in the Irish Annals. “Imhar, King of the Norsemen of all Ireland and Britain,” did not long survive him; his death is recorded under the year 873.[13]
During the years which followed Ivarr’s death the country was comparatively peaceful, and the Irish began to enjoy a rest from fresh invasions, which lasted about forty years.[14] The Danes and the Norsemen again began to quarrel among themselves, and once more their opposing fleets met on Carlingford Lough;[15] in this battle Albann (O.N. Halfdanr), brother of Ivarr, a well-known leader of the Vikings in England, was slain. Dissensions also spread among the ranks of the Dublin Norsemen, dividing them into two hostile parties, one siding with Sitriucc, son of Ivarr, the other with a certain Sighfrith.[16] This internal strife so weakened Norse power that the Irish captured the fortress at Dublin in 902, and drove the Vikings across the sea with great slaughter.
The forty years’ rest terminated abruptly in 913, when several fleets arrived at Waterford and proceeded to ravage all Munster and Leinster. In 916 Raghnall (O.N. Rögnvaldr), grandson of Ivarr, assumed command while his brother or cousin, Sihtric Gale (also nicknamed Caoch, ‘the Blind’) came with a fleet to Cenn Fuaid, in the east of Leinster, and built a fortification there.[17] Both chiefs united forces against the árd-rí Niall Glundubh, and having defeated him in battle Sihtric entered Dublin and became king (918). In the following year the Irish under Niall made a brave stand at Kilmashogue, near Dublin, but Sihtric won a decisive victory, and Niall and twelve other kings were among the slain.[18]
