Early Scandinavian Dublin
In the year 795 Vikings (probably of Norwegian origin) raided islands off the coast of Ireland for the first time. This was the beginning of a new phase of Irish history, which saw many native communities – particularly ecclesiastical ones – relocate themselves on the continent, or further afield in places like Iceland and the Faroe Islands, to escape the pagan marauders. For about two decades the invaders confined their activities to coastal settlements; raiding parties were generally small and there is no evidence that any of them wintered in Ireland during this early phase of "hit-and-run" activity. Typically the Vikings would arrive at a settlement without warning, plunder what goods and people they could – the people were usually sold as slaves, though notable personages were often held for ransom – before retreating to their Scandinavian or British bases. This period lasted from 795 until 813, after which there occurred a hiatus of eight years.
It is now thought that these early raids were launched directly from southwest Norway, and that during the period of calm (814–820) the Norwegian Vikings were occupied in northern Britain, laying the foundations of a new kingdom referred to in Irish sources as Laithlind (later Lochlainn). Laithlind was once thought to be in Norway but it is now identified with Viking settlements in the British Isles, especially those in Scotland and the Isle of Man.
Viking metal
Viking metal features the Vikings as its subject matter and for evocative imagery. The Vikings were Northern European seafarers and adventurers who, during the Middle Ages, relied on sailing vessels such as longships, "knerrir", and "karvi" to explore, raid, pirate, trade, and settle along the North Atlantic, Baltic, Mediterranean, Black Sea, and Caspian coasts and Eastern European river systems. The Viking Age is generally cited as beginning in 793, when a Viking raid struck Lindisfarne, and concluding in 1066, with the death of Harald Hardrada and the Norman conquest of England. During this two-hundred-year period, the Vikings ventured west as far as Ireland and Iceland in the North Atlantic and Greenland and what is now Newfoundland in North America, south as far as the Kingdom of Nekor (Morocco), Italy, Sicily, and Constantinople in the Mediterranean, and southeast as far as what are now Belarus, Russia, and Ukraine in Eastern Europe, Georgia in the Caucasus, and Baghdad in the Middle East.
