"Most of those who first raided Ireland were Norsemen (from Norway), who the Irish called the fionngaill (“fair strangers”), to distinguish them from the other nation of Vikings, the Danes or dubhgaill (“dark strangers”)*. The first great Viking lord in Ireland was Turgeis (Thorgis?). He arrived in 839, leading “a great sea-cast flood of foreigners into Eire, so that there was not a point (along the coast) thereof without a (Viking) fleet”. Turgeis raided deep into Ireland, attacking the chief religious center of the land, Armagh; where he drove out the Bishop, who fled with relics of St. Patrick. Turgeis established himself as lord of Dublin (the “Dark Pool”), previously a Christian ecclesiastical settlement but which now became a Norse military settlement. Dublin was perfectly situated at a ford of the River Liffey, and possessed of a fine harbor for trade and the anchorage of Viking longships."
