In the early 840s, following their defeat of the Picts in 839, a group of Norwegians led by the sea-king Thorgest/Turgesius founded the Viking city of Dublin. Duibhlinn (Blackpool) a Viking Kingdom which eventually became Gaelicised. In English it is Dublin. Modern Dublin in Irish is Baile Átha Cliath, named after the pre-Viking monastic settlement.[1] The Norse Kingdom of Dublin was the earliest and longest-lasting Norse kingdom in Ireland.
