The Annals of Ulster records the arrival of two Viking fleets in Ireland in 917, one led by Ragnall and the other by Sigtrygg, both of the Uí Ímair kindred. They fought a battle against Niall Glundub in which the Irish were routed, and according to the annals Sigtrygg then "entered Áth Cliath", i.e. Dublin, which we must assume means that he took possession of it.[5] Ragnall Uí Ímair went on to Scotland[6], and then conquered York and became king there.
