 This military campaign may have been undertaken to counter the Dubliners' attempt to install Gofraid mac Amlaíb, King of the Isles to the kingship of Dublin, as recounted by the thirteenth- to fourteenth-century "Chronicle of Mann".The record of events during the mid part of the twelfth century suggests that Leinster-based overkings of Dublin enjoyed the cooperation of the indigenous leaders of Dublin, and the emergence of the Meic Torcaill during this period may well fit into such a context.When an indigenous ruler was not to be found, however, the Dubliners seem to have sought leadership from the Isles, rather than endure a non-Leinster overking, as evidenced by the attempt to install Gofraid.
