If instead of the Norse the previously uninhabited Iceland was settled by the Irish? The Norse stated Irish monks were there before they arrived but they were in small numbers.
How would it have developed and would it have likely fallen under the sphere of England/Britain?
Because Iceland's settlement was so small, the Norse intermarried with the some of indigenous Celts, resulting in a hybrid Nordic-Celtic culture. I doubt England/Scotland will be interested in a campaign to conquer Iceland unless circumstances force them to do so.
