Mackenzie stated that this treaty dates to the year 1156 and marks the date on which the South Isles passed permanently from the dominion of the Kings of Mann. Sources Chronicle of Mann The Chronicle of Mann describes how Páll was an ally of Olaf the Black, brother to Reginald, King of Mann and the Isles. The chronicle relates that Reginald gave Olaf the Outer Hebridean Isle of Lewis. The island was, however, thinly populated and the land was mostly unfit for cultivation. After a while Olaf determined that he could no longer support himself and his followers; he then asked his brother for further lands.
