The failure of Haakon IV's great expedition at Largs in October 1263 led to a vigorous Scottish counter‐attack, which subdued the Inner Hebrides. On 2 July 1266 Magnus IV of Norway, Haakon's successor, signed the treaty of Perth with Alexander III of Scotland. In return for four payments of 4,000 marks and a tribute of 100 marks in perpetuity, the Norwegians surrendered sovereignty over all the Western Islands and the Isle of Man. They retained possession of Orkney and Shetland.
