 The Norse held sway in the Small Isles from 833 until the Treaty of Perth in 1266. The Macsorley clan held tutelage in the later period of Norse rule from at least 1240, and possibly a century earlier. The only direct evidence of a Norse presence on Rùm to date is a piece of carved narwhal ivory unearthed at Bagh na h-Uamh in 1940.
