It is the largest of the Small Isles, and the 15th largest Scottish island, but is inhabited by only about thirty or so people, all of whom live in the hamlet of Kinloch on the east coast. The island has been inhabited since the 8th millennium BC and provides some of the earliest known evidence of human occupation in Scotland. The early Celtic and Norse settlers left only a few written accounts and artefacts. From the 12th to 13th centuries on, the island was held by various clans including the MacLeans of Coll. The population grew to over 400 by the late 18th century but was cleared of its indigenous population between 1826 and 1828. The island then became a sporting estate, the exotic Kinloch Castle being constructed by the Bulloughs in 1900. Rùm was purchased by the Nature Conservancy Council in 1957.
