John of Islay

Some modern historians nevertheless count John as the first of the later medieval lords of the Isles, although this rather broad Latin style corresponds roughly with the older Gaelic title Rí Innse Gall, in use since the Viking Age. For instance, the even more similar Latin title dominus de Inchegal, applied to Raghnall Mac Somhairle in the mid-12th century. In fact John is actually styled Rí Innsi Gall or King of the Isles shortly after his death in a contemporary entry in the Irish Annals of Ulster. Clan Donald considers the title "Lord of the Isles" to have been in use at least since Angus Mor Macdonald, who died in 1293, and the title "King of the Isles" in use since Somerled, the Norse-Gael who forged the Kingdom of the Isles in the 12th century.
