 Like the Northern Isles, the Outer Hebrides and the northern Inner Hebrides were predominantly Pictish in the early 9th century.By contrast, the southern Inner Hebrides formed part of the Gaelic kingdom of Dál Riata.The obliteration of pre-Norse names in the Outer Hebrides and in Coll, Tiree and Islay in the Inner Hebrides is almost total and there is little continuity of style between Pictish pottery in the north and that of the Viking period.
