In the first half of the 9th century, the geopolitical situation in Dál Riada deteriorated. Almost the entire territory of the kingdom was mountainous, and was filled with uneasy terrain. Kenneth's realm lay between the powerful Kingdom of Strathclyde in the south and the Druim Alban mountain ridge in the east. It was difficult to pass through the provinces of Dál Riada, most of the land was infertile, and the kingdom had lost its western territories in the Hebrides to the Vikings, who had settled in the area and were raiding the borders of Dál Riada. These conditions may have forced Kenneth to attack the Picts.
