Cause

Somerled, King of Kintyre, Argyll and Lorne, sought to expand his power at the expense of Godred II, King of Mann and the Isles. Tensions between Norse and Celtic rulers of the western seaways provided the backdrop for Somerled's military campaign against Godred's domain.

Event

Somerled sailed a fleet of 53 birlinns into Ramsey Bay and attacked Godred II's forces on the Isle of Man. Godred II was unable to repel the assault and fled the island to seek support from England, Scotland, and Norway, leaving Somerled in control of the Isle of Man.

Consequence

Somerled seized the Kingdom of Mann and the Isles following his victory, later travelling to Norway to obtain recognition from King Inge. He held the title until his death at the Battle of Renfrew in 1164, after which Godred II was reinstated as king.
