Kenneth II
For the first six years of his reign, Kenneth had a dispute with Amlaíb mac Illuilb, the younger brother and heir of of Kenneth's predecessor, Culen. Eventually in 977, Amlaíb died and the dispute between him and the king was over. It was said that Kenneth ordered the murder of Amlaíb. Kenneth would then rule the kingdom effectively until his death in 995 at the age of 63. He was succeded by Constantine III, the son of Kenneth's predecessor.
