Reigned from 889 to 900. Usurped power by deposing his cousins Giric and Eochaid. He was the frist ruler called Ri Alban, or "King of Scotland." Even so, the Norse made inroads into his kingdom, who had established themselves in the Western Isles, and were now attempting to dominate the north of Scotland, as well. Donald died in battle at Forres and is buried on Iona.
