Domnall mac Causantín (Donald) II -, King of the Picts, or of Alba

Notes:

Biography:
Donald is called Dásachtach, "the Madman", by the Prophecy of Berchán, a Middle Irish Poem written around the 12th century but supposedly older. He was King of the Picts (Northeast Scotland) or of Alba (most of Scotland) from 899 until his death in 900. From the Chronicle of the Kings of Alba:
Doniualdus son of Constantini held the kingdom for 11 years [889–900]. The Northmen wasted Pictland at this time. In his reign a battle occurred between Danes and Scots at Innisibsolian where the Scots had victory. He was killed at Opidum Fother [modern Dunnottar] by the Gentiles.
From Wikipedia:
The change from king of the Picts to king of Alba is seen as indicating a step towards the kingdom of the Scots, but historians, while divided as to when this change should be placed, do not generally attribute it to Donald in view of his epithet. The consensus view is that the key changes occurred in the reign of Constantine II (Causantín mac Áeda), but the reign of Giric has also been proposed.

Biography:
He was King of the Picts (Northern and Eastern Scotland) from 852-877). His reign saw a rise in invasions from the Vikings based in Ireland, Northumbria and northern Britain. Constantine died in one of those raids and was buried on the island of Iona in the Inner Hebrides.

Biography:
Kenneth, King of the Picts (north and east Scotland) 843-858, is often thought of as the first King of Scotland but this is not the case. That title really goes to his grandson Constantine II. What is true is that he came to power after a very complicated succession and is at the head of a dynasty that led Scotland for hundreds of years. In the battle of 839 against the Vikings, the King of the Picts and all his possible successors were killed. Kenneth was one of four contenders to the throne. Sometime between 843 and 848 he defeated the last of the contenders to become the undisputed King of the Picts. During his reign the Vikings continued to make gains in the surrounding regions.

Died:
He died of a brain tumor.

Biography:
Almost all that is know of Alpín comes from the Chronicle of Kings of Alba: "[Alpín] was killed in Galloway, after he had entirely destroyed and devastated it. And then the kingdom of the Scots was transferred to the kingdom [variant: land] of the Picts."
