Scotlands History

Constantin II - Constantín mac Áeda (d. 952 AD)

Constantin was the grandson of Kenneth mac Alpin and son of Áed, born no later than 878 AD. He succeeded to the Scottish throne in 900 AD when his cousin Donald II died.

Constantin II reigned from 900 AD until 943 AD, when he abdicated in favour of Donald II’s son - Malcolm I. Forty three years was a very long reign in those times, only William the Lion ruled longer (49 years) until after the Union of the Crowns in 1603.

The details of Constantin II’s reign are subject to rumour and discussion. It is widely agreed that the transition from the Pictish Kingdom to the Kingdom of Alba was completed during his reign.

He countered the Viking threat by seeking peace through the marriage of his daughter to Óláfr Guðfriðsson, the Viking King of Dublin. Constantin II made an alliance with Óláfr and with the Strathclyde Britons, to invade Aethelstan’s kingdom. They were defeated by Aethelstan at the Battle of Brunanburh in 937 AD. Constantin’s son was killed in the battle.

Constantin II abdicated the throne in 943 and began a monastic life in St Andrews. He died and was buried in St Andrews in 952 AD.
