Óengus I

Who was Óengus I?

Óengus son of Fergus, was king of the Picts from 732 until his death in 761. His reign can be reconstructed in some detail from a variety of sources.

Óengus became the chief king in Pictland following a period of civil war in the late 720s. During his reign, the neighbouring kingdom of Dál Riata was subjugated and the kingdom of Strathclyde was attacked with less success. The most powerful ruler in Scotland for over two decades, he was involved in wars in Ireland and England. Kings from Óengus's family dominated Pictland until 839 when a disastrous defeat at the hands of Vikings began a new period of instability, which ended with the coming to power of Cináed mac Ailpín.
