Constantine of Strathclyde was a 6th-century monarch and saint who ruled the Brittonic kingdom of Alt Clut, a realm later called Strathclyde. As the son of King Riderch Hael, he eventually succeeded his father to the throne. According to hagiographical traditions, he later abdicated his royal position to pursue a religious life as a clergyman. While his historical existence is debated due to a lack of contemporary genealogies, he remains a significant figure in religious narratives associated with the early Christianization of the region.
Life and legend
Tradition suggests that Constantine was converted to Christianity by Saint Columba. Following his reign, he reportedly stepped down from his position as king in 612 AD to serve as a monk and priest. He is described as a missionary who traveled to Ireland and England to spread the faith. He passed away around 640 AD, though some scholars suggest his biography may have been a literary creation to provide a narrative for early local figures.
Veneration
The Greek Orthodox Church recognizes him as a saint, celebrating his feast day on 11 March. In the Glasgow area, an early church in Govan was dedicated to him. A sarcophagus, potentially used to hold his relics, has been identified in the Govan churchyard. Because of his name, he is sometimes conflated with other figures, including a Cornish saint or later Scottish kings.
