Saint Kentigern, also known as Saint Mungo, was a sixth century bishop and missionary who played a central role in the early Christian history of western Scotland. Born around the year 518, he was educated in the Christian faith and eventually became bishop of Strathclyde, with his ministry centred on the Clyde valley.

His episcopate was marked by political instability and opposition, leading at one point to exile in Wales. There he continued his missionary work before later returning to Strathclyde, where he resumed his pastoral care and strengthened the Church among the Brittonic peoples of the region.

Saint Kentigern is traditionally credited with establishing a Christian settlement on the site of present day Glasgow, which grew into an important centre of worship and learning. His preaching, discipline and commitment to the faith helped lay lasting foundations for Christianity in Scotland.

He died around 612 and was venerated as a saint shortly after his death. His memory remains closely linked to the city of Glasgow, whose Christian heritage is inseparable from his life and mission.
