Medieval bishops of the Catholic Church were also de facto secular leaders of the country until the end of the 13th century.
When Finland became a separate grand duchy, the then bishop of Turku was designated as an archbishop in 1817.
According to legends, the English-born Henry arrived in Finland with King Eric IX of Sweden during the First Swedish Crusade, later suffering martyrdom in the 1150s.
His position as Bishop of Finland is, however, totally unhistorical, and not claimed even by legends.
The title of the see was changed to the Archbishop of Turku and Finland.
