The story
The Senate decided to establish a parish at Posio in 1908, but the plan was delayed, in part for want of a church. Posio was finally constituted as a separate parish and municipality at the turn of 1925 and 1926, formed mainly from parts of Kuusamo, with smaller areas taken from Taivalkoski, Pudasjärvi and the rural parish of Rovaniemi. A leading figure in the campaign for the municipality's independence was the farmer Juho Aapo Miekkasaari (1862–1942).
