The story

The parish of Ii was originally larger than the modern municipality: it included Pudasjärvi and Taivalkoski until 1639, Kiiminki, Ylikiiminki and Haukipudas until 1858. The municipality of Kuivaniemi was split off in 1919 and Yli-Ii was split off in 1924.

Kuivaniemi became a part of Ii again in 2007. When Yli-Ii was merged into Oulu, a part of it was given to Ii as an exclave. This exclave contains the Pahkakoski hydroelectric power plant.

The village of Jakkukylä and its surroundings, originally part of Yli-Ii and a part of Oulu from 2013, decided to join Ii in 2018.
