The parish of Mo was established as a municipality on 1 January 1838 (see formannskapsdistrikt law). In 1879, there was a small border adjustment where a part of Laardal Municipality (population: 6) was transferred to Mo Municipality. During the 1960s, there were many municipal mergers across Norway due to the work of the Schei Committee. On 1 January 1964, Mo Municipality (population: 1,658) and Lårdal Municipality (population: 1,929) were merged to form a new municipality called Tokke.[4][5]
Name
The municipality (originally the parish) is named after the old Mo farm (Old Norse: Mór) since the first Mo Church was built there. The name is identical with the word mór which means "heath" or "moorland".[6]
The municipal council(Herredsstyre) of Mo was made up of 21 representatives that were elected to four year terms. The tables below show the historical composition of the council by political party.
