The parish of Skaatø (later spelled Skåtøy) was established as a municipality on 1 January 1882 when it was separated from the larger municipality of Sannidal. Initially, the new municipality had 3,907 residents. On 1 January 1891, an area of Skåtøy (population: 809) that was adjacent to the growing town of Kragerø was annexed and transferred from Skåtøy to Kragerø. During the 1960s, there were many municipal mergers across Norway due to the work of the Schei Committee. On 1 January 1960, the municipality of Skåtøy (population: 3,208) was merged with the neighboring Sannidal Municipality (population: 2,604) and the neighboring town of Kragerø (population: 4,638).[5]
Name
The municipality (originally the parish) is named after the island of Skåtøy (Old Norse: Skotøy) since the first Skåtøy Church was built there. The first element is identical to the word skot which means "overhang" or "projection of land". The last element is identical to the word øy which means "island".[6]
Historically, the name of the municipality was spelled Skaatø. On 3 November 1917, a royal resolution changed the spelling of the name of the municipality to Skaatøy. The letter y was added to the end of the word to "Norwegianize" the name (ø is the Danish word for "island" and øy is the Norwegian word).[7] On 21 December 1917, a royal resolution enacted the 1917 Norwegian language reforms. Prior to this change, the name was spelled Skaatøy with the digraph "aa", and after this reform, the name was spelled Skåtøy, using the letter å instead.[8][9]
The municipal council(Herredsstyre) of Skåtøy was made up of representatives that were elected to four year terms. The tables below show the historical composition of the council by political party.
