The municipality was established on 31 December 1893 when it was split off from the large municipality of Oddernes to form a separate municipality of its own. Initially, Randesund had a population of 1,133. During the 1960s, there were many municipal mergers across Norway due to the work of the Schei Committee. On 1 January 1965, the municipality of Randesund (population: 1,672) was merged with the neighboring municipalities of Tveit (population: 2,802) and Oddernes (population: 18,668) and with the town of Kristiansand (population: 27,100) to form a new, much larger municipality of Kristiansand.[3]
Name
The municipality (originally the parish) is named after the old Randøen farm (Old Norse: Rǫnd) which was located on an island of the same name. The first element is derived from the word rǫnd which means "edge" or "rim". The last element of the name is identical to the word sund which means strait or "sound".[4][2] Historically, the name of the municipality was spelled Randøsund. On 3 November 1917, a royal resolution changed the spelling of the name of the municipality to Randesund.[5]
The municipal council(Herredsstyre) of Randesund 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.
