The parish of Fjældberg was established as a formannskapsdistrikt on 1 January 1838. According to the 1835 census the parish had a population of 2,986 at the time.[3] In 1855, the neighboring municipality of Eid was incorporated into Fjelberg, increasing its population to 4,794.[4]
In 1865, the parish of Vikebygd (population: 1,062) in the southwestern part of the municipality was separated from Fjelberg and merged with a part of neighboring Finnaas Municipality to create the new Sveen Municipality. On 1 January 1898, the southern part of the island of Huglo (population: 117) was transferred from Fjelberg to the neighboring Stord Municipality. On 1 July 1916, the southern (mainland) part of Fjelberg (population: 1,715) was split off to form the new Ølen Municipality, leaving Fjelberg with 1,926 inhabitants.[4]
On 1 January 1965, as part of the nationwide merging of municipalities as suggested by the Schei Committee, Fjelberg municipality was dissolved. Fjelberg municipality was merged with neighboring Kvinnherad Municipality, part of Skånevik Municipality, and most of Varaldsøy Municipality to form the new (much larger) Kvinnherad Municipality. Prior to the merger, Fjelberg had a population of 2,308, and after the merger, the new municipality had nearly 10,000 residents.[4]
Name
The municipality (originally the parish) is named after the island of Fjelbergøya (Old Norse: Fjǫlbyrja) since the first Fjelberg Church was built there. The first element is the prefix fjǫl- which means "much" or "many". The last element is byrr which means "fair wind" or "favorable wind" (in terms of sailing). Thus it is a place with many kinds of good winds for sailing.[5]
The municipal council(Heradsstyre) of Fjelberg was made up of 21 representatives that were elected to four year terms. The party breakdown of the final municipal council was as follows:
