Counties of Norway

From the consolidation to a single kingdom, Norway was divided into a number of geographic regions that each had its own legislative assembly or Thing, such as Gulating (Western Norway) and Frostating (Trøndelag). The second-order subdivision of these regions was into fylker, such as Egdafylke and Hordafylke. In 1914, the historical term fylke was brought into use again to replace the term amt introduced during the union with Denmark. Current day counties (fylker) often, but not necessarily, correspond to the historical areas.

• Raumafylke (Glåmdalen, Romerike, Solør)
• Heinafylke (Gjøvik, Hedmarken)
• Hadafylke (Hadeland, Land, Toten)
• Gudbrandsdal
• Østerdal

Counties under the Gulating, located in Vestlandet with the seat at Gulen:[7]

Counties under the Frostating, located in Trøndelag with the seat at Frosta:

Counties not attached to a thing:

Finnmark (including northern Troms), the Faroe Islands, the Orkney Islands, Shetland (the Shetland Islands), the Hebrides, the Isle of Man, Iceland and Greenland were Norwegian skattland ("taxed countries"), and did not belong to any known counties or assembly areas.

From the end of the 12th century, Norway was divided into several syssel. The head of the syssel was the syslemann, who represented the king locally. The following shows a reconstruction of the different syssel in Norway c. 1300, including sub-syssel where these seem established.[8]

From 1308, the term len (plural len) in Norway signified an administrative region roughly equivalent to today's counties. The historic len was an important administrative entity during the period of Dano-Norwegian unification after their amalgamation as one state, which lasted for the period 1536[9]–1814.

At the beginning of the 16th century the political divisions were variable, but consistently included four main len and approximately 30 smaller sub-regions with varying connections to a main len. Up to 1660 the four principal len were headquartered at the major fortresses Bohus Fortress, Akershus Fortress, Bergenhus Fortress and the fortified city of Trondheim.[10] The sub-regions corresponded to the church districts for the Lutheran church in Norway.

• Båhus len (later termed Bohuslän after Denmark-Norway ceded it to Sweden by the Treaty of Roskilde in 1658)
• Akershus len
• Trondheim len
• Bergenhus len (which included Northern Norway)

These four principal len were in the 1530s divided into approximately 30 smaller regions. From that point forward through the beginning of the 17th century the number of subsidiary len was reduced, while the composition of the principal len became more stable.

From 1660 Norway had nine principal len comprising 17 subsidiary len:

Len written as län continues to be used as the administrative equivalent of county in Sweden to this day. Each len was governed by a lenman.[11]

With the royal decree of 19 February 1662, each len was designated an amt (plural amt) and the lenmann was titled amtmann, from German Amt (office), reflecting the bias of the Danish court of that period.

After 1671 Norway was divided into four principal amt or stiftsamt and there were nine subordinate amt:

From 1730 Norway had the following amt:

At this time there were also two counties (grevskap) controlled by actual counts, together forming what is now Vestfold county:

• Laurvigen county
• Jarlsberg county

In 1760 Norway had the following stiftamt and amt:[12]

From 1919 each amt was renamed a fylke (plural fylke(r)) (county) and the amtmann was now titled fylkesmann (county governor).

The county numbers are from the official numbering system ISO 3166-2:NO, which originally was set up to follow the coastline from the Swedish border in the southeast to the Russian border in the northeast, but the numbering has changed with county mergers. The number 13, 16 and 17 were dropped, and the number 50 was added to account for changes over the years. The lack of a county number 13 is due to the city of Bergen no longer being its own county, and is unrelated to fear of the number 13.

In 2018, Sør-Trøndelag was merged with Nord-Trøndelag into the new county of Trøndelag, and several followed.

In 2017 the Norwegian government announced the merge of the existing 19 fylker into 11 new fylker by 2020. As a result, several government responsibilities were transferred to the new regions.[14]
