Västmanland County in the context of "Kvicksund"

Län (Swedish, IPA: [ˈlɛːn] ), len (Danish, IPA: [leːn]), lääni (Finnish, IPA: [ˈlæːni]) and len (Norwegian, IPA: [leːn]) refer to the administrative divisions used in Sweden and previously in Denmark, Finland and Norway. The provinces of Finland were abolished on 1 January 2010. In Norway, the term was in use from 1308 and in Denmark from the beginning of the 13th century. As of 19 February 1662 the len of Denmark-Norway were converted into amt.

They are also sometimes used in other countries, especially as a translation of the Russian word volost. During the period when Finland was a part of the Russian Empire (1809–1917), when Russian was made an official language alongside Swedish, it was synonymous with the word guberniya.

Örebro County (Swedish: Örebro län) is a county or län in central Sweden. It borders the counties of Västra Götaland, Värmland, Dalarna, Västmanland, Södermanland and Östergötland.

Dalarna County (Swedish: Dalarnas län) is a county or län in central Sweden (Svealand). It borders on the counties of Uppsala, Jämtland, Gävleborg, Västmanland, Örebro and Värmland. It also borders on the Norwegian counties of Hedmark and Trøndelag to the west. It was formerly known as Kopparberg County (Swedish: Kopparbergs län) until the name was changed to that of the provincial region on 1 January 1997. The province of Dalarna is slightly larger than the county, as the westernmost part of Ljusdal Municipality belongs to it. Prince Gabriel, the son of Prince Carl Philip, is Duke of Dalarna.

The term Dalarna County is mainly used for administrative purposes; it is further divided into municipalities (kommuner). Dalarna County encompasses nearly all of the cultural and historical province of Dalarna (literally, "the valleys"). For the most part sparsely populated and with extensive tracts of wilderness, Dalarna County is almost as large as Belgium in terms of land area.
