Akershus (Norwegian pronunciation: [ɑkəʂˈhʉːs] ) is a county in Norway, with Oslo as its main city and capital. It is named after the Akershus Fortress in Oslo. From the middle ages to 1919, Akershus was a fief and main county that included most of Eastern Norway, and from the 17th century until 2020 and again from 2024, Akershus also has a more narrow meaning as a smaller central county in the Greater Oslo Region. In 2020, the county of Akershus was merged into Viken along with the counties of Østfold and Buskerud. In 2022, the Storting voted to dissolve Viken and reestablish Akershus county. Akershus was reestablished in 2024. Originally Akershus was one of four main fiefs in Norway and included almost all of Eastern Norway. The original Akershus became a main county (Stiftamt or Stift) in 1662 and was sometimes also known as Christiania Stift. It included several subcounties (Amt or Underamt); in 1682 its most central areas, consisting of modern Oslo and Akershus, became the subcounty of Akershus within the larger main county of the same name. In 1842, the capital city of Christiania, which at the time consisted of a tiny part of modern Oslo, became a separate subcounty within Akershus main county. The main county of Akershus was disestablished in 1919, and the subcounty continued as Akershus county (fylke). During its history Akershus (sub) county ceded territory to Oslo several times; Akershus' most central and important municipality, Aker, was transferred to Oslo in 1948. The remaining county of Akershus after 1948 borders Hedmark, Oppland, Buskerud, Oslo, and Østfold; it also has a short border with Sweden (Värmland). Akershus, with a little over 614,000 inhabitants, is the second most populated county by population after Oslo. The county administration is in central Oslo, which is not part of the modern county per se.
