Editing Akershus (section)

==History==
Akershus became a fief in the 16th century, and then also included the current counties of [[Hedmark]], [[Oppland]], [[Buskerud]], and [[Oslo]], as well as the municipalities of [[Askim]], [[Eidsberg]], and [[Trøgstad]] in the county of [[Østfold]]. In 1662, Akershus became an [[Amt (administrative division)|''Amt'']], and in 1685, Buskerud was separated from Akershus and became an ''Amt'' of its own. In 1768, Hedmark and Oppland were also separated from Akershus to become ''Oplandenes Amt'' (and Askim, Eidsberg, and Trøgstad were transferred to Østfold). In 1842, the city of Christiania (Oslo) was made a separate ''Amt'', as well. In 1919, the term ''Amt'' was changed to ''Fylke''. In 1948, Aker, the greatest and the most populous municipality of Akershus, was transferred to the county of Oslo.
