Aker, Norway

Aker municipality was in terms of population by far the largest municipality of Akershus county and surrounded the capital city of Christiania (renamed Oslo in 1925) until 1948; Aker was 27 times larger than the capital it surrounded. In the late 19th century Aker ceded some of its territory to Christiania, and in 1948 Aker merged completely with Oslo municipality to create the modern, vastly enlarged Oslo municipality. The merger was unpopular in Aker, which at the time was an affluent suburban community.
