The city and municipality used the name "Kristiania" until 1 January 1925 when the name changed to "Oslo". Oslo was the name of an eastern suburb - it had been the site of the city centre, until the devastating 1624 fire. King Christian IV of Denmark ordered a new city built with his own name; Oslo remained a poor suburb outside the city border. In the early-20th century, Norwegians argued that a name memorialising a Danish king was inappropriate as the name of the capital of Norway, which became fully independent in 1905.
