Ímar Ímar (Old Norse: "Ívarr" ; died c. 873) was a Viking leader in Ireland and Scotland in the mid-late ninth century who founded the Uí Ímair dynasty, and whose descendants would go on to dominate the Irish Sea region for several centuries. He was the son of the king of Lochlann, identified in the non-contemporary "Fragmentary Annals of Ireland" as Gofraid. The "Fragmentary Annals" name Auisle and Amlaíb Conung as his brothers. Another Viking leader, Halfdan Ragnarsson, is considered by some scholars to be another brother. The Irish Annals title Amlaíb, Ímar and Auisle "kings of the foreigners". Modern scholars use the title "kings of Dublin" after the Viking settlement which formed the base of their power. Some scholars consider Ímar to be identical to Ivar the Boneless, a Viking commander of the Great Heathen Army named in contemporary English sources who also appears in the Icelandic sagas as a son of the legendary Viking Ragnar Lodbrok.

Oslo Oslo ( , , ] ] ] ) is the capital and the most populous city in Norway. It constitutes both a county and a municipality. Founded in the year 1040, and established as a "kaupstad" or trading place in 1048 by Harald Hardrada, the city was elevated to a bishopric in 1070 and a capital under Haakon V of Norway around 1300. Personal unions with Denmark from 1397 to 1523 and again from 1536 to 1814 and with Sweden from 1814 to 1905 reduced its influence. After being destroyed by a fire in 1624, during the reign of King Christian IV, the city was moved closer to Akershus Fortress and renamed Christiania in the king's honour. It was established as a municipality ("formannskapsdistrikt") on 1 January 1838. Following a spelling reform, it was known as Kristiania from 1877 until 1925, in which year its original Norwegian name of Oslo was restored.
