Founded in the year 1040 as Ánslo, and established as a 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 reduced its influence, and with Sweden from 1814 to 1905 it functioned as a co-official capital.
