Historical Timeline
Key moments in Oslo's history.
The Oslofjord region was a major centre of Viking activity. Many of the extraordinary Viking ship burials found at Gokstad, Tune, and Oseberg (now on display at the Museum of the Viking Age) date from this era. The earliest settlement at Oslo was founded around 1000 AD.
Oslo was founded around 1000 AD, traditionally attributed to Harald Hardrada. In 1048, King Harald Hardrada officially established the city. Oslo became a bishopric in 1070 and grew as an ecclesiastical and trading centre.
In 1299, King Haakon V moved the Norwegian capital from Bergen to Oslo. He began construction of Akershus Fortress around 1300 to defend the city. Oslo grew as a trading town under Hanseatic influence.
In 1624, Oslo burned to the ground for the third time. King Christian IV of Denmark (Norway was then under Danish rule) decided to rebuild the city to the west of the original site, under the protection of Akershus Fortress, and renamed it Christiania after himself.
Christiania grew under Danish rule as Norway's administrative capital. The University of Oslo was founded in 1811. Norwegian culture, literature, and national identity began to flourish despite foreign rule.
Norway broke from Denmark in 1814 and entered a union with Sweden. The Norwegian Constitution was signed at Eidsvoll on May 17, 1814 - Norway's National Day. Karl Johans Gate was developed as the new city's grand boulevard. The city was renamed Kristiania (and briefly back to Christiania) before finally returning to Oslo in 1925.
Norway dissolved its union with Sweden in 1905 and became a fully independent nation. The city was officially renamed Oslo in 1925, reclaiming its medieval Norse name. Oslo City Hall construction began in 1931.
Nazi Germany invaded Norway on April 9, 1940. Oslo was occupied for five years. The Norwegian Resistance Museum at Akershus Fortress documents this period. The Nobel Peace Prize was not awarded during the occupation years.
Norway emerged from WWII and rebuilt rapidly. The discovery of North Sea oil in 1969 transformed Norway into one of the world's wealthiest nations. Oslo became a major diplomatic and cultural capital, home to the Nobel Peace Prize and host of the 1952 Winter Olympics.
