University of Oslo.

The University of Oslo is a public research university located in Oslo, Norway. It is the oldest university in Norway. Originally named the Royal Frederick University, the university was established in 1811 as the de facto Norwegian continuation of Denmark–Norway's common university, the University of Copenhagen, with which it shares many traditions. It was named for King Frederick VI of Denmark and Norway, and received its current name in 1939. The university was commonly nicknamed "The Royal Frederick's" before the name change, and informally also referred to simply as Universitetet.
