Christian I of Denmark

Following the death of King Christopher III, the Danish Council elected Christian of Oldenburg as king. This established the Oldenburg dynasty, which would rule Denmark for over four centuries.

Christian I was crowned King of Norway in Trondheim, formalizing the union between Denmark and Norway. This union lasted until 1814, making Norway a Danish dominion for centuries.

Christian I was elected King of Sweden, briefly restoring the Kalmar Union. His rule in Sweden was contested, leading to rebellion and his eventual deposition in 1464.

To secure a dowry for his daughter Margaret's marriage to James III of Scotland, Christian I pledged the Orkney and Shetland islands. The pledge was never redeemed, and the islands became permanently part of Scotland.

Christian I issued a charter establishing the University of Copenhagen, the first university in Denmark. Modeled on the University of Cologne, it became a center of learning and the oldest university in the country.
