King of Denmark
In January 1448, King

Council of the Realm to Duke Adolphus of Schleswig, being the most prominent feudal lord of Danish dominions. The duke declined and recommended his nephew, Count Christian of Oldenburg. Before being elected, Christian had to promise to obey to the

King of Sweden and Norway

Meanwhile, Sweden had on 20 June 1448 elected
Karl Knutsson Bonde as king. Norway was now faced with the choice between a union with Denmark or Sweden, or electing a separate king. The latter option was quickly discarded, and a power-struggle ensued between the supporters of Christian of Denmark and Karl of Sweden. The Norwegian
Council of the Realm was divided. In February 1449, a part of the Council declared in favour of Karl as king, but on 15 June the same year, a different group of councillors paid
homage to Christian. On 20 November, Karl was crowned king of Norway in

However, the Swedish nobility now took steps to avoid war with Denmark. In June 1450, the Swedish Council of the Realm forced Karl to renounce his claim on Norway to Christian. In the summer of 1450, Christian sailed to Norway with a large fleet, and on 2 August he was crowned king of Norway in

, but this had become less and less a reality, as at the last royal successions, hereditary claims had been bypassed for political reasons. It was now explicitly stated that Norway, as well as Denmark, was an elective monarchy. The treaty stipulated that Denmark and Norway should have the same king in perpetuity, and that he would be elected among the legitimate sons of the previous king, if such existed.
Karl Knutsson became increasingly unpopular as king of Sweden, and was driven into exile in 1457. Christian achieved his aim of being elected as king of Sweden, thus re-establishing the Kalmar Union. He received the power from temporary Swedish regents Archbishop
Jöns Bengtsson Oxenstierna and lord
Erik Axelsson Tott. However, Sweden being volatile and split by factions (benefits of union being against nationalistic benefits), his reign there ended in 1464 when
Kettil Karlsson Vasa, Bishop of Linköping was installed as the next regent. Karl Knutsson was recalled as King of Sweden, although he was later exiled a second time, recalled again and died during his third term as king. Christian's final attempt at regaining Sweden ended in a total military failure at the
