Christian I of Denmark (1426–1481)
Born 1426 CE, died 1481 CE.
Christian I (Christiern; February 1426 – 21 May 1481) was a German noble and Scandinavian monarch under the Kalmar Union. He was king of Denmark (1448–1481), Norway (1450–1481) and Sweden (1457–1464). From 1460 to 1481, he was also duke of Schleswig (within Denmark) and count (after 1474, duke) of Holstein (within the Holy Roman Empire). He was the first king of the House of Oldenburg. In the power vacuum that arose following the death of King Christopher without a direct heir in 1448, Sweden elected Karl Knutsson king with the intent to reestablish the union under a Swedish king. Karl was elected king of Norway in the following year. However the counts of Holstein made the Danish Privy Council appoint Christian as king of Denmark. His subsequent accessions to the thrones of Norway (in 1450) and Sweden (in 1457) restored the unity of the Kalmar Union for a short period.
