Overview
Dorothea of Brandenburg (1430/1431 – 10 November 1495) was a Hohenzollern princess who became a Scandinavian queen by marriage under the Kalmar Union. She was Queen of Denmark, Norway, and Sweden from her marriage to King Christopher III in 1445 until Christopher died in 1448. As the wife of King Christian I, Dorothea was Queen of Denmark from their marriage in 1449 and Queen of Norway from 1450 until Christian's death in 1481. She was also Queen of Sweden during Christian's reign in that kingdom from 1457 to 1464. She served as interim regent during the interregnum in 1448, and as regent in the absence of her second spouse during his reign. She was the mother of two future kings of Denmark: John (r. 1481–1513) and Frederick I (r. 1523–1533).
Early life
Dorothea was born in 1430 or 1431 to John, Margrave of Brandenburg-Kulmbach, and Barbara of Saxe-Wittenberg (1405–1465). She had two sisters: Barbara (1423–1481), who became Marchioness of Mantua, and Elisabeth (14??-1451), who became Duchess of Pomerania.
From about the age of eight, she lived in Bayreuth, where her father was ruler. In 1443, Christopher of Bavaria, the newly elected King of Denmark, Sweden and Norway, inherited Oberpfalz close to Bayreuth, and a marriage was suggested between Christopher and Dorothea to secure her father's support for Christopher's power over his German domain. The engagement was proclaimed prior to the application of Papal dispensation for affinity in February 1445, which was approved 10 March.
Marriage to Christopher of Bavaria
On 12 September 1445, the wedding ceremony was conducted between Christopher and Dorothea in Copenhagen, followed by the coronation of Dorothea as queen. The King had financed it with a special tax in all three Kingdoms, and the occasion is described as one of the most elaborate in Nordic Medieval history. The festivities lasted for eight days and was attended by the Princes of Braunschweig, Hesse and Bavaria and envoys of the Hanseatic League and the Teutonic Order as well as the nobility of Denmark, Sweden and Norway. Dorothea made her entrance in the city escorted by noblemen from all three Kingdoms dressed in gold riding on white horses, and crowned Queen of Denmark, Sweden and Norway by bishops from all three Kingdoms with the golden crown from the Vadstena Abbey.
