[1] The festivities lasted for eight days and were 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.

[1] On 15 September, she was granted dowers in all three Kingdoms: Roskilde, Ringsted, Haraldsborg, and Skioldenses in Denmark; Jämtland in Norway, and Örebro, Närke, and Värmland in Sweden.

[1] Queen Dorothea left for Sweden with the King in January 1446, where they visited Vadstena Abbey and her dower Örebro.

[1] In January 1448, King Christopher died childless, which resulted in a succession crisis that immediately broke the Kalmar Union of the three Kingdoms.

The newly married couple's ambition was to have Christian crowned in Sweden and Norway as well, and thereby reunite the shattered Kalmar Union.

The task to win back Sweden was more difficult, and Dorothea waged a long campaign to recruit followers among the Swedish clerics and nobility.

Her message to her followers was that their elected king Charles VIII, as her former Lord Constable and subject, was to be regarded as a usurper and a traitor who had broken his vow by depriving her, his former queen, of her dower lands in Sweden.

[1] In February 1457 her campaign succeeded when the rebellion of Archbishop Jöns Bengtsson Oxenstierna deposed Charles VIII, who fled to Germany.

[1] In 1475, she traveled to Italy and visited her sister Barbara in Mantua, and Pope Sixtus IV in Rome, and formally applied to have Sten Sture excommunicated.

[1] Following her visit to Rome in May 1475, Sixtus IV subsequently issued a bull to King Christian permitting the establishment of a university in Denmark.

When King Christian acquired Holstein and Schleswig in 1460 and was unable to pay, she loaned him the amount necessary to buy these domains and incorporate them into Denmark.

[6] Dorothea continued with her ambition to reunite the Kalmar Union of the Nordic Kingdoms, now by having her son elected king of Sweden rather than her spouse by ousting the Swedish regent through an excommunication.

[1] In January 1482, she informed her son the king of this plan, and in 1488 she made a second trip to her sister Barbara in Mantua, meeting with Frederick III in Innsbrück, and Pope Innocent VIII in Rome.
