Through Jutes and England

The youngest daughter of Valdemar IV of Denmark, Margaret was born at Søborg Castle. She was a practical, patient administrator and diplomat, albeit one of high aspirations and a strong will, who intended to unite Scandinavia forever into one single entity with the strength to resist and compete against the might of the Hanseatic League. In 1363, aged ten, Margaret married Haakon VI. In 1370, they had a son, Olaf. Following the deaths of her husband and son, Margaret was proclaimed queen of the Scandinavian kingdoms. She was ultimately succeeded by a grandnephew, Erik of Pomerania. Although Erik came of age in 1401, Margaret continued for the remaining 11 years of her life to be sole ruler in all but name. Her regency marked the beginning of a Dano-Norwegian union which was to last for more than four centuries.

Some Norwegian and Swedish historians have criticized Margaret for favouring Denmark and being too autocratic, although she is generally thought to have been highly regarded in Norway and respected in Denmark and Sweden. She was painted in a negative light in contemporary religious chronicles, as she had no qualms suppressing the Church to promote royal power. Margaret is known in Denmark as Margrethe I to distinguish her from Margrethe II.

Early years and marriage

Margaret was born in March 1353 as the sixth and youngest child of King Valdemar IV and Queen Helvig of Denmark. She was born in the prison of Søborg Castle, where her father had already confined her mother. She was baptised in Roskilde and in 1359, at the age of six, engaged to the 18-year-old King Haakon VI, the youngest son of the Swedish-Norwegian king Magnus IV & VII. As part of the marriage contract, it is presumed that a treaty was signed ensuring Magnus the assistance of King Valdemar in a dispute with his second son, Erik "XII" of Sweden, who in 1356 held dominion over Southern Sweden. Margaret's marriage was thus a part of the Nordic power struggle. There was dissatisfaction with this in some circles, and the political activist Bridget of Sweden described the agreement in a letter to the Pope as "children playing with dolls". The goal of the marriage for King Valdemar was regaining Scania, which since 1332 had been mortgaged to Sweden. Per contemporary sources, the marriage contract contained an agreement to give Helsingborg Castle back to Denmark, but that was not enough for Valdemar, who in June 1359 took a large army across Øresund and soon occupied Scania. The attack was ostensibly to support Magnus against Erik, but in June 1359, Erik died. As a result, the balance of power changed, and all agreements between Magnus and Valdemar were terminated, including the marriage contract between Margaret and Haakon.

This did not result in the withdrawal of Valdemar from Scania; he instead continued his conquests on the island of Gotland in the Baltic Sea. Visby, which was populated by Germans, was the main town on the island and was the key to domination of the Baltic Sea. On 27 July 1361 a battle was fought between a well-equipped Danish army and an array of local Gotland peasants. The Danes won the battle and took Visby, while the Germans did not take part. King Magnus and the Hanseatic League could not disregard this provocation, and a trade embargo against Denmark was immediately enacted, with agreement about necessary military action. At the same time, negotiations opened between King Magnus and Henry of Holstein about a marriage between Haakon and the latter's sister Elizabeth. On 17 December 1362, a ship left with Elizabeth bound for Sweden. A storm, however, diverted her to the Danish island Bornholm, where the archbishop of Lund declared the wedding a violation of church law because Haakon had already been engaged to Margaret. The Swedish and Hanseatic armies also ultimately withdrew from their siege of Helsingborg. Following this, a truce was concluded. The Hanseatic States and King Magnus abandoned the war, and the previous engagement of the now 10-year-old Margaret and King Haakon became relevant again. The wedding was held in Copenhagen on 9 April 1363.

The marriage of Haakon and Margaret was an alliance, and Margaret likely remained in Denmark for some time after the wedding, but ultimately was taken to Akershus in Oslo Fjord where she was raised by Merete Ulvsdatter. Merete Ulvsdatter was a distinguished noblewoman and daughter of Bridget of Sweden, as well as the wife of Knut Algotsson, who was one of King Magnus's faithful followers. Margaret was brought up with Merete's daughter Ingegerd, who likely instructed her in matters of religion and monarchy. Merete's daughters, Ingegerd and Catherine, became her closest female friends, with Margaret later showing favoritism to Ingegerd, who became an abbess, as well as her monastery. It is also likely, though, that her promotion of the Bridgettines was also out of piety and political interest to help the process of integration. Her academic studies were probably limited, but it is assumed that in addition to reading and writing she also was instructed in statecraft. She displayed an early talent for ruling and appears to have held real power.

In the years after Margaret's wedding Scandinavia saw a series of major political upheavals. A few months after her wedding, her only brother, Christopher, Duke of Lolland, died, leaving her father without an obvious male heir. In 1364 the Swedish nobles deposed Margaret's husband and father-in-law from the Swedish throne and elected Albert of Mecklenburg as king of Sweden.
