Early life Martha, the daughter of King
Eric V of Denmark and
Agnes of Brandenburg and the sister of King
Eric VI, was born sometime between 1277 and 1282. Her elder brother
Christopher was born in 1277, and by 1282, peaceful relations had been restored between Denmark and Sweden, leading to agreement that Princess Martha would marry Prince
Birger, the heir to the Swedish throne. According to
Petrus Olai, this agreement was made as early as 1280. The
papal dispensation for the marriage, necessary due to the previous family ties, was obtained in 1284. In 1304, Queen Martha as well as her sister-in-law Queen Ingeborg attended the border meeting between King Birger and her brother King Eric at Knäred or Fagerdala.
Exile In Denmark, Birger and Martha were accompanied by their daughters Agnes and Katarina. On 4 September 1318, King Eric of Denmark granted Martha the manor of Hjarup in
Jutland for her income. The following year, her brother Eric died and was succeeded by her younger brother
Christopher II of Denmark, with whom she was reportedly not on as good terms as with her elder brother, possibly because Christopher had earlier sided with Birger's brothers against Eric. ==Issue==
