She was 1248 married to prince Christopher, the youngest son of Valdemar II of Denmark and Berengaria of Portugal. Her husband ascended the throne of Denmark in 1252 as Christopher I of Denmark by the then succession custom which followed so called agnatic seniority and Margaret was crowned together. Christopher I (1219-May 29, 1259) was king of Denmark between 1252 and 1259. ... In hereditary monarchies, particularly in more ancient or in more underdeveloped times, seniority was a much used principle of order of succession. ...

Her husband died 29 May 1259 (rumoredly poisoned). Their son and heir Eric V of Denmark who succeeded was a minor and Margaret was made regent, in which position she continued until 1264. Eric's succession overrode rights of sons of earlier monarchs and was against the traditions of agnatic seniority. However, only such living were sons of king Abel, who had the fame of fratricide, murderer, and it was easier to dispossess them. King Christopher had all his reign made work to ensure his own line's succession. Although the accession of Eric led to serious rivalry for generations, Christopher's line was usually victorious and kept the kingship. Eric V Klipping (1249-1286) was King of Denmark (1259-1286) and son of Christopher I. Until 1264 he ruled under the auspices of his mother, the competent Queen Dowager Margrethe Sambiria. ...

She quarreled with lord Jakob Erlendsen and her husband's nephew Eric Abelson, as well as with counts of Holstein. After a loss in Lohede 1261 she together with her son the young king became imprisoned by Holsteins, but soon succeeded to liberty with help from Duke Albert of Brunswick. She took initiative. Margaret has a reputation of a very competent regent. Her nicknames "Spränghäst" and "Svarta Grete" are based on her strong will and energy. She died in december 1282. And is buried at Cistercian church in Doberan in northern Germany.

Margaret and Christopher had three children:

• Matilda (died 1311), married to Albert III, margrave of Brandenburg
• Margaret (died 1306), married count John II of Holstein-Kiel
• Eric, the future king of Denmark (1249-1286).

A never-ending rivalry between Eric and his supporters on one side, and the kin of former King Abel on the other, made Queen Margrethe write to the Pope in Rome around 1262 or 1263, asking the Pope to allow for women to inherit the Danish throne, thus making it possible for one of Eric's sisters to become reigning Queen of Denmark in the event of the young King's death (he had no children as of yet).
