Sofia of Minsk

Gravestone for Queen Sophia in St. Bendt's Church in Ringsted.

Sophia of Minsk or Sophia of Polotsk (died 5 May 1198) was a Danish queen consort by marriage to King Valdemar I of Denmark, and a landgravine of Thuringia by marriage to Louis III, Landgrave of Thuringia.

Life Origin Sophia was the daughter of Richeza of Poland, Dowager Queen of Sweden, from her second marriage to a man called "Valador", King in Poloni Land. The identity of her father is uncertain, it was either Volodar of Minsk or , Prince of Novgorod and son of Vsevolod of Pskov. Both of them were Rurikids. The latter version would mean Valdemar was married to his first cousin once removed, as Sophia's possible father Volodar was a nephew of Valdemar's mother Ingeborg of Kiev.

Childhood Sophia spent a part of her childhood in Denmark, where her mother had been married to a Danish prince in her first marriage, and returned with her daughter when her second marriage was terminated. Sophia was the half sister of Canute V of Denmark, the son of her mother by her first marriage: after her half brother became king of Denmark in 1146, her mother returned to Denmark with her daughter Sophia, who thus spent part of her childhood in Denmark at the court of her half brother the king.

In circa 1149, her mother married Sverker I of Sweden, in her third marriage. She took her daughter with her to Sweden, where Sophia subsequently spent the rest of her childhood at the Swedish royal court.

Queen In 1154, at the age of circa fourteen, Sophia was betrothed to Valdemar as a symbol of alliance between Sweden and Denmark: she was at this time described as a pretty girl with promise of becoming a beauty. In the marriage contract, she was secured an eighth of her half brother King Canute V's estates in Denmark.

She was widowed in 1182.

Later life As queen dowager, Sophia received a proposal from, and married, Louis III, Landgrave of Thuringia in about 1184, and was escorted to the border by her son and a grand entourage.

She was repudiated in 1190, and returned to Denmark.
