Sophie of Landsberg

Sophie of Landsberg (Polish: Sophie z Landsberg, German: Sophie von Landsberg) (ca. 1259 – 24 August 1318) was a German princess member of the House of Wettin and by marriage Duchess of Glogów.

She was the eldest child and eldest daughter of Dietrich the Wise, Margrave of Landsberg, by his wife Helena, daughter of John I, Margrave of Brandenburg.

On 24 October 1266 was issued in Augsburg by Duke Louis II of Upper Bavaria a settlement, under which he pledged several possessions on behalf of his ward and nephew Conradin, King of Sicily and Jerusalem. This action was made in order to pay the expenses incurred in connection of the marriage celebrated between Conradin and Sophie, who took place by the end of October and early September of that year, possibly in the city of Bamberg or Nürnberg. The union was celebrated by proxy (desponsatio per procuratinem), because the fourteen-years-old King was absent at that moment. In his place, Duke Louis II stood as groom and signed the marriage contract.

Conradin never seen his bride: soon after the marriage, he departed with his friend Frederick I of Baden to Italy with the purpose to recover his rights over Frederick II's inheritance, and two years later, on 29 October 1268, the last legitimate male member of the House of Hohenstaufen was beheaded in the Piazza del Mercato of Naples.
