Constance, Duchess of Wodzisław

Constance (Polish: Konstancja; died 1351) was a Polish princess from the House of Piast and sovereign Duchess of Wodzisław Śląski from 1324 until her death. Her name appears twice in contemporary sources: firstly, in a letter of Pope John XXII dated 22 September 1321, where she is named "Duchess of Racibórz", and secondly in the Chronicle of Racibórz, who give her the title of "Duchess of Wodzisław" (księżną wodzisławską) and mentions her death in 1351.
