Constance of Wrocław

Constance of Wrocław (c.1221–27 – 21 or 23 February 1257) was a Princess of Silesia and the Duchess of Kuyavia. She was a member of the Polish House of Piast and mother of Leszek II the Black and Ziemomysł of Kuyavia.

Constance of Wrocław was born in 1227, the second child of Henry II the Pious and his wife Anna of Bohemia, the daughter of Ottokar I of Bohemia and Constance of Hungary. She was named after her maternal grandmother, Constance of Hungary.

Constance and her siblings were brought up away from their parents at the monastery of Trzebnica, where they were cared for by their paternal grandmother Hedwig of Andechs. Hedwig (who was later canonized) greatly influenced the young Constance – she became pious. Later, Hedwig also influenced Constance' son, Leszek.

She was expected to marry soon after coming of age at 12 years, and could do so according to canon law. She married in 1239. At the time only her sister Gertrude was married, to Bolesław I of Masovia. Only one other sister, Elisabeth of Wrocław was to marry, her other sisters becoming Abbesses.

Constance was more carefully educated than her future husband, Casimir I of Kuyavia, who was tutored by John Heron, who was later educated by Casimir's parents.

In 1239 at Wrocław, Constance married Casimir I of Kuyavia, the second son of Konrad I, Duke of Masovia. In literature there are two theories for the marriage.
