As a young girl, Yolanda was sent to Poland to be tutored under the supervision of her sister, Kinga, who was married to the Duke of Poland. There, she was encouraged to marry Bolesław the Pious, which she did in 1257.[3][4]
They had three daughters:
Anna of Kalisz (born 1278, date of death unknown); a nun in Gniezno.
During the time of her marriage, she was noted for her great services to the poor and needy of the country, as well as being a major benefactor of the monasteries, friaries and hospitals connected to them. Her husband gave her so much support in her charities that he earned the nickname "the Pious". She was widowed in 1279.
Following Boleslaus' death, Yolanda and Kinga, along with one of Yolanda's daughters, Anna, retired to the Poor Claremonastery that Kinga had founded in Sandez. Forced to relocate due to armed conflict in the region, Yolanda founded a new monastery in Gniezno.[6] She was persuaded to become abbess of the community of nuns shortly before her death.
