Blessed Kunegunda (1234-92), also known as St. Kinga (Święta Kinga) was a Princess of Poland, a niece of St. Elizabeth of Hungary and a great niece of St. Hedwig.She married King Boleslaus V of Poland at sixteen, and it was an arranged marriage. During her reign, she got involved in charitable works such as visiting the poor and helping the lepers. She also built churches and hospitals, and ransomed Christians captured by the Turks.
When her husband died in 1279, she sold all her material possessions and gave the money to the poor. She soon did not want any part in governing the kingdom which was left to her and decided to join the Poor Clares monastery at Sandeck. She spent the rest of her life in contemplative prayer and did not allow anyone to refer to her past role as Grand Duchess of Poland. She died on July 24, 1292.
In 1690 Pope Alexander VIII confirmed her cult, the equivalent of beatification. She is one of the Great Saints of Poland depicted above the altar in our church.
