Saint Kinga of Poland (also known as Cunegunda, Kunigunda, Kunegunda, Cunegundes, Kioga, Zinga; Polish: Święta Kinga, Hungarian: Szent Kinga) (March 5, 1224 – July 24, 1292) is a saint in the Roman Catholic Church and patroness of Poland and Lithuania. She was the daughter of King Béla IV of Hungary and Maria Laskarina. She was a niece of St. Elizabeth of Hungary and great-niece of Saint Hedwig. Kinga’s sisters were Saint Margaret of Hungary and Jolenta of Poland (Yolanda, Helen). She reluctantly married Bolesław V the Chaste. Kinga later became princess when her husband ascended the throne as Prince of Cracov. Despite the marriage, the devout couple took up a vow of chastity. The marriage was largely arranged by and the vow of chastity pattered after that of Boleslaw’s sister Salome of Cracow. During her reign Kinga got involved in charitable works such as visiting the poor and helping the lepers. 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 would spend 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. Pope Alexander VIII beatified Kinga in 1690. In 1695 she was made chief patroness of Poland and Lithuania. On June 16, 1999 she was canonized by Pope John Paul II.
