Yolanda of Poland was a 13th-century princess from the Árpád dynasty, born in Esztergom to King Béla IV of Hungary. After being educated in Poland under her sister Kinga, she married Bolesław the Pious in 1257. Throughout her marriage, she became well known for her extensive charitable work, supporting hospitals, monasteries, and the impoverished. Following the death of her husband in 1279, she dedicated her life to religious service, eventually becoming an abbess within the Poor Clare order.
Religious life
After her husband's passing, Yolanda joined her sister and daughter in a monastery in Sandez. Due to regional conflicts, she relocated and established a new community in Gniezno. She served as the abbess of this Poor Clare monastery toward the end of her life. Tradition suggests that she received a divine vision regarding her approaching death before she passed away in 1298.
Veneration
She is recognized as a blessed figure in the Catholic Church. Pope Leo XII beatified her in 1827, and her feast day is observed on June 11. Her sisters, Margaret and Kinga, have also been canonized as saints.
