St. Stanislaus was born in 1030 and was educated at Gnesen and at Paris. After his ordination to the priesthood he was made a canon of the cathedral at Cracow as well as archdeacon and preacher. Upon the death of the bishop of Cracow, he was nominated bishop of the diocese by Pope Alexander II.
The king at the time, Boleslaus II, trying to strengthen his own power, led an expedition against the grand duchy of Kiev, making himself very unpopular with the nobles of the country, who opposed his policies. St. Stanislaus of Cracow sided with the nobles, led by the king’s brother, Ladislaus, and this brought him into conflict with the king.
St. Stanislaus had opposed the king before for his tyrannical ways and once confronted him boldly for his immoral behavior when Boleslaus had abducted the wife of a Polish nobleman and carried her off to his castle. No one seemed willing to face the king from a fear of his rage, but Stanislaus boldly went to the king and threatened excommunication if he did not change his ways. Furious, the king promised revenge on the bishop. Later, St. Stanislaus sided with the nobles in their opposition to the king’s political policies, and the king accused him of being a traitor and condemned him to death.
At first the king commanded his soldiers to kill the bishop when he was celebrating Mass at St. Michael’s chapel in Cracow, but the soldiers refused, fearing to bring down upon themselves the wrath of God. Undeterred, the king himself entered the church, drew his sword, and killed the bishop, ordering his soldiers to dismember the body.
Pope Gregory VII placed the country under interdict and Boleslaus fell from power, fleeing to Hungary, where he entered the monastery of Osiak to do penance for his crime. Stanislaus, canonized by Pope Innocent IV in 1253, is one of the patron saints of Poland.
