context_page_description: Henry II the Pious, of the Silesian line of the Piast dynasty, was Duke of Silesia at Wrocław and Duke of Kraków and thus High Duke of Poland as well as Duke of Southern Greater Poland from 1238 until his death. During 1238–1239 he also served as a regent of two other Piast duchies: Sandomierz and Upper Silesian Opole–Racibórz. On October 2015, the Roman Catholic Diocese of Legnica opened up his cause for beatification, obtaining him the title of Servant of God.
context_section_description: Henry the Pious inherited Lower Silesia from his father. Southern Greater Poland and Kraków were ruled by the Piast princes, although the late duke of Greater Poland and Kraków, Władysław III, had left all his lands to Henry the Bearded. The will was ignored by Duke Konrad of Masovia and Władysław's III nephew Władysław Odonic.
  Henry II could retain his authority as a regent over the Upper Silesian Duchy of Opole-Racibórz and the Duchy of Sandomierz during the minority of their rulers Mieszko II the Fat and Bolesław V the Chaste. Nevertheless, in 1239, Henry was compelled to resign the regency, although he remained on good terms with the Dukes of Opole and Sandomierz, and managed to retain Greater Polish Kalisz and Wieluń.
  The situation in the northwest was more complicated: Margrave Otto III of Brandenburg took the important Greater Polish fortress at Santok and besieged Lubusz. Henry II also inherited the disputes with Konrad of Masovia, Władysław Odonic, and with the Church, led by Pełka, Archbishop of Gniezno. The situation changed unexpectedly after the death of Władysław Odonic on 5 June 1239, who left two minor sons, Przemysł I and Bolesław the Pious. Henry II took the majority of Odonic's possessions (including Gniezno), leaving Nakło nad Notecią and Ujście to Odonic's sons.
  Henry then abandoned the traditional alliance of his family with the Imperial House of Hohenstaufen and supported Pope Gregory IX, immediately resolving his dispute with the Church. He then put an end to his conflicts with Konrad of Masovia by arranging the marriages of two of his daughters to two of Konrad's sons: Gertrude to Bolesław, and Constance, to Casimir I of Kuyavia. In 1239, Henry II reclaimed the Santok fortress from Margrave Otto III after Henry's victory in the Battle of Lubusz.
