Casimir II the Just was a Lesser Polish Duke at Wislica during 1166–1173, and at Sandomierz after 1173. He became ruler over the Polish Seniorate Province at Kraków and thereby High Duke of Poland in 1177; a position he held until his death, interrupted once by his elder brother and predecessor Mieszko III the Old. In 1186 Casimir also inherited the Duchy of Masovia from his nephew Leszek, becoming the progenitor of the Masovian branch of the royal Piast dynasty, great-grandfather of the later Polish king Wadysaw I. The honorific title "the Just" wasn't contemporary; it only appeared in the 16th century.
Casimir, the sixth but fourth surviving son of Bolesaw III Wrymouth, Duke of Poland, by his second wife Salomea, daughter of Count Henry of Berg, was born in 1138, probably on the brink of his father's death. It is however also possible that he was born shortly after, and in consequence was posthumous. Maybe this was the reason that in the Bolesaw III's Testament, he was omitted and left without any land.
During his reign, Casimir was very generous to the Church, especially with the Cistercians monasteries of Wachocku, Jedrzejow, Koprzywnicy and Sulejów; with the Order of the Holy Sepulchre of Miechów and Regular Canonry of Czerwin'sk nad Wisa; and Trzemeszno and the Order of the Knights Hospitaller in Zagosc. He also tried to expand the cult of Saint Floriana, whose remains were brought to Kraków by Bishop Gedko.
Around 1163, Casimir married with Helen (ca. 1140/42 – ca. 1202/06), daughter of Duke Conrad II of Znojmo, scion of a Moravian cadet branch of the Premyslid dynasty. They had seven children:
Maria (1164–1194), married in November 1178 to Prince Vsevolod IV of Kiev.
Casimir (ca. 1165? – 1 March 1167).
Bolesaw (ca. 1168/71 – 16 April 1182). He died accidentally, after falling from a tree.
Odon, died in infancy.
Adelaide (ca. 1177/84 – 8 December 1211), foundress of the convent of St. Jakob in Sandomierz.
Leszek I the White (ca. 1186/87 – Marcinkow, 23 November 1227).
Konrad (ca. 1187/88 – 31 August 1247).
