The Duchy of Siewierz was a Silesian duchy with its capital in Siewierz. The area was part of the original Duchy of Silesia established after the death of Duke Bolesław III Wrymouth in 1138 during the times of the fragmentation of Poland.

Siewierz Castle

Siewierz in Upper Silesia was ruled by the Silesian Piasts as part of the Duchy of Bytom under Duke Casimir. In 1312 he granted the town to his youngest son Mieszko, who renounced it in favour of his brother Władysław. In 1337 it was acquired by Casimir I, Duke of Cieszyn, whose scion Wenceslaus I sold it to the Archbishop of Kraków in 1443.

Since 1443, after its acquisition by Archbishop Zbigniew Cardinal Oleśnicki for 6,000 silver groats,^[1] it was, alongside the Duchy of Nysa, the only ecclesiastical duchy in the region (ruled by a bishop of the Catholic Church). On many levels this tiny principality was almost a 'country within a country': it had its own laws, treasury and army.

The junction of the duchy with Lesser Poland was concluded when in 1790 the Great Sejm formally incorporated the Duchy as a Land of the Polish Crown into the Polish–Lithuanian Commonwealth. In the course of the Third Partition of Poland in 1795, the duchy and its adjacent regions were annexed by Prussia and incorporated into the new province of New Silesia. In 1800 the Kraków bishops moved their residence away from Sieiwerz.

Terrirory of the former duchy within Congress Poland

Temporarily recreated in 1807 by Napoleon as a gift for his ally Jean Lannes within the Duchy of Warsaw, after the 1815 Congress of Vienna the lands became part of Congress Poland under Imperial Russian rule. In 1918, Siewierz became part of the Second Polish Republic, from 1939 to 1945 it was occupied by Nazi Germany. The bishops of Kraków continued to use the title of a Prince of Siewierz until the death of Adam Stefan Sapieha in 1951.
