Wikipedia Overview

Sandomierz Voivodeship was a unit of administration and local government in Poland from the 14th century to the partitions of Poland in 1772–1795. It was part of the Lesser Poland region and the Lesser Poland Province. Originally Sandomierz Voivodeship also covered the area around Lublin, but in 1474 its three eastern counties were organized into Lublin Voivodeship. In the 16th century, it had 374 parishes, 100 towns and 2586 villages. The voivodeship was based on the Sandomierz ziemia, which earlier was the Duchy of Sandomierz. The Duchy of Sandomierz was created in 1138 by King Bolesław III Wrymouth, who in his testament divided Poland into five principalities. One of them, with the capital at Sandomierz, was assigned to Krzywousty's son, Henry of Sandomierz. Later on, with southern part of the Seniorate Province, the Duchy of Sandomierz created Lesser Poland, divided into Kraków and Sandomierz Voivodeships.
