Jan V of Zator

Jan V of Zator (Polish: Jan V zatorski; before 1455 – 17 September 1513), was a Duke of Zator during 1468–1474 (with his brothers as co-rulers), and ruler over half of Zator from 1474 until his death (during 1474–1482 with his brother as co-ruler).

He was the third son of Duke Wenceslaus I of Zator by his wife Maria, daughter of Urban Kopczowski, a noblemen from the Duchy of Siewierz.

At the time of his father's death in 1468, Jan V and his brother Władysław were likely minors, so their older brothers Casimir II and Wenceslaus II assumed the government over the Duchy. The common government of Wenceslaus I's sons lasted until 1474, when was made the formal division of the Duchy in two parts: Jan V, together with Władysław, received the western part of Skawa River.

In 1477, Jan V and his brothers signed an arrangement of mutual inheritance, who permitted the eventual reunion of the whole Duchy of Zator. Despite this, Jan V entered in conversations with Duke Casimir II of Cieszyn, and also signed with him an inheritance treaty. However, this agreement was null because didn't count with the approval of the Dukes of Zator's sovereign, King Casimir IV of Poland.

By 18 May 1477, Jan V married with Barbara (ca. 1452/53 – bef. 12 May 1507), daughter of Duke Bolesław II of Cieszyn and widow of Duke Balthasar of Żagań. They had no children.

In 1482 Jan V and Władysław made the division of their small Duchy between them. Władysław received a monetary compensation and the town of Wadowice, who was ruled by him until his death in 1494.

The deaths of his brothers Wenceslaus II (1487), Casimir II (1490) and Władysław (1494) allowed Jan V to reunificated the whole Duchy of Zator. However, either him or any of his brothers leave legitimate surviving offspring; for this, on 29 July 1494 Jan V sold his land to the Polish King John I Albert for the amount of 80,000 florins. Since then the formal owner of the Duchy was Poland, but Jan V retain his title and owned several properties in the area, were continue to live. As an additional salary, Jan V received 200 fines per year as an income from the salt mines of Wieliczka.
