Jan V of Zator

Jan V of Zator (; before 1455 – 17 September 1513), was a Duke of Zator during 1468–1474 (with his three brothers as co-rulers), ruler over the western half of Zator from 1474 to 1494 (with his brother Władysław as his co-ruler), and ruler of a reunified duchy from 1494 to his death. 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. Life 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.
