It was split off the Duchy of Oświęcim, when after eleven years of joint rule the sons of Duke Casimir I in 1445 finally divided the lands among themselves, whereby his eldest son Wenceslaus received the territory around the town of Zator. The fragmentation of the duchy continued after Wenceslaus' death in 1468, when in 1474 his sons Casimir II and Wenceslaus II as well as Jan V and Władysław again divided the Zator territory in two along the Skawa river.

After the death of Casimir II in 1490 however both parts of the duchy were reunited, and in 1494 Jan V as the last surviving brother became its sole ruler. As Jan himself had no heirs, he decided in the same year to sell the duchy to King John I Albert of Poland, under a guarantee that he would remain duke until his death. Jan was killed in 1513 and Zator was united with Poland. At the General sejm of 1564, King Sigismund II Augustus issued privileges of incorporation recognizing both Duchies of Oświęcim and Zator as part of the Polish Crown into the Silesian County of the Kraków Voivodeship, although the Polish kings retained both ducal titles and the name of the Duchy survived in the legal acts (it had however no special privileges).

The lands of the former Duchy became part of the Habsburg Monarchy after the First Partition of Poland in 1772. Though part of Austrian Galicia, Zator and Oświęcim from 1818 to 1866 belonged the German Confederation. Until 1918, the Emperor of Austria also called himself Duke of Zator as a part of his grand title.

When the Second Polish Republic was established in 1918, even the ducal title ceased to exist.

Dukes of ZatorEdit

The Dukes of Zator belonged to the Silesian branch of the Piast dynasty (see also Dukes of Silesia).

Semi-officially from 1494 and officially from 1513 the duchy was part of the Kingdom of Poland.
