Duchy of Jawor
In 1319 it became part of the Piast-ruled Duchy of Jawor, the southwesternmost duchy of fragmented Poland, and Duke Henry I of Jawor confirmed the town's privileges. Later on, the town fell back to Bohemia. From 1346 Görlitz was a wealthy member of the Lusatian League, which consisted of Bautzen, Görlitz, Kamenz, Lubań, Löbau and Zittau. Around 1348 a Jewish woman, Adasse, was made a citizen of the town. In 1352 during the reign of King Casimir III the Great, Lusatian German colonists from Görlitz founded the town of Gorlice in southern Poland near Kraków. In 1469, along with the Lusatian League, the town recognized the rule of King Matthias Corvinus, thus passing to Hungarian rule, and in 1490 it fell back to Bohemia then ruled by Polish prince Vladislaus Jagiellon.
