Đorđe Nemanjić or George of Zeta (; fl. 1208–1243) was the Grand Prince of Zeta, from at least 1208 until at least 1243. For some time, he also was a self-styled King of Duklja. He was the son of rival Serbian Grand Prince and titular King Vukan Nemanjić (r. Serbia 1202–1204, Duklja (Zeta) 1190–1208), hence George too was a titular King, for a few years after his father's death. He continued the struggle between his father and uncle, and accepted the suzerainty of the Republic of Venice. Background Stefan Nemanja had managed to secure the independence from the Byzantine Empire after the death of emperor Manuel I (1180), and then conquered the traditional fiefs of Duklja, Travunia and Hum on the Adriatic coast. Nemanja gives Vukan, as heir presumptive, appanages of the conquered lands, including Hvosno and Toplica around 1190 as Grand Prince. Although Vukan was the eldest son of Stefan Nemanja, Nemanja had instead chosen his younger son Stefan [II] as heir. This was done as Nemanja preferred to see Stefan Nemanjić on the Serbian throne as he was married to Eudokia, the daughter of Byzantine Emperor Alexios III Angelos. It seems that Vukan reacted on this change in succession by adopting a royal title; in an inscription dated 1195 in the church of St. Luke in Kotor, Vukan is titled as King of Duklja, Dalmatia, Travunia, Toplica and Hvosno. Although Vukan assumed a royal title, he remained under his father's authority. In 1196, at a State Council, Nemanja abdicated in favour of Stefan; Vukan had to recognize his brother as the new ruler of Serbia. Nemanja took monastic vows and was given the name Simeon, and retreated to Hilandar at Mount Athos. While Nemanja was alive Vukan didn't oppose Stefan's rule but as soon as Nemanja died in 1200 he started to plot against Stefan in order to become Grand Prince. He found aid in Hungarian King Emeric (1196–1204) who at the time fought against the Second Bulgarian Empire and wanted Serbian assistance. With the help of Hungarian troops in 1202, Vukan managed to overthrow Stefan, who fled to Bulgaria, and Vukan was left to rule. In an inscription dating to 1202–1203, Vukan is titled as Grand Župan Vukan, Ruler of all Serbian land, Zeta, maritime towns and land of Nišava. In return for Hungarian help, Vukan became a Hungarian vassal and promised that he would convert to
