edict in the Republic of Ragusa that confirmed the laws of Emperor Stefan Uroš V and gave privileges to Ragusan traders, including imposed taxes. It also included a unique clause, recognizing the sovereignty and territorial integrity of the Serbian Empire despite being without an Emperor for years and any form of strong centralized authority, a note that if anyone would become the new sovereign Emperor of the Serbs and the Serbian nobility and lands (), all the points shall be transferred from the Balšićs to him. Đurađ I's logotet Vitko was the witness, as well as Dragaš Kosačić. In 1375, Lazar Hrebeljanović and Đurađ convened the state assembly (sabor) during which Jefrem was chosen as Serbian Patriarch. After the Battle of Maritsa, Marko, the son of Vukašin Mrnjavčević, was crowned king and gained his father's lands. However, his friendship with the Balšićs soon crumbled. This was a result of Đurađ, in 1371, expelling his first wife Olivera, Marko's sister, and took Prizren from Marko. Lazar Hrebeljanović, prince of Moravian Serbia, conquered Priština in the same year. Đurađ took Peć a year later, stripping most of Marko's lands north of Šar mountain. Đurađ I died on 13 January 1378 in Skadar. However, recent studies now conclude that Đurađ died in 1379 rather than in 1378. The rule of Zeta was passed down to his younger brother, Balša II. Đurađ's death caused quite a stir between Zeta's neighbours. Bosnian Ban Tvrtko I annexed Đurađ's territories bordering Dubrovnik in 1377, along with the remainder of Đurađ's coastal lands between the Bay of Kotor and the land previously annexed in 1377 at the time of his death. Tvrtko secured these possessions through Đurađ's death, free of worry of any counter-attack. Vuk Branković also took this opportunity to gain Đurađ's land. Branković sent his forces into Metohija and seized Prizren, along with the rest of Đurađ's holdings in the region. Titles gospodin (господин, "lord").
