Stefan Dušan in the context of "Balsha"

The Serbian Empire (Serbian: Српско царство / Srpsko carstvo, pronounced [sr̩̂pskoː tsâːrstʋo]) was a medieval Serbian state that emerged from the Kingdom of Serbia. It was established in 1346 by Dušan the Mighty, who significantly expanded the state.

During Dušan's rule, Serbia was one of the most powerful European states and the most powerful in Southeast Europe. It was an Eastern Orthodox multi-ethnic and multi-lingual empire that stretched from the Danube in the north to the Gulf of Corinth in the south, with its capital in Skopje. Dušan also promoted the Serbian Archbishopric to the Serbian Patriarchate. In the Serbian Empire, the region of Kosovo was the most prosperous and densely populated area, serving as a key political, religious, and cultural center.

Zeta (Serbian Cyrillic: Зета; Albanian: Zetës; Latin: Zenta or Genta) was one of the medieval polities that existed between 1371 and 1421, whose territory encompassed parts of present-day southern Montenegro and northern Albania, ruled by the House of Balšić.

Zeta was a crown land of the Grand Principality and Kingdom of Serbia, ruled by heirs to the Serbian throne from the Nemanjić dynasty. In the mid-14th century, Zeta was divided into Upper and Lower Zeta, governed by magnates. After Stefan Dušan (r. 1331–55), his son Stefan Uroš V ruled Serbia during the fall of the Serbian Empire, through a gradual disintegration of the Empire as a result of decentralization in which provincial lords gained semi-autonomy and eventually independence. The Balšići wrestled the Zeta region in 1356–1362 when they removed the two rulers in Upper and Lower Zeta. Ruling as lords, they empowered themselves and over the decades became an important player in Balkan politics. Zeta was united into the Serbian Despotate in 1421, after Balša III abdicated and passed the rule to his uncle, Despot Stefan Lazarević (maternally a Nemanjić).

Prizren (Albanian definite form: Prizreni, pronounced [pɾizˈɾɛni]; Serbian Cyrillic: Призрен) is the second most populous city and municipality of Kosovo and seat of the eponymous municipality and district. It is located on the banks of the Prizren River between the foothills of the Sharr Mountains in southern Kosovo. Prizren experiences a continental climate with some mediterranean influences.

Prizren is constitutionally designated as the historical capital of the country. Archaeological excavations in Prizren Fortress indicate that its fortress area has seen habitation and use since the Bronze Age. Prizren has been traditionally identified with the settlement of Theranda in Roman Dardania, although other locations have been suggested in recent research. In late antiquity it was part of the defensive fortification system in western Dardania and the fort was reconstructed in the era of eastern Roman Emperor Justinian. Byzantine rule in the region ended definitively in 1219-20 as the Serbian Nemanjić dynasty took control of the fort and the town. Prizren served as the capital of the Serbian Empire under the reign of Stefan Dušan, as it bloomed to become an important center of trade and commerce during Dušan's reign. From 1371, a series of regional feudal rulers controlled Prizren, including the Mrnjavčević family, the Balšić noble family, the Branković dynasty, as well as the prominent House of Kastrioti. Ottoman Turks captured Prizren from Serbian Despotate in 1455 and almost immediately served as the capital of Sanjak of Prizren in the Ottoman Empire. While standing as an important administrative city for the Ottomans, Prizren became an important political center of the Albanian Renaissance during the late 19th century.

Tsar (/zɑːr, (t)sɑːr/; also spelled czar, tzar, or csar; Bulgarian: цар, romanized: tsar; Russian: царь, romanized: tsar'; Serbian: цар, car) is a title historically used by Slavic monarchs. The term is derived from the Latin word caesar, which was intended to mean emperor in the European medieval sense of the term—a ruler with the same rank as a Roman emperor, holding it by the approval of another emperor or a supreme ecclesiastical official—but was usually considered by Western Europeans to be equivalent to "king".

Tsar and its variants were the official titles in the First Bulgarian Empire (681–1018), Second Bulgarian Empire (1185–1396), the Kingdom of Bulgaria (1908–1946), the Serbian Empire (1346–1371), and the Tsardom of Russia (1547–1721).The first ruler to adopt the title tsar was Simeon I of Bulgaria. Simeon II, the last tsar of Bulgaria, is the last person to have held this title.

The House of Nemanjić (Serbian Cyrillic: Немањић, pl. Немањићи; Serbian Latin: Nemanjić, pl. Nemanjići, pronounced [nɛ̌maɲitɕ]) was the most prominent native Serbian dynasty of Serbia in the Middle Ages. This princely, royal and imperial house produced twelve Serbian monarchs, who ruled between 1166 and 1371.

Its progenitor was Stefan Nemanja, scion of a cadet branch of the Vukanović dynasty (1101–1166). After Nemanja, all monarchs used Stefan as a personal name, or a ruler's name, a tradition adopted for the royal pretensions. The monarchs began as Grand Princes, and with the crowning of Stefan Nemanjić in 1217, the realm was promoted to a Kingdom, and the Serbian Orthodox Church was established in 1219. In 1346, Stefan Dušan was crowned Emperor of the Serbs and Greeks, and the Archbishopric of Serbia was elevated to a Patriarchate.

Saint Stefan Uroš V (Serbian Cyrillic: Стефан Урош V, pronounced [stêfaːn ûroʃ peːti] ; 1336 – 2/4 December 1371), known in historiography and folk tradition as Uroš the Weak (Serbian: Урош Нејаки, romanized: Uroš Nejaki), was the second Emperor (Tsar) of the Serbian Empire (1355–1371), and before that he was Serbian King and co-ruler (since 1346) with his father, Emperor Stefan Dušan.

Between 1345 and 1373, four Serbian monarchs held the title of emperor (tsar). The full title was initially Emperor of the Serbs and Greeks, later Emperor of the Serbs, Greeks and Bulgarians in Serbian and basileus and autokrator of Serbia and Romania ["the land of the Romans"] in Greek. This title was soon enlarged into "Emperor and Autocrat of the Serbs and Greeks, the Bulgarians and Albanians".The Serbian Empire was ruled by two monarchs: Stefan Dušan (r. 1346–1355) and Stefan Uroš V (r. 1355–1371). Two other claimants of the title ruled in Thessaly, Central Greece.
