"-In God Christ beloved Stephen, emperor to all Serbs and Greeks, and to the Bulgarian countries, and to the whole West, Pomerania, Frugia and Arbanasi-
Stefan Uroš IV Dušan known as Dušan the Mighty (26 July 1308 – 20 December 1355), was the King of Serbia from 8 September 1331 and Tsar (or Emperor) and autocrat of the Serbs and Greeks (or Romans) from 16 April 1346 until his death. Dušan conquered a large part of southeast Europe, becoming one of the most powerful monarchs of the era. Under Dušan's rule, Serbia was the major power in the Balkans, and an Eastern Orthodox multi-ethnic and multi-lingual empire that stretched from the Danube in the north to the Gulf of Corynth in the south, with its capital in Skopje. He enacted the constitution of the Serbian Empire, known as Dušan's Code, perhaps the most important literary work of medieval Serbia.
Dušan promoted the Serbian Church from an archbishopric to a Patriarchate, finished the construction of the Visoki Dečani monastery, and founded the Saint Archangels Monastery, among others. Under his rule Serbia reached its territorial, political, economic, and cultural peak.
Dušan died in 1355, seen as the end of resistance against the advancing Ottoman Empire and the subsequent fall of the Eastern Orthodox Church in the region."
