Incompetent to sustain the great empire created by his father, Uroš could neither repel attacks of foreign enemies, nor combat the self-will of his nobility. This situation was exploited by the Byzantine Empire which took from him Serbian Greece, and Hungary which took hold of Mačva and Belgrade. In his own state in 1358 he faced rebellions firstly from his uncle, the despot of Epirus Simeon, and his mother Jelena, who started to rule autonomously with their areas. Following their example, Dejankovićs; Vukašin and Uglješa Mrnjavčević; brothers Balšić; and Nikola Altomanović also rose against him. At the end of his rule the only lands under direct Uroš's control were those between the Šara and the Danube.

In 1345 the Serbian King StefanUros IV Dusan proclaimed himself emperor and had himself crowned as such at Skopje on Easter 1346 by the newly created Patriarch of Serbia, and by the Patriarch of Bulgaria and the autocephalous Archbishop of Ohrid.
It was only employed by StefanUros IV Dusan and his son StefanUrosV in Serbia, after which it became extinct.
A half-brother of Dusan, Simeon Uros, and then his son Jovan Uroš, claimed the same title, until the latter's abdication in 1373, while ruling as dynasts in Thessaly.
StefanUrošV Nejaki ("The Weak"), (Serbian: Стефан Урош V нејаки) (1336–1371) was king of Serbia (1346–1355) as co-ruler of his father StefanUroš IV Dušan and then emperor (tsar) (1355-1371).
StefanUrošV was the only son of StefanUroš IV Dušan by Helena of Bulgaria, the sister of Ivan Alexander of Bulgaria.
StefanUrošV died childless in December 1371, after much of the Serbian nobility had been destroyed by the Turks in the Battle of Marica earlier that year.
