Saint Stefan Uroš V of Serbia

Saint Stefan Uroš V , 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. Stefan Uroš V was the only son of Stefan Uroš IV Dušan by Helena of Bulgaria, the sister of Ivan Alexander of Bulgaria. He had been crowned as king (second highest title) in the capacity of heir and co-ruler after Dušan was crowned emperor in 1346. Although by the time of his succession as sole ruler and emperor in 1355 Stefan Uroš V was no longer a minor, he remained heavily dependent on his mother and various members of the court. The account of the contemporary John VI Kantakouzenos describes the descent of the Serbian Empire into disintegration soon after the death of Uroš' father and his accession. However, Kantakouzenos mainly focused on the Greek lands rather than the Serbian core lands. Further the general disorder along with the powerlessness of the center represents the situation that arose much later in Uroš's reign. According to Mihaljčić, during the initial years of his rule the threats to the territorial integrity of Uroš's empire in the south came mainly from external attacks. The death of Uroš's father was quickly followed by the death of Preljub, who governed the region of Thessaly. In the spring of 1356, Nikephoros Orsini landed a force on the coast of Thessaly and quickly overran it. He then followed up this success by driving despot Simeon Uroš from Aetolia and Acarnania. Simeon was a paternal uncle and the closest male relative of young Emperor Uroš. Retreating to Epirus and western Macedonia, he seized Kostur and proclaimed himself Tsar in hope of becoming co-ruler, or even replacing young Uroš on the Serbian throne. His claim was not widely welcomed, and the support he gained was limited to some southern regions.
