Emperor Stefan Uroš IV Dušan was succeeded by his son
Stefan Uroš V whose reign was characterized by decline of central power and rise of numerous virtually independent principalities. Stefan Uroš V was not able to sustain the great empire created by his father, or limit the independence of the powerful nobles.
Vukašin Mrnjavčević was the most powerful noble in the Serbian Empire, ruling northern Macedonia. Although he was given the title of Despot by Emperor Uroš in 1355, his steady power increase enabled him to crown himself King of Serbs and Greeks in 1365, and extend his claims over west and south Macedonia, Kosovo, and Raška.
Preparations Since the Mrnjavčević family desired to succeed the
Nemanjić dynasty as the new rulers of Serbia, Emperor Uroš started supporting a coalition of Serbian elite loyal to him. One of them was
Lazar Hrebeljanović, who was married to
Princess Milica from the Nemanjić family. Lazar and the Emperor managed to persuade the young but capable general
Nikola Altomanović to join their coalition, as well as some minor governors. But, since Nikola was at war with
Bosnia, he was only able to bring a portion part of his army, because he had to keep large part of his army on his lands, to protect them from the possible Bosnian attack. Vukašin on the other hand, had the largest and the most powerful army in the Empire - which was also fully professional. ==Battle==
