Emperor of the Serbs

Between 1345 and 1371, the Serbian monarch was self-titled 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 only 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.
