Early Konstantin's father was the
despot and
sevastokrator Dejan, who had held the
Kumanovo-region under the rule of
Stefan Dušan (r. 1331–1355). Konstantin's mother
Teodora Nemanjić was a half-sister of Dušan. His maternal grandparents were King
Stefan Dečanski (r. 1321–1331) and
Queen Maria Palaiologina.
Reign In around 1365, Dejanović's older brother
Jovan Dragaš was holding
Štip and
Strumica. Jovan was elevated to
despot by Emperor
Uroš V (before 1373), as Emperor Dušan had elevated Dejan, their father. Ottoman sources report that in 1373, the Ottoman army compelled "Saruyar" (Jovan Dragaš) in the upper Struma, to recognize Ottoman vassalship. Konstantin had helped Jovan in ruling the lands, and when Jovan died in 1378/1379, Konstantin succeeded, subsequently managing to govern large portions of northeastern
Macedonia and the
Struma valley. He minted coins, as had his brother done. The
Dragaš family generously donated to several monasteries on
Mount Athos, including
Hilandar,
Pantaleimon (Rossikon) and
Vatopédi. On 10 February 1392 Dejanović's daughter
Jelena married
Manuel II Palaiologos. The next day, they were crowned Emperor and Empress by the patriarch. After the
battle of Maritsa, they were forced to become vassals of the
Ottoman Empire, but they maintained close links with their Christian neighbors, including the
Byzantine Empire. In 1395, together with his neighbor and ally, the Serbian king of
Prilep Marko, Konstantin Dragaš was killed fighting for their Ottoman overlord Sultan
Bayezid I against
Mircea cel Bătrân of Wallachia at Rovine, near
Craiova. The Ottomans named Konstantin's capital Velbužd after him,
Köstendil (now Bulgarian
Kyustendil). ==Family==
