Kyustendil Province (Bulgarian: Област Кюстендил, romanized: Oblast Kyustendil) is a province in southwestern Bulgaria, extending over an area of 3,084.3 km (1,190.9 sq mi) (constituting 2.7% of the total territory of the Republic of Bulgaria), and with a population of 106 131. It borders the provinces of Sofia, Pernik, and Blagoevgrad; to the west, its limits coincide with the state borders between Bulgaria and North Macedonia, and between Bulgaria and the Republic of Serbia. The administrative center of the Province is Kyustendil.

Dejan (Serbian Cyrillic: Дејан; fl. 1346 – c. 1366) was a magnate who served Serbian Emperor Stefan Dušan (r. 1331–55) as sevastokrator, and Emperor Uroš V (r. 1355–71) as despot. He was married to Emperor Dušan's sister Teodora, and possessed a large province in the Kumanovo region, east of Skopska Crna Gora. It initially included the old župe (counties) of Žegligovo and Preševo (modern Kumanovo region with Sredorek, Kozjačija and the larger part of Pčinja). Uroš V later gave Dejan the Upper Struma river with Velbužd (Kyustendil). Dejan rebuilt the Zemen Monastery, one of Dejan's endowments, among others, as he also reconstructed several church buildings throughout his province.

Dejan was one of the prominent figures of Dušan's reign and during the fall of the Serbian Empire after Dušan's death. Dejan is the progenitor of the Dejanović noble family, with his two sons, despot Jovan and gospodin Konstantin, also becoming powerful during the fall of the Serbian Empire and the ensuing Ottoman period.

The Battle of Velbazhd (Bulgarian: битка при Велбъжд, romanized: bitka pri Velbazhd; Serbian: Битка код Велбужда, romanized: Bitka kod Velbužda) was fought by the Bulgarian Empire and the Kingdom of Serbia on 28 July 1330, near the town of Velbazhd (present day Kyustendil).

The growing power of the Serbian Kingdom from the late 13th century raised serious concerns in the traditional Balkan powers Bulgaria and Byzantine Empire which agreed for joint military actions against Serbia in 1327. Three years later the bulk of the Bulgarian and Serbian armies clashed at Velbazhd and the Bulgarians were caught by surprise. Serbian victory shaped the balance of power in Balkans for the next two decades. The Bulgarians did not lose territory after the battle but were unable to stop the Serbian advance towards Macedonia. Serbia managed to conquer Macedonia and parts of Thessaly and Epirus reaching its greatest territorial extent ever. Their new king Stefan Dušan was crowned Emperor with support from Bulgarian Patriarch Symeon in 1346.
