called Paetalia (Παιταλία), which he assigns to Thrace, probably a false reading. In the 1st century AD, it was administratively part of Macedonia. Later the city was part of the province of Dacia Mediterranea and the third largest city in the province. The Roman fortress of Pautalia of the 2nd to 4th century had an area of over 29 hectares (appr. 72 acres). The fortress wall was built mainly of granite blocks and unusually its façade was supported with pillars and arches behind. The wall was 2.5m wide allowing small catapults to be mounted atop. A second, smaller fortress of area 2 hectares was built in the town in the 4th century (known by its later Ottoman name Hisarlaka). Many Thracian and Roman objects are exhibited in the town's Regional History Museum, most notably an impressive numismatic collection. Recent excavations have revealed an early Christian, late Roman monumental bishop's palace. Middle Ages The town was mentioned under the Slavic name of Velbazhd (Велбъжд, meaning "camel") in a 1019 charter by the Byzantine Emperor Basil II. It became a major religious and administrative centre of the Byzantine Empire, and subsequently the Second Bulgarian Empire after Kaloyan conquered the area between 1201 and 1203. In 1282, Serbian king Stefan Milutin defeated the Byzantine Empire and conquered Velbazhd. In 1330, the Serbs defeated the Bulgarians in the vicinity, effectively keeping the region to the Serbian Kingdom. Serbian magnate Dejan, one of the prominent figures of the Serbian Empire and its subsequent fall, had initially held a large province in the Kumanovo region under Dušan, and was later as despot under Uroš V assigned the Upper Struma river with Velbuzhd. Upon Dejan's death, his possessions in Žegligovo and Upper Struma were given to his two sons, Jovan Dragaš (d. 1378) and Konstantin (d. 1395). The Dejanović brothers ruled a spacious province in eastern Macedonia, in the southern lands of the Empire, and remained loyal to Uroš V, until 1373, when Orhan Gazi's Ottoman army compelled Jovan to recognize Ottoman vassalage. Ottoman era The city was a sanjak centre initially in Rumelia governorate-general, after that in the Bitola and Niš vilayets (province). It was a kaza centre in the Sofia sanjak of Danube Province until the creation of the Principality of Bulgaria in 1878.
