Delčevo (Macedonian: Делчево [ˈdɛɫtʃɛvɔ] ^ⓘ) is a small town in the eastern mountainous part of North Macedonia. It is the municipal seat of Delčevo Municipality. The town is named after the revolutionary leader Goce Delčev.

Delčevo, according to a legend in Byzantine times, was called Vasilevo, as a Greek variant of the Slavonic Tsarevo. For the first time, Tsarevo Selo is mentioned as a settlement in a charter of Serbian Tsar Dushan from 1347 to 1350. With it he gave several places and fields from Pijanec to the Lesnovo Monastery.

In Turkish times, Delčevo was also called Sultania, by analogy with the original name.

Until the 17th century, the settlement laid on the right side of the river Bregalnica on the present toponym Selishte, more precisely under the hill Ostrec near the road leading to Bulgaria. From the first centuries of Turkish rule there is not much information about the position of Delčevo. In the middle of the 17th century, Sultan Mehmed IV lived in its vicinity. At the time of his visit to Pijanec, mass Islamization was carried out on the population. Due to the oppression and pressure, many Bulgarian settlements were deserted, including the then Tsarevo Selo. It is assumed that at the time of that sultan the settlement was moved to its present place on the left side of the river Bregalnica. The city mosque built in the 17th century is also cited as evidence.

However, it is thought-provoking that the Turkish travel writer Evliya Çelebi spent here only a few years later in 1670 and wrote in his Travelogue:

"From Vinica we climbed the Kocani mountain ore, moving through the gorge and after four hours we reached Tsarevo Selo. This is a Muslim village at the foot of a mountain and is decorated with about 100 houses and a magnificent mosque mined by a minaret."

We should also mention the folk tradition that says that the settlement under the Ostrec hill was deserted when the plague reigned and the surviving population settled on the place where Delčevo is today.

In 1856, the construction of a church was completed. The area around the church was at this time mainly inhabited by Bulgarians fleeing Turkish oppression from the surrounding villages. There was a larger emigration of Bulgarians from the area in 1878 after the Russo-Turkish war. After the end of the war the Christian population, fearing for their safety, fled the region seeking refuge on the territory of the newly created Bulgaria. About 150 households from the villages and the city moved to the Kyustendil region. A small number of those refugees later returned. Turkish refugees from Bulgaria and even Bosnia and Herzegovina settled in the place of the emigrated Bulgarians. The invading Turkish population, called "Madzirci" settled in Madzir maalo (Madzir Neighbourhood), today's III district of the city.
