History
Pre-Islamic Period: The upper Tigris valley where Kozluk is located hosted settlements in the Neolithic, Chalcolithic, and Bronze Ages. Excavations at the Hallan Çemi mound in Kaletepe village in 1990 uncovered female ornaments, animal figures, and stone weapons dating back approximately 12,000 years. These findings showed that the region was an older settlement than Çayönü. Civilizations such as Subarians, Hurrians, Sumerians, Akkadians, Assyrians, Babylonians, Urartians, Medes, Persians, Macedonians, Seleucids, Sasanids, Romans, and Byzantines lived in Kozluk. Around 1000 BC, the Assyrians fought with the Kur-tie tribe in the Hazo mountains; Ashurbanipal captured the Nişton fortress.
Pre-Ottoman Islamic Period: Kozluk was conquered by Iyad b. Ghanem during the period of Hz. Omar (H. 18/639) and incorporated into Islamic lands. It was ruled by the Umayyads, Abbasids, Hamdanids, Marwanids, Seljuks, Dilmaçoğulları, Artuqids, Ayyubids, Kara Koyunlu, Ak Koyunlu, and Safavids. During the Seljuk period (after 1085), the Hazo-Sason castles came under Seljuk rule. The Ayyubids established dominance in the region in the 13th century, and the Ak Koyunlu in the 15th century. Under pressure from the Safavids, the Ottomans took control of the region in 1515-1516 through the efforts of Idris-i Bitlisi.
Ottoman Period: Kozluk was administered as the principality of Sason-Hazo during the Ottoman period. According to Şerefname, the origin of the principality lies with the brothers İzzeddin and Ziyaeddin. In the 16th century, it was a sanjak (sub-province) of the Diyarbekir eyalet, sometimes administered with the status of a government. Evliya Çelebi described Hazo in 1655 as a small fortress and town. Hazo, a district of Siirt sanjak in the 19th century, had a population of 10,000 in the 1890s. According to Vital Cuinet, half of the population was Muslim, and the other half consisted of Armenian Gregorians and Catholics.
Republican Period: Hazo, which was a sub-district of Muş in the early years of the Republic and then of Sason, gained district status under Siirt in 1938 and was named Kozluk. It was connected to Batman when it became a province in 1990. Tobacco farming and leaf-tobacco enterprises led to population growth, but migration to large cities occurred due to tobacco quotas and security issues. With infrastructure investments, the district has become suitable for economic development.
