Arasbaran (ارسباران Arasbârân, 'banks of the Aras'), also known as Qaradagh (Qaradağ, قرهداغ, 'black mountain'), is a large mountainous area stretching from the Qūshā Dāgh massif, south of Ahar, to the Aras River in East Azerbaijan Province of Iran. The region is confined to Aras River in the north, Meshgin Shahr County and Moghan in the east, Sarab County in the south, and Tabriz and Marand counties in the west. Since 1976, UNESCO has registered 72,460 hectares of the region, confined to 38°40' to 39°08'N and 46°39' to 47°02'E, as biosphere reserve with the following general description: blockquote|This biosphere reserve situated in the north of Iran at the border to Armenia and Azerbaijan belongs to the Caucasus Iranian Highlands. In-between the Caspian, Caucasus and Mediterranean region, the area covers mountains up to 2,200 metres, high alpine meadows, semi-arid steppes, rangelands and forests, rivers and springs. Arasbaran is the territory of about 23,500 nomads who are mainly living in the buffer and transition zones (2000). Economic activities in the biosphere reserve are mainly agriculture, animal husbandry, horticulture, apiculture, handicrafts and tourism, but business activities can also be found in urbanized areas. In antiquity, this region was inhabited by the Alarodians and Caspian tribes. Then this area became alternately part of the Medes and Persia. In the 2nd century B.C. the region became part of the Armenian kingdom, where the Armenian principality Parspatunik was established, which existed until the 6th century A.D. Small Armenian melikdoms of Karadagh (Arasbaran) remained until the Turkish invasion of 1918. The Armenian population is preserved in the mountains of Arasbaran(Karadagh) in modern day. There is no mention of Arasbaran as a geo-political entity in written sources dating prior to Safavid era. There is a speculation that the region referred to as Syah Kuh by the 10th-century Muslim geographer, Ibn Hawqal, corresponds to the present day Arasbaran.
