The Nochiya Region, which is different from Nochiya (a sub-district located in the Nochiya Region), is the area which consists of five districts and many sub-districts. The Nochiya Region lies in three countries: western Iran, northeastern Iraq and southeast Turkey. The districts that make up parts of the Nochiya Region are Shamizdin, north eastern half of the Shaqlawa District, Soran District, Mergasur District and the western part of Urmia District.
Nochiya itself was actually the central sub-district; to the north of it in Turkey were the Khumara and Dairaneh Clans. To the east, in Persia were the Targawar, Bagzadeh and Margawar sub-districts. To the south, in what is now mostly Iraq, were the Gargan, Bradost, Sherwan and Rawandiz Districts. The sub-district of Nochiya is a historical area that lies in the heart of Shamizdin (modern day Şemdinli).
The Semdinli district to which Nochiya (Rustaqa) belongs, was named after the great Sheikh Shams Al Din Abbasi who was the religious chief, around ~1100, of the kurdish Bagzadeh Tribe in Targawar (Urmia, Iran), Kurdish abbasi tribes in Hakkari, Khumaru, Badinan as well as Kilise north av Alepo. Targawar, Dasht and Margawar before the border were set in 1514 were actually part of Shamizdin. Prior to that, it was known as Bet Bgash with its capital village being Biyyeh, in the Sherwan district of Barzan, Iraq.
