Naqadeh, also known as "Nexede", Naghadeh, Naghdeh and Nagadeh (formerly known as "Sindus" (in Kurdish) and "Sulduz" (in Azeri); also Romanized as Sulduz, Solduz and Suldoz), is a city in and the capital of Naqadeh County, West Azerbaijan Province, Iran. At the 1996 census, its population was 110,257, in 20,781 families.
The city is located in the Gadar River valley, 23 kilometres (14 mi) south of Lake Urmia at an elevation of 1,300 metres (4,300 ft) above sea-level. The region's economy is based on agriculture, particularly the production of fruit, grain, and timber.
The town is inhabited mainly by Iranian Azerbaijanis and Qarapapaqs, the latter of whom were resettled from the Caucasus into the newly established borders of Persia/Iran after the loss of Georgia, Azerbaijan, Dagestan, and Armenia to neighboring Russia following the first and second Russo-Persian Wars of the (19th century). The main religion of the area is Shia Islam, as with most of Iran. 
The regional economy greatly depends on agricultural products, and cattle and sheep are raised both for meat and for wool. Some of this production is exported. The region's farmers also raise apples, grapes, tomatoes, potatoes, onions, peas, and other fruits. The high farm production results from the fertile soil and the use of modern machinery and scientific farming methods.
