Shahin Dezh () is a city in the Central District of Shahin Dezh County, West Azerbaijan province, Iran, serving as capital of both the county and the district.
Shahin Dezh is about 1,300 meters in elevation. The city is on the Zarrineh River, southeast of Lake Urmia.
The modern town of Shahin Dezh was formerly known as á¹¢ÃÂþën QalâÂÂeh. The name á¹¢ÃÂþën (also spelled SÃÂën, Shahin, etcetera.) is derived from the Mongol sayin, which translates as "good".
The local Turkic Afshars were brought to the area from Shiraz at the beginning of the 19th century by Fath-Ali Shah Qajar (1797âÂÂ1834), the second Qajar shah ("king") of Iran. Later, a segment of these Afshars had to migrate to Urmia in order to make way for the Chardawri (Chardowli) Lurs. The chief of the Chardowli's resided at Mahmuddjik and was the commander of men. In 1830, á¹¢ÃÂþën QalâÂÂeh was sacked by Kurds led by Sheikh Ubeydullah. á¹¢ÃÂþën QalâÂÂeh, being the site of an Iranian military garrison in the past, safeguarded the entrance to the Azerbaijan Province through the Zarrineh valley.
The ancient Karaftu Caves, first described by Robert Ker Porter (1777âÂÂ1842), and the old site of Takht-e Soleyman were formerly located in the territory of the Afshars of á¹¢ÃÂþën QalâÂÂeh. The lake of Chamli Göl, near the village of Badarli with its floating island were likewise well known at the time. Some of the Afshars of á¹¢ÃÂþën QalâÂÂeh belonged to the Yarsanism sect.
The old site of á¹¢ÃÂþën QalâÂÂeh is now occupied by the modern town of Shahin Dezh, which is also the chef-lieu of Shahin Dezh County. In , its population was 3,170 which by 1991 had increased to 25,050.
The fortress of á¹¢ÃÂþën QalâÂÂeh is sometimes confused with the similarly named fortress on the Abhar river to the east of Soltaniyeh, which was mentioned by Hamdallah Mustawfi (1281 â after 1339/40).
At the time of the 2006 National Census, the city's population was 34,204 in 8,671 households. The following census in 2011 counted 38,396 people in 10,782 households. The 2016 census measured the population of the city as 43,131 people in 12,826 households.
