Savojbolagh County (Persian: شهرستان ساوجبلاغ) is in Alborz province, Iran. Its capital is the city of Hashtgerd.[3]
History
The name Savojbolagh[a] is derived from Turkish and means "cold springs."[4] The 14th-century author Hamdallah Mustawfi described it as having "a fine climate"; most of its water was drawn from qanats, and it produced a lot of fruit and grain.[5] He wrote that the district had previously been attached to Ray for fiscal purposes under the Seljuk Empire, but under Mongol rule it had been detached.[5] Its inhabitants, he wrote, were nomads who were "indifferent to religious matters".[5] The main villages were Sonqorabad, Najmabad, and Kharav.[5] The district's tax revenues he listed as 12,000 dinars.[5]
In 2007, two villages merged to form the new city of Seyfabad,[6] later renamed Golsar.[7] In 2010, the county was separated from Tehran province in the establishment of Alborz province.[3]
At the time of the 2006 census, the county's population (as a part of Tehran province) was 215,086 in 57,497 households.[11] The 2016 census measured the population of the county as 259,973 in 80,953 households.[2]
