The township of Saveh is located to the east of the province. Its climate is moderate to warm. Saveh is the center of this township and is 140 km. from Tehran. Saveh is one of the archaeological cities and ancient regions, i.e., a remnant of the Sassanide period.
In the Parthian era, Saveh was named "Savakineh" and was one of the most important points concerning roads. In the 7th century BC., it was one of the forts and bases in the Medes era. The arrival of Hazrat Ma'soomeh (AS) in Saveh was the first event that has been mentioned in the Islamic history of this city.
The city and region of Saveh was always the winter quarters for Saljuqi and Deylami Monarches. During the Saljuqi period Saveh reached the most flourishing period of its existence, and became the center for the chief of Saljuqi tribes, who were called "Atabak". During the disastrous attack of Mongols in the 7th century AH., Saveh was inflicted with great damages. But in the Ilkhanan era, these were rebuilt.
In Teimoorid and the Qoyonloo era, Saveh was inflicted with great damages because of the looting and rivalry among princes. In the Safavid era Saveh became the settlements for the tribes related to Safavids such as Qezelbashs and Shahsavans, and the city started flourishing. In the Zandieh era, there was an attempt to revive the city commercially, but when Tehran became capital, Saveh lost its importance. In the mid Qajar dynasty era, the habitants of Saveh started to immigrate to Tehran. Presently, Saveh is one of cities of Markazi province.
