Introduction and history
Qazvin was the location of a former capital of the Persian Empire and contains over 2000 architectural and archeological sites. It is a provincial capital today that has been a cultural center of mass throughout history.
Archeological findings in the Qazvin plain reveal the existence of urban agricultural settlements as far back as 7000BC. The name “Qazvin” or “Kasbin” is derived from Cas, an ancient tribe that lived south of the Caspian Sea millennia ago. Qazvin is historically also rendered as Kazvin, Kasvin, and Casbin in western texts. The Caspian Sea itself in fact derives its name from the same origin. Qazvin geographically connects Tehran, Isfahan, and the Persian Gulf to the Caspian seacoast and Asia Minor, hence its strategic location throughout the ages.
Qazvin has been a hotbed of historical developments in Iranian history. In the early years of the Islamic era Qazvin served as a base for the Arab forces. Destroyed by Genghis Khan (13th century), the Safavid monarchs made Qazvin the capital of the Safavid empire in 1548 only to have it moved to Isfahan in 1598. During the Qajar Dynasty and contemporary period, Qazvin has always been one of the most important governmental centers due to its proximity to Tehran.
Bombed and occupied by Russian forces in both World Wars, Qazvin is also where the famous coup d’etat was launched from that led to the rise of the first Pahlavi dynasty in 1921. Qazvin is also situated near Alamut, where the famous Hasan-i Sabbah, founder of the secret Ismaili order of the Assassins, operated from. Qazvin has been able to survive all this turmoil, today having a population of 290,000 (1996).
