The name "Qazvin" or "Kasbin" is derived from Cas, an ancient tribe that lived south of the Caspian Sea millennia ago.

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 invaders. Destroyed by Genghis Khan (13th century), the Safavids monarchs made Qazvin the capital of the Safavid Empire in 1548 only to have it moved to Esfahan 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 Reza Shah of Pahlavi dynasty in 1921. Qazvin is also situated near Alamut, where the famous Hasan-e Sabbah, founder of the Ismaili order of the Assassins, operated from.
