The ancient Greek writings introduced Qazvin as “Razhya” and then in European writings was  it noticed as the ancient city “Rsas” or “Rsasya”. Parthian used to name Qazvin after the name of its founder “Ardpa” and Sassanian named the city “Kashvyn” (the land that should not be missed/ignored). In some versions, the name of the city is “Qasvyn” (the city where the people are full of strength and firm). However, the historians and archaeologists of the present era believe that Qazvin originates from “Caspian” and is the Arabic word of “Caspian”. They believe that Caspians were the people who lived on the shores of the Caspian Sea and moved over and founded the city of Qazvin. That’s why the in old Ottoman and Arabic texts the “Caspian Sea” is mentioned as “Bahr al-Qazvin” which literally means the Sea of Qazvin.

Hundreds of ancient hills have been identified in Qazvin region and Sagzabad Hill has been know as the very early settlement of Iran, 9000 years ago.

Referring to the historical documents the construction of Qazvin is attributed to Shapur II of Sassanid Dynasty. In 1090, Ismaili state was founded in Qazvin with capturing the impregnable fortress of Alamut , and the their reign  continued up to 1256. Ismailis command center was the city of Qazvin, and their major activity was fighting against Abbasid caliphs and the Mongol tribes. Hassan Sabah as the prominent ruler of Ismailis could extend his power to the current Syria with extensive advertising among the poor farmers in the basin. Finally, after 200 years of Ismaili government-ship, Ismaili state was destroyed by Holagu Khan in the invasion of Mongolians.

Tahmasp II from Safavid Dynasty in 1546 chose Qazvin as the capital because of the close proximity of the city of Tabriz to Ottoman borders and its vulnerability as well as being far from Khorasan and continuous invasions of the Uzbeks. Qazvin remained the capital until 1597 (for half a century).
