Archeological findings in the Qazvin plain reveal the existence of urban agricultural settlements as far back as 7000 BC. The name “Qazvin” or “Kasbin” is derived from Cas, an ancient tribe that lived south of the Caspian Sea millennia ago. 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.
