Historicity of the Samangan town dates to the time of the Kushan Empire during the 4th and 5th centuries when it was a famous Buddhist centre. Witness to this period is seen now in the form of ruins at a place called the Takht-e-Rostam, which is located 3 km from the town on a hilltop. Arabs and Mongols came to this place when it was already famous as a Buddhist religious centre. Aibak was the name given to this place when, during the medieval period, caravans used to stop here.
