The Ismailis of the Badkahshan region of Tajikistan and Afghanitan constitute an important part of the Shi‘a Ismaili Muslim community today, with a distinctive socio-cultural heritage of their own. This heritage, shaped by both history and geography, has preserved their faith for more than a thousand years. Nasir Khusraw, the famous Ismaili da‘i, theologian, philosopher and poet from the 5th century AH/11th century CE, was probably the most influential person in the formation of the Ismaili community in this region.
