The Samanids were a Persian state that reigned for 180 years, encompassing a vast territoriy stretching from Central Asia to West Asia. The Samanids were descendants of Bahram Chobin, and thus descended from the House of Mihrān, one of the Seven Great Houses of Iran. In governing their territory, the Samanids modeled their state organization after the Abbasids, mirroring the caliph's court and organization. They were rewarded for supporting the Abbasids in Transoxania and Khorasan, and with their established capitals located in Bukhara, Balkh, Samarkand, and Herat, they carved their kingdom after defeating the Saffarids.
