The Samanid Empire (Persian: سامانیان, romanized: Sāmāniyān) was a Persianate Sunni Muslim empire, ruled by a dynasty of Iranian dehqan origin, from 819 to 999. The empire was centred in Khorasan and Transoxiana, at its greatest extent included northeastern Iran and Central Asia.
Four brothers: Nuh, Ahmad, Yahya, and Ilyas, founded the Samanid state. Each of them ruled territories under Abbasid suzerainty. In 892, Ismail Samani, united the Samanids under his rule, thus effectively putting an end to the feudal system used by the Samanids. It was also under him that the Samanids became independent of the Abbasids. However, by 945, the government had fallen under the de facto control of the Turkic military slave faction, and the Samanid family's authority had become purely symbolic.
