The Nasrid dynasty, also referred to as the Later Saffarids of Seistan or the Maliks of Nimruz, was an Iranian Sunni dynasty that ruled Sistan in the power vacuum left by the collapse of the Ghaznavid Empire and until the Mongol invasion of Central Asia. The Nasrids were a branch of the Saffarid dynasty, and the establishment of the Nasrid Kingdom at Nimruz in 1068 until its dissolution in 1225 represents a transient resurgence of Saffarid rule in Sistan.
