The Saffarid dynasty was a Sunni Persian] dynasty from Sistan that ruled over parts of Greater Iran, with its capital at Zaranj (a city now in southwestern Afghanistan), from 861 to 1003. One of the first indigenous Persian dynasties to emerge after the Islamic conquest, the Saffarid dynasty was part of the Iranian Intermezzo. The dynasty's founder was Ya'qub bin Laith as-Saffar. A native of Sistan and a local ayyār, Ya'qub worked as a coppersmith (ṣaffār) before becoming a warlord. He seized control of the Sistan region and began conquering most of Iran and Afghanistan, as well as parts of Pakistan, Tajikistan and Uzbekistan.
