Saffarid dynasty

The Saffarid dynasty (Persian: سلسله صفاریان‎‎) was a Muslim Persianate dynasty from Sistan that ruled over parts of eastern Iran, with its capital at Zaranj (a city now in southwestern Afghanistan).Khorasan, Afghanistan and Balochistan from 861 to 1003. The dynasty, of Persian origin, was founded by Ya'qub bin Laith as-Saffar, born in 840 in a small town called Karnin (Qarnin), which was located east of Zaranj and west of Bost, in what is now Afghanistan - a native of Sistan and a local ayyar, who 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, Tajikestan and Uzbekistan.

The Saffarids used their capital Zaranj as a base for an aggressive expansion eastward and westward. They first invaded the areas south of the Hindu Kush in Afghanistan and then overthrew the Persian Tahirid dynasty, annexing Khorasan in 873. By the time of Ya'qub's death, he had conquered the Kabul Valley, Sindh, Tocharistan, Makran (Balochistan), Kerman, Fars, Khorasan, and nearly reached Baghdad but then suffered a defeat by the Abbasids.
