Ya'qub-i Laith Saffari

Ya'qub ibn al-Layth al-Saffar or Ya'qub-i Laith Saffari (Oct 25, 840-June 5, 879) (Persian: یعقوب لیث صفاری‎), a Persian coppersmith, was the founder of the Saffarid dynasty in Sistan, with its capital at Zaranj (a city now in south-western Afghanistan). He ruled territories that are now in Iran and Afghanistan, as well as portions of western Pakistan. He was succeeded by his brother, Amr Saffari.

In Iranian folklore, Ya'qub is sometimes regarded as an Iranian Robin Hood because according to legend he stole from the wealthy and helped the poor.
