Tahirid dynasty
The Tahirid Dynasty was an Iranian Persian dynasty that ruled from 820 to 872 in Khorasan, northeastern Greater Iran, a region now split between Iran, Afghanistan, Tajikistan, Turkmenistan, and Uzbekistan. The Tahirid capital was originally Merv but was moved to Nishapur. The Tahirid dynasty is considered to be the first dynasty independent of the Abbasid caliphate established in Khorasan.
