The Khorshidi dynasty, Abbasi dynasty or Atabaks of Little Lorestan (1184–1597) was a Lor dynasty that ruled Little Lorestan in the later Middle Ages from their capital Khorramabad. They were neighbours of the Hazaraspids who ruled over Greater Lorestan. While the Hazaraspids were more politically important because of their vast territory and the fact that they held major communications routes, the Khorsidi dynasty would become a significant power during the Safavid era due to the end of the Hazaraspids. The Khorsidi dynasty remained an important player in the rivalry between the Safavids and the Ottomans.
