Sasanian dynasty
The Sasanian dynasty (also known as the Sassanids or the House of Sasan), the last Persian lineage of rulers to achieve hegemony over much of Western Asia before Islam, ruled between 224 CE–651 CE. The house of Sasan founded the Sasanian Empire of Iran. The dynasty began with Sasan, although it was Ardashir I who named the dynasty in honour of his predecessor (Sasan) and after his tribe, the Sasanians.
