Sasanian EmpireThe Sasanian Empire (səˈsɑːniən,_səˈseɪniən), officially known as Eranshahr ("Land/Empire of the Iranians"), was the last Iranian empire before the early Muslim conquests of the 7th–8th centuries AD. Named after the House of Sasan, it endured for over four centuries, from 224 to 651 AD, making it the longest-lived Persian imperial dynasty. The Sasanian Empire succeeded the Parthian Empire, and re-established the Persians as a major power in late antiquity alongside its neighbouring arch-rival, the Roman Empire (after 395 the Byzantine Empire).
