The Sasanian Empire or Sassanid Empire, officially known as Eranshahr, was the last Iranian empire before the early Muslim conquests of the 7th to 8th centuries. Named after the House of Sasan, it endured for over four centuries, from 224 to 651, making it the second longest-lived Persian imperial dynasty after the Arsacids of the Parthian Empire.
