What is "shahrbaraz"

Shahrbaraz or Shahrvaraz ( Middle Persian: Šahrwarāz) (died 9 June 630) was king of the Sasanian Empire from 27 April 629 to 9 June 630. He usurped the throne from Ardashir III, and was killed by Sasanian nobles after forty days. Before usurping the Sasanian throne he was a general ( spahbed) under Khosrau II (590–628). He is furthermore noted for his important role during the climactic Byzantine–Sasanian War of 602–628, and the events that followed afterwards. His name Shahrbaraz is actually an honorific title, and means "the Boar of the Empire", attesting to his dexterity in military command and his warlike person, as the boar was the animal associated with the Zoroastrian Izad Vahram, the epitome of victory.
