Shahrbaraz (also spelled Shahrvaraz or Shahrwaraz; New Persian: شهربراز), was shah (king) of the Sasanian Empire from 27 April 630 to 9 June 630. He usurped the throne from Ardashir III, and was killed by Iranian nobles after forty days. Before usurping the Sasanian throne he was a spahbed (general) under Khosrow 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.
