This list covers the Sassanid dynasty of Persia from their revolt against the Parthian Arsacids until their extinction by the Arabs. Aggression is high because they regarded themselves as heirs to the Achaemenids and claimed all the territories these had ever owned, unfortunately including most of the contemporary eastern Roman empire. Early depictions show mail-shirted kings and princes with heavy lance and bow charging at the gallop on leather or felt-armoured horses. A limited number of Parthian style cataphracts (4Kn) became available as the former Parthian noble families became assimilated, providing a striking force of lancers in full metal armour incorporating tubular arm and leg defences and masked helmets riding metal-armoured horses. The strength of the army was the asavaran. During the revolt, these may have been Parthian-style horse archers, but as they became minor aristocrats ruling subject peasants, they wore mail shirts, rode horses in full leather or felt protection (or occasionally frontal metal half-armour) and were armed with bow and heavy sword. They shot faster but less powerfully than Huns or Byzantines. The archers mentioned on foot in sieges were probably dismounted asavaran. Peasant levy spearmen with rectangular cane-reinforced rawhide shields were brought for camp labour, but formed a rear line in battle. War elephants are first attested in 337, and could not have been available before 260. They were not used to fight cavalry, but only positioned behind the infantry or to head desperate assaults. Several are reported being killed by Late Roman legionaries and auxilia palatina. They are described as having frontal armour “with terrifying crests” or as carrying towers with archers. Vassal nations provided horse archers and Dailami and other hill tribes mercenary infantry. The most useful guides to Sassanid warfare are the Roman and Byzantine accounts of the army in action.
