The Iran–Iraq War was fought for nearly eight years and left a lasting legacy on Iran and Iraq. The Battle of al-Qadisiyya was the engagement between the Arab-Muslim army and the Sāsānian Iranian army during the first period of Muslim expansion which resulted in the Arab-Muslim conquest of Iran. In the centuries following the battle, Qādisiyyah became enshrined in Muslim collective memory as a symbol of the successes of early Islamic history. Already during the period of the Crusades, Muslim leaders referred to Qādisiyyah as a point of reference to which they compared their own achievements.[1] Academic studies of the narratives of Qādisiyyah and other early Islamic battles have revealed numerous topoi that make up a common schema of the Arab-Muslim conquests; the generation of these literary layers seems to have begun immediately, as story-tellers (quṣṣāṣ) embellished their narrative in order to create an entertaining story or to glorify past ancestors.[2]
