Alexander the Great ?s military campaign to conquer the Achaemenid empire included a propaganda campaign to convince the Iranians his kingship was compatible with their religious and cultural norms. This campaign proved so successful that the overt display of Alexander ?s Iranian and Zoroastrian preferences alienated some of his Greek and Macedonian allies. Parivash Jamzadeh shows how this original propaganda material displayed multiple layers of Iranian influences. Additionally she demonstrates that the studied sources do not always offer an accurate account of the contemporary Iranian customs, and occasionally included historical inaccuracies. One of the most interesting finds in this study is the confusion of historical sources that arose between the opponents Darius III and Alexander. Jamzadeh argues that the Iranian propaganda regarding Alexander the Great has contributed to this confusion.
