Haroon al Rashid is commonly portrayed as a martial caliph, one who menaced the Byzantine empire and led a tireless crusade against them. He is praised in Arab sources for defeating the Greeks time and again, all in defense of the umma’s faith and faithful. While this popular opinion isn’t entirely mistaken, it is remarkably exaggerated, a curiosity which itself deserves special attention. The caliphate’s forces dominated the battlefield, but no tangible gains were made despite their sustained success in war.
