From our vantage point in the 21st century, it is clear that Haroon al Rashid is by far the most famous Arab caliph. His renown is not some modern phenomenon either: he may occasionally pop up as a cultural reference or on a trivia show, but he was immortalized early in the epic One Thousand and One Nights. His time in charge is generally thought of as the height of Arab power and culture, a claim we will investigate together in our many episodes on the legendary figure.
