Although al-Walid ibn Yazid, known as al-Walid II (r. 743–744), ruled for only a year, he is nonetheless one of the most colorful Umayyad caliphs. A grandson of Abd al-Malik, builder of the Dome of the Rock, he is recorded in historical sources as a proverbial man about town. His behavior was considered so profligate that he was passed over in succession to grandfather's throne. Instead, his uncle Hisham became caliph and al-Walid retired to his desert qasr to pass his time in song and pleasure among a retinue of his favorite drinking companions.
Al-Walid seems to have consistently preferred life in the desert over that in the city. There he focused his attention on literary pursuits, for he was a skilled poet in topics (unsurprisingly) of love, beautiful women, and drinking. A few other surviving poems are vitriolic attacks against his despised uncle Hisham. A number of desert qusur, or palaces, constructed in the later Umayyad period have been associated with his patronage, including Qasr al-Mshatta and Khirbat al-Mafjar.
The enormous size of these buildings and their lavish decoration suggests al-Walid had access to significant funds despite his outsider status. Khirbat al-Mafjar's stucco scultpures of semi-nude women, luxurious floor decorations, and pools make it easy to imagine the contexts for al-Walid's parties in the "Playboy Mansions" of their time.
