John Komnenos Raoul Doukas Angelos Petraliphas (Greek: Ἱωάννης Κομνηνός Ῥαούλ Δούκας Ἄγγελος Πετραλίφας; died c. 1274) was a Byzantine noble and military commander during the reign of Emperor Michael VIII Palaiologos (r. 1259–1282).
[1][2][3] The Raoul, as all families of the traditional aristocracy, suffered under Theodore II Laskaris (r. 1254–1258) who sought to reduce the nobility's power and influence.
After the subsequent usurpation of Michael VIII Palaiologos (r. 1259–1282), they were rewarded with high state offices: following his military successes in the next few years, John was named protovestiarios, inheriting the title from George Mouzalon.
Their achievements, however, were quickly undone by John Doukas, the bastard son of the Epirote ruler.
[8][9] In 1261, John married Theodora Palaiologina Kantakouzene, the niece of Michael VIII and widow of George Mouzalon.
