 The Ghassanid king al-Harith ibn Jabalah (reigned 529–569) supported the Byzantines against Sassanid Persia and was given the title patricius in 529 by the emperor Justinian I. Al-Harith was a Monophysite Christian; he helped to revive the Syrian Monophysite (Jacobite) Church and supported Monophysite development despite Orthodox Byzantium regarding it as heretical.Later Byzantine mistrust and persecution of such religious unorthodoxy brought down his successors, al-Mundhir (reigned 569–582) and Nu'man.The Ghassanids, who had successfully opposed the Persian allied Lakhmids of al-Hirah (Southern Iraq and Northern Arabia), prospered economically and engaged in much religious and public building; they also patronized the arts and at one time entertained the poets Nabighah adh-Dhubyani and Hassan ibn Thabit at their courts.
