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.
