Background In 539 Khosrow had originally attempted to gain a casus belli against the Byzantines by trying to take advantage of a disagreement between his Lakhmid clients and the Byzantine clients Ghassanids, who both claimed ownership of the lands south of Palmyra, near the old Strata Diocletiana.; ; . His attempt was, however, thwarted when the Byzantines successfully equivocated the problem. Subsequently, Khosrow accused Justinian of trying to bribe the Lakhmid ruler al-Mundhir III ibn al-Nu'man () through his diplomat Summus, and also that he had emboldened some Huns to make incursions into Iran. The Ghassanid ruler al-Harith ibn Jabalah () invaded Mundhir's territory and carried off rich booty. Khosrow complained to Justinian about this incident, and requested that the stolen riches be returned to him, including payment for the Arabs that had been killed during the attack. His request was, however, ignored. This incident, along with the support by an emissary from the Ostrogoth king Vitiges, and the Armenians living in Byzantine territory being dissatisfied with their rule, encouraged Khosrow to renew the war against the Byzantines. Justinian's ceaseless wars in North Africa and Italy must have contributed to Khosrow's aspirations as well. Justinian, informed of Khosrow's intention for war, tried to dissuade him, but to no avail.
