The Roman–Persian Wars, also known as the Roman–Iranian Wars, were a series of conflicts between states of the Greco-Roman world and two successive Iranian empires: the Parthian and the Sasanian. Battles between the Parthian Empire and the Roman Republic began in 54 BC; wars began under the late Republic, and continued through the Roman and Sasanian empires. A plethora of vassal kingdoms and allied nomadic nations in the form of buffer states and proxies also played a role. The wars were ended by the early Muslim conquests, which led to the fall of the Sasanian Empire and huge territorial losses for the Byzantine Empire, shortly after the end of the last war between them.
The Iberian War was fought from 526 to 532 between the Byzantine Empire and the Sasanian Empire over the eastern Georgian kingdom of Iberia—a Sasanian client state that defected to the Byzantines. Conflict erupted among tensions over tribute and the spice trade.
The siege of Amida occurred in 502–503, during the Anastasian War. The city was not garrisoned by any troops of the Byzantine Empire but nevertheless resisted for three months before falling to the military of the Sasanian Empire under Kavadh I. According to the detailed account of Zacharias Rhetor, the city's sack was particularly brutal, and accompanied by a massacre of the population for three days and nights. The fall of the city urged the Emperor Anastasius I Dicorus to react militarily, before a truce was agreed between both parts in 505.
