after wintering in antioch during 115/116  – and, according literary sources, barely escaping violent earthquake claimed life of 1 of consuls, m. pedo virgilianus – trajan again took field in 116, view conquest whole of mesopotamia, overambitious goal backfired on results of entire campaign. according modern historians, aim of campaign of 116 achieve preemptive demonstration aiming not toward conquest of parthia, tighter roman control on eastern trade route. however, overall scarcity of manpower roman military establishment meant campaign doomed start. noteworthy no new legions raised trajan before parthian campaign, maybe because sources of new citizen recruits over-exploited.


as far sources allow description of campaign, seems 1 roman division crossed tigris adiabene, sweeping south , capturing adenystrae; second followed river south, capturing babylon; trajan himself sailed down euphrates dura-europos – where triumphal arch erected in honour – through ozogardana, erected tribunal still seen @ time of julian apostate s campaigns in same area. having come narrow strip of land between euphrates , tigris, dragged fleet overland tigris, capturing seleucia , parthian capital of ctesiphon.


he continued southward persian gulf, when, after escaping fleet tidal bore on tigris, received submission of athambelus, ruler of charax. declared babylon new province of empire , had statue erected on shore of persian gulf, after sent senate laurelled letter declaring war @ close , bemoaning old go on further , repeat conquests of alexander great. since charax de facto independent kingdom connections palmyra described above, trajan s bid persian gulf may have coincided palmyrene interests in region. hypothesis rulers of charax had expansionist designs on parthian babylon, giving them rationale alliance trajan. parthian summer capital of susa apparently occupied romans.


according late literary sources (not backed numismatic or inscriptional evidence) province of assyria proclaimed, apparently covering territory of adiabene. measures seem have been considered regarding fiscal administration of indian trade – or payment of customs (portoria) on goods traded on euphrates , tigris. possible streamlining of administration of newly conquered lands according standard pattern of roman provincial administration in tax collecting, requisitions , handling of local potentates prerogatives, triggered later resistance against trajan.


according modern historians, trajan might have busied himself during stay on persian gulf ordering raids on parthian coasts, probing extending roman suzerainty on mountaineer tribes holding passes across zagros mountains iranian plateau eastward, establishing sort of direct contact between rome , kushan empire. no attempt made expand iranian plateau itself, roman army, relative weakness in cavalry, have been @ disadvantage.

however, trajan left persian gulf babylon – where intended offer sacrifice alexander in house had died in 323 bc – a sudden outburst of parthian resistance, led nephew of parthian king, sanatruces, had retained cavalry force, possibly strengthened addition of saka archers, imperilled roman positions in mesopotamia , armenia, trajan sought deal forsaking direct roman rule in parthia proper, @ least partially.


trajan sent 2 armies towards northern mesopotamia: first, under lusius quietus, recovered nisibis , edessa rebels, having king abgarus deposed , killed in process, while second, under appius maximus santra (probably governor of macedonia), defeated, santra being killed. later in 116, trajan, assistance of quietus , 2 other legates, marcus erucius clarus , tiberius julius alexander julianus, defeated parthian army in battle sanatruces killed. after re-taking , burning seleucia, trajan formally deposed parthian king osroes , put own puppet ruler parthamaspates on throne. event commemorated in coin presented reduction of parthia client kingdom status: rex parthis datus, king given parthians . done, trajan retreated north in order retain of new provinces of armenia – where had accepted armistice in exchange surrendering part of territory sanatruces son vologeses , mesopotamia.
