The Parthian period (ca.129 BC-224 AD)
The coming of the Parthians changed Mesopotamia even less than the establishment of the Seleucid kingdom had, for as early as the middle of the 2nd century BC local dynasts had proclaimed their independence. There is no evidence indicating whether the cities of Mesopotamia surrendered piecemeal or all at once or whether they submitted voluntarily or after fighting. In any case, Seleucia was treated better by the Parthians than it had been by the Seleucids, and the local government retained its autonomy. Parthian troops did not occupy Seleucia but remained in a garrison site called Ctesiphon near Seleucia; it later grew into a city and replaced Seleucia as the capital. In Characene in southern Mesopotamia a Seleucid satrap with an Iranian name, Hyspaosines, issued coins about 125 BC, a sign of his independence; the actual date for this may have been earlier. He changed the name of the city Antiochia on the lower Tigris to Spasinou Charax, meaning "The Fort of Hyspaosines," and made it his capital. All the coins issued from his capital have Greek legends. His troops moved north and occupied Babylon and Seleucia probably sometime in 127 BC, when the Parthians were fighting nomadic invaders in the eastern part of their territory. His rule there must have been short, however, for the Parthian governor of Babylon and the north, Himerus, was back in Seleucia and Babylon by 126. Himerus could not have been a rebel, since he struck coins in the name of the Parthian rulers Phraates II and Artabanus II, both of whom were killed in fighting in eastern Iran. Himerus abused his power and is said to have oppressed the cities of Mesopotamia, plundering them and killing their inhabitants. Cuneiform documents from Babylon stop after this date, indicating that the city did not survive the depredations of Himerus. He vanished, however, and Parthian sovereignty was restored by the ninth Arsacid king, Mithradates II, who came to the throne about 124 BC; he was the son of Artabanus II. Mithradates II recovered all Mesopotamia and conquered Characene, overstriking coins of Hyspaosines and driving him from his capital in 122 or 121 BC. By 113, if not earlier, Dura-Europus on the Euphrates was in Parthian hands. In 95 BC the Armenian king Tigranes II, a hostage at the court of Mithradates, was placed on the throne of Armenia by his Parthian overlord, and the small kingdoms of northern Mesopotamia--Adiabene, Gordyene, and Osroene--gave allegiance to Mithradates. Mithradates II died about 87 BC, although he may have died earlier, since the period after 90 BC is dark and a usurper named Gotarzes may have ruled for a few years in Mesopotamia. During the reign of Mithradates II the first contacts with Rome, under Lucius Cornelius Sulla, were made, and portents of future struggles were evident in the lack of any agreement between the two powers. Sulla was sent to the east by the Roman Senate to govern Cilicia in Anatolia. In 92 BC Orobazes, an ambassador from Mithradates II, came to him seeking a treaty, but nothing was concluded, since instructions from Rome did not include negotiations with the Parthian power.
Tigranes II took advantage of struggles between several claimants to the Parthian throne to expand Armenian territory into Mesopotamia, and the small states in the north gave him their allegiance. It was not until 69 BC, when the Roman general Lucius Licinius Lucullus captured Tigranokerta, Tigranes' capital, that Mesopotamia returned to Parthian rule. Thereafter wars between the Romans and the Parthians were to dominate the political history of Mesopotamia.
The Parthians left the local administrations and rulers intact when they conquered Mesopotamia. According to Pliny the Elder (Natural History VI. 112) the Parthian empire consisted of 18 kingdoms, 11 of which were called the upper kingdoms (or satrapies), while 7 were called lower kingdoms, meaning that they were located on the plains of Mesopotamia. The centre of the lower kingdoms was ancient Babylonia, called Beth Aramaye in Aramaic, and it was governed directly by the Parthian ruler. In the south was Characene, while to the northeast of Ctesiphon, which had supplanted Seleucia as the Parthian capital, was Garamea, with its capital at modern Kirkuk. Adiabene had Arbela as its capital, and farther north was a province called Beth Nuhadra in Aramaic, which seems to have been governed by a general who was directly responsible to the Parthian king, because this province bore the brunt of Roman invasions. Nisibis was the main city of the desert area of Arabistan, but at the end of the Parthian period the desert caravan city of Hatra claimed hegemony over this area. There were other principalities in the northwest: Sophene, where Tigranes' capital was located; Gordyene and Zabdicene (near modern Çölemerik in eastern Turkey), located to the east of Sophene; and Osroene, with its capital Edessa (modern Urfa, in Turkey.), which lay inside the Roman sphere of influence. Rule over so many small kingdoms gave Mithradates II the title "King of Kings," also borne by later Parthian rulers.
The defeat of the Roman legions under Marcus Licinius Crassus by the Parthians at the Battle of Carrhae (Carrhae is the Roman name for Harran) in 53 BC heralded a period of Parthian power and expansion in the Middle East, but the tide turned under Mark Antony in 36-34 BC, and thereafter the power structure in the east remained volatile, with the two great states, Rome and Parthia, contending for predominance in the region. Armenia was a perennial bone of contention between the two powers, each of which sought to put its candidate on the throne.
Parthian rule was not firm over all Mesopotamia; thus, for example, during the reign of Artabanus III (AD 12-38) the Jewish brigands Asinaeus and Anilaeus set up a free state north of Ctesiphon that lasted 15 years before it was overcome by the Parthians. With the end of cuneiform records and with the attention of classical sources turned to the wars between the Romans and the Parthians, information about internal affairs in Mesopotamia becomes almost nonexistent. Hellenism continued to flourish, for many Parthian kings had the epithet "Philhellene" placed on their coins, but during the last two centuries of Parthian rule Greek influences declined in favour of Iranian ones, while central authority suffered from the usurpations of powerful nobles and local kings. From coinage it is known that the city of Seleucia revolted against central control at the end of Artabanus' reign and maintained its independence for a number of years. Peace was broken by the Roman emperor Nero, who sought to put his client on the throne of Armenia, but, after several years of conflict, peace was arranged in 63. Vologeses I (c. AD 51-80) founded the city Vologesias, near Seleucia, as his capital, but the whole area (including Ctesiphon and Seleucia) became an urban complex called Mahoze in Aramaic and Al-Mada'in in Arabic; both names mean "The Cities." See the ruins of Ctesiphon
Internal rivalries in the Parthian state gave the Romans an opportunity to attack, and control over Armenia was the casus belli for the Roman emperor Trajan's advance into Mesopotamia in 116. Adiabene, as well as the entire Tigris-Euphrates basin of northern Mesopotamia, was incorporated as a province into the Roman Empire. Trajan advanced to the Persian Gulf, but he died of illness and his successor Hadrian made peace, abandoning the conquests in Mesopotamia, although client states remained.
The second century of the Common era was a dark period in Parthian history, but it was a time of growth in wealth and influence of the caravan cities of Palmyra, Hatra, and Mesene (formerly Characene, situated at the confluence of the Tigris and Euphrates). Armenia continued to be a bone of contention between the two great powers, and hostilities occasionally flared up. In 164-165 the Roman general Gaius Avidius Cassius captured the capital cities Ctesiphon and Seleucia, but an epidemic forced the Romans to retreat and peace was restored. Returning soldiers spread the disease throughout the Roman Empire, with devastating consequences. The terms of peace favoured the Romans, who secured control of Nisibis and the Khabur River valley. The next great war was the invasion of the Roman emperor Septimius Severus to punish the Parthians, who had supported his rival Pescennius Niger and had annexed some territory in Mesopotamia in return for their support. Severus took and sacked Ctesiphon in 198. Because the devastated countryside contained no supplies for the Romans, they were soon compelled to retreat. A siege of Hatra in 199 by Severus failed, and peace was made. Conflict between two claimants to the Parthian throne, Vologeses IV or V and Artabanus V, gave the Roman emperor Caracalla an excuse to invade Adiabene, but in 217 he was assassinated on the road from Edessa to Carrhae( Harran), and the Romans made peace. The end of the Parthian kingdom was near, and the advent of the Sasanians brought a new phase in the history of Mesopotamia.
Parthian rule brought little change in the administration and institutions of Mesopotamia as it had existed under the Seleucids, except for a general weakening of central authority under the feudal Parthians. The Parthians instituted a new era, beginning in 247 BC, but it paralleled rather than replaced the Seleucid era of reckoning, and the Parthian vanished at the end of the dynasty. As far as can be determined, Hellenism was never proscribed under the Parthians, although it grew weaker toward the end of Parthian rule. From archaeological surveys around Susa, located in the kingdom of Elymais in modern Khuzestan, and from the Diyala plain northeast of Ctesiphon, it seems that the population of the land increased greatly under the Parthians, as did trade and commerce. The coinage of the later Parthian rulers became more and more debased, probably as a result of the many internecine wars and the lack of control by the central authority. Local rulers also issued their own coinages in Persis, Elymais, Mesene, and elsewhere.
Changes took place in the demography of Mesopotamia under the Parthians, and perhaps the most striking development among the population was the increase of Arab infiltration from the desert, which resulted in Arab dynasties in the oasis settlements of Palmyra and Hatra. Similarly, an influx of Armenian settlers in the north changed the composition of the local population. After the fall of the Temple of Jerusalem to the Romans in 70, many Jews fled to Mesopotamia, where they joined their coreligionists; Nehardea, north of Ctesiphon, became a centre of Jewish population. Naturally also many migrants from the east came to Mesopotamia in the wake of the Parthian occupation. With many merchants from east and west passing through or remaining in Mesopotamia, the population became more diverse than it had previously been.
During the Parthian occupation the ancient religion and cults of Mesopotamia came to an end and were replaced by mixed Hellenic and Oriental mystery religions and Iranian cults. Local Semitic cults of Bel, Allat, and other deities flourished alongside temples dedicated to Greek gods such as Apollo. The sun deity Shamash was worshiped at Hatra and elsewhere, but the henotheism of the ancient Middle East was giving way to acceptance of universalist religions, if the prevalent view cannot yet be called one of monotheism. In Mesopotamia, in particular, the influence of Jewish monotheism, with the beginning of rabbinic schools and the organization of the community under a leader, the exilarch (resh galuta in Aramaic), must have had a significant influence on the local population. Toward the end of the reign of Artabanus III, the royal family of Adiabene converted to Judaism. In the first two centuries of the Common era, Christianity and various baptismal sects also began to expand into Mesopotamia. So far no Mithraeums (underground temples for the worship of the god Mithra), such as existed in the Roman Empire, have been found in Mesopotamia, except at Dura-Europus, where Roman troops were stationed. Many local cults and shrines, such as that of the Sabians and their moon deity at Harran, however, continued to exist until the Islamic conquest. Parthian Zoroastrianism reinforced local Zoroastrian communities in Mesopotamia left from the time of the Achaemenians, and one of the Gnostic baptismal religions, Mandaeanism, which is still in existence, had its beginning at this time. Although Christian missionaries were active in Mesopotamia in the Parthian period, no centres, such as the one established later at Nisibis, have been reported, and it may be supposed that their activity at first was mainly confined to Jewish communities.
Archaeological evidence indicates that the Parthians had a more marked influence on art and architecture. Local schools of art flourished, and at first Greek ideals predominated, but in the last two centuries of Parthian rule a "Parthian style" is evident in the art recovered from Mesopotamia and other regions. Whereas Achaemenian and Sasanian art are royal or imperial and monumental, Parthian art, like Seleucid art, can be characterized as "popular." Parthian works of art reflect the many currents of culture among the populace, and one may say that it is expressionist and stylized, in contrast with Greek and Roman naturalistic or realistic art. The characteristics of Parthian art in Mesopotamia are total frontality (i.e., the representation of figures in full face) in portraits, along with an otherworldly quality. In Middle Eastern art from previous periods, figures were almost always shown in profile. Another new feature of Parthian art is the frequent portrayal of the "flying gallop" in sculpture and painting, not unexpected in view of the importance of cavalry and mounted archers in the Parthian armies. Likewise, Parthian costume, with baggy trousers, became the mode over much of the Middle East and is portrayed in painting and sculpture. In architecture the use of ayvans (arches in porticoes) and domed vaults is attributed to the Parthian period; they may have originated in Mesopotamia. Parthian art influenced that of the Nabataeans in Roman territory, as it did others throughout the Middle East.
Parthian was an Iranian language written in the Aramaic alphabet. It had an enormous number of words and even phrases that were borrowed from Aramaic, and scribal training was necessary to learn these. Syriac, being a Semitic language with emphasis on consonants, evolved several alphabets based on the Aramaic alphabet. The Aramaic alphabet was better suited to Syriac than to Parthian phonology. Parthian was therefore difficult to read and was mainly used by scribes or priests for official or religious writings.
The largest lacuna is in literature from the Parthian period. The largely oral literature of the Parthians, famous for their minstrels and poetry, does not seem to have found many echoes in Mesopotamia, where the settled society contrasted with the heroic, chivalric, and feudal society of the Iranian nomads that continued to dominate Parthian mores even after they had settled in Mesopotamia. Nonetheless, the end of the Parthian period saw the beginning of Syriac literature, which is Christian Aramaic, and some of early Syriac literature, such as the "Song of the Pearl," contains Parthian elements. In the realm of language, rather than literature, the writing of Aramaic changes to Parthian in the 2nd century AD, as can be seen from a bilingual (Greek and Parthian) inscription on a bronze statue from Seleucia dated AD 150-151. It tells how Vologeses III defeated the king of Mesene and took over the entire country. After this period one no longer speaks of Aramaic, but of Parthian and Syriac written in a new cursive alphabet.
