Bithynia and Pontus (Latin: Provincia Bithynia et Pontus) was the name of a province of the Roman Empire on the Black Sea coast of Anatolia (Turkey). It was formed by the amalgamation of the former kingdoms of Bithynia (annexed by Rome 74 BC) and Pontus (annexed 63 BC).
The province of "Bithynia and Pontus" was originally two separate kingdoms, among the several successor kingdoms of Alexander the Great's empire.
The Kingdom of Bithynia first achieved Independence from the larger Hellenistic kingdoms in 297 BC under its first king Zipoetes I of Bithynia. Under king Prusias I, Bithynia first came into contact with the Roman Republic. Bithynia remained neutral during Rome's war against the Seleucid Empire and its King Antiochus the Great from 192-188 BC, despite the Seleucid Empire being the long-time enemy of the kingdom.
Prusias I's son and successor, Prusias II of Bithynia, first opened relations with Rome. Following Prusias II's failed invasion of the Roman ally of the Kingdom of Pergamon in 154 BC, Bithynia was forced to pay heavy war reparations. Prusias II sent his son Nicomedes II of Bithynia to Rome to negotiate a reduction in the annual payments. Once in Rome, Nicomedes II gained the favor of the Roman Senate and, following a failed assassination attempt on Nicomedes II's life by his father Prusias II, the Senate supported Nicomedes II in his revolt against his father. Supported by Rome and Pergamon king Attalus II Philadelphus, Nicomedes II overthrew his father and became king in 149 BC and entered into an alliance with Rome.
Nicomedes II would be a loyal ally, actively supporting Rome's interests in the Aegean Sea and Black Sea. In 133 BC, King Attalus III of Pergamon died, bequeathing his kingdom to Rome. However, Eumenes III, claiming to be the illegitimate son of a former Pergamon king, claimed the throne and made war against the Romans. Though the Romans sent the Consul Publius Licinius Crassus Dives Mucianus to enforce their claims in 130 BC, Eumenes III defeated them and killed Crassus. Rome sent a second army in 129 BC under Marcus Perperna to face Pergamon pretender. Supported by forces under Nicomedes II, Perperna was able to defeat Eumenes III and secured Rome's claims in western Anatolia, allowing Rome to annex Pergamon directly as the province of Asia.
First Mithridatic War (89–85 BC)
Becoming king in 127 BC, Nicomedes III conqurered Paphlagonia along the Black Sea and began to expand his influence over the Roman ally of Cappadocia. In 116 BC, the Cappadocian king Ariarathes VI was murdered by the Cappadocian noble Gordius on orders from King Mithridates VI of Pontus. Mithridates VI then installed his sister Laodice of Cappadocia, Ariarathes VI's widow, as regent over for the infant Ariarathes VII, ensuring Pontic control over Cappadocia in the process.
Nicomedes III sought to take advantage of the political power vacuum in Cappadocia, invaded the kingdom, and refused to recoginze the infant Ariarathes VII as Cappadocia's legitimate ruler. Laodice, mother of Nicomedes III's deaseced wife Nysa, then married Nicomedes III to secure his hold over the kingdom. Mithridates VI swiftly invaded Cappadocia to prevent Nicomedes III from claiming the throne, expelled Nicomedes III, restored his nephew Ariarathes VII to the Cappadocian throne, and returned Cappadocia to Pontus' sphere of influence.
Following a rebellion in by Cappadocian nobles in 97 BC against Pontic control, both Nicomedes III and Mithridates VI sent emissaries to Rome in 95 BC asking the Republic to intervene in their struggle for dominance over the kingdom. The Roman Senate did not side with either party, however, and demanded both to withdraw from Cappadocia and ensure its independence.
The next year, in 94 BC, Nicomedes III died and was succeeded by his son, the pro-Roman Nicomedes IV of Bithynia, as king. In 93 BC, ignoring Rome's command to not interfere with Cappadocia's independence, soldiers from the Kingdom of Armenia under Tigranes the Great, son-in-law of Mithridates VI, invaded and conquered Cappadocia at the behest of the Pontic king. With Cappadocia secured, Mithridates VI invaded Bithynia, defeating Nicomedes IV in 90 BC, annexing his kingdom.
Nicomedes IV sought the protection of Rome. Upon arriving in Italy, the Senate sent a delegation to Pontus, demanding Mithridates restore Nicomedes IV to his throne. Though the Social War was still raging in Italy, Rome was able to successfully restore both kings due to the Republic's growing influence in the region.
Once restored to his throne, the Senate encouraged Nicomedes IV to raid Mithridates VI's territories. Mithridates VI invaded Bithynia in 88 BC, again forcing Nicomedes IV to flee to Rome. In response to the ousting of Nicomedes IV and Mithridates VI's growing power, the Senate declared war against Pontus and sent the Consul Lucius Cornelius Sulla east to defeat Mithridates VI. Rome's victory over Mithridates VI in 85 BC and the subsequent Treaty of Dardanos secured Rome as the major power in Anatolia, restored Nicomedes IV to his throne, and further brought Bithynia into closer ties with the Republic.
Third Mithridatic War (73–63 BC)
Due to the internal political struggle between Lucius Cornelius Sulla, Gaius Marius, and Lucius Cornelius Cinna, Rome had been unable to definitively defeat Pontic King Mithridates VI. In 74 BC, King Nicomedes IV of Bithynia died and, hoping to secure his kingdom from further Pontic aggression, bequeathed his kingdom to Rome. The Senate immediately voted to annex the kingdom as a province directly governed by the Republic.
Nicomedes IV's death caused a power vacuum in Asia Minor, allowing Mithridates VI to invade and conquer the leaderless kingdom. With Mithridates VI again having designs on Roman protectorates in Asia Minor, including Bithynia, Rome launched a third war against Pontus. Dispatching Consul Lucius Licinius Lucullus to Asia, Rome drove Pontus and its ally Armenia out of Asia proper, reasserted Roman dominance over Anatolia by 71 BC, and conquered the Kingdom of Pontus.
Mithridates VI then fled to his ally the Kingdom of Armenia, which was invaded by Lucullus in 69 BC. Despite his initial successes, however, Lucullus was under able to bring the war against Pontus to a close as Mithridates VI remained at-large. Recalling Lucullus, the Senate dispatched Gnaeus Pompeius Magnus ("Pompey") to the East to finally defeat Mithridates VI. Arriving in Asia Minor in 65 BC, Pompey decisively defeated Mithridates VI in the Caucasus Mountains of Kingdom of Armenia.
Returning to Anatolia proper in 64 BC, Pompey officially annexed Bithynia and the western half of Pontus (including the Greek cities along the Black Sea) into the Republic as the directly governed province of "Bithynia et Pontus". As for the eastern half of Pontus ("Lesser Armenia"), Pompey added its territory to that of the Kingdom of Galatia under the Roman client king Deiotarus as a reward for his loyalty to Rome.
Republican civil wars
Bithynia and Pontus became an important player during the Roman Republican civil wars. When Julius Caesar crossed the Rubicon River in 49 BC and started his civil war, many of members of the Roman Senate under the leadership of Pompey fled to the East. The Galatian client king Deiotarus, ruler of the rump state of eastern Pontus (Lesser Armenia), sided with his old patron Pompey against Caesar. However, following Pompey's defeated at the Battle of Pharsulus and subsequent death in 48 BC, Deiotarus faced execution by Caesar's forced until the Roman orator Marcus Tullius Cicero pleaded his case and secured his pardon from Caesar. Caesar subsequently named Gnaeus Domitius Calvinus as his chief lieutenant in Asia Minor while Caesar traveled to Ptolemaic Egypt.
With the Caesar in Egypt, Pharnaces II, the Roman client king of the Bosporan Kingdom and the youngest son of Mithridates VI, seized the opportunity and conquered Colchis and Lesser Armenia. The rulers of Cappadocia and Galatia, Ariobarzanes III and Deiotarus respectively, appealed to Calvinus for protection and soon the Roman forces sought battle with Pharnaces II. They met at the Battle of Nicopolis in eastern Anatolia in 48 BC, where Pharnaces II soundly defeated the Roman army and overran much of Cappadocia, Pontus, and Bithynia.
After defeating the Ptolemaic forces at the Battle of the Nile, Caesar left Egypt in 47 BC and travelled through Syria, Cilicia, and Cappadocia to face Pharnaces II. As Pharnaces II gained word of Caesar's approach with his veteran army, he sent envoys to seek a peace, which Caesar refused. Caesar met Pharnaces II at the Battle of Zela, decisively defeating the Pontic king and reassessing Roman dominance over Asia Minor. Upon his return to the Bosporan Kingdom, Pharnaces II was assassinated by his son-in-law Asander. In return, Caesar named Asander as the kingdom's new Roman client king. Caesar then incorporated Lesser Armenia into the Roman client kingdom of Cappadocia to serve as a buffer between Rome's interests in Asia Minor against future aggression from Eastern kingdoms.
In 45 BC, Caesar, now dictator of Rome, appointed Quintus Marcius Crispus as governor of Bithynia and Pontus. Following Caesar's assassination on March 15, 44 BC, by the members of the Roman Senate, Marcus Junius Brutus and Gaius Cassius Longinus fled from Italy and assumed command of the Republic's eastern provinces, including Bithynia and Pontus, in 43 BC. When Crispus refused to serve the assassin of his patron, Cassius had him removed from office and forced into retirement. Following the defeat of Brutus and Cassius by the Second Triumvirate at the Battle of Philippi in 42 BC, Triumvir Mark Antony assumed command of the Republic's eastern provinces.
The Second Triumvirate expired in 33 BC, ending Antony's legal right to govern the Eastern half of the Republic. With the Triumvirate lapsed, the struggle for dominance between Antony and Octavian intensified. As Octavian built up his support in the West, Antony drew ever closer to Egyptian Queen Cleopatra. When Octavian declared war on Egypt, Antony, supported by the Eastern provinces (including Bithynia and Pontus) went to Egypt's aid against Octavian. Octavian's victory over Antony at the Battle of Actium in 31 BC ensured Octavian's position as undisputed master of the Roman world. In 27 BC, Octavian became "Augustus": the first Roman Emperor.
In 39 BC, Antony stripped control of Lesser Armenia (the remnants of the former Kingdom of Pontus) from the rulership of the Cappadocian king Ariarathes X of Cappadocia and made Darius of Pontus, son of Pharnaces II of Pontus, the Roman client king of Pontus. Antony also granted to Darius the rulership of the Roman client kingdom of Cilicia. His reign lasted until his death in 37 BC, after which Antony appointed Polemon I of Pontus as client king of Cilicia and Arsaces of Pontus as client king of Lesser Armenia.
Following Arsaces' untimely death the next year in 36 BC, Antony appointed Polemon I as client king of Pontus. Years later, in 16 BC, Polemon I, at the request of Marcus Vipsanius Agrippa and with the approval of Roman Emperor Augustus, married Queen Dynamis of the Bosporan Kingdom, becoming ruler of that realm in addition to Pontus and Cilicia. Polemone I would later add Colchis to his realm of client kingdoms he ruled on behalf of Rome.
Following Polemon I's death in 8 BC, he was succeeded by his stepson Tiberius Julius Aspurgus as client king of the Bosporan Kingdom and by his second wife Pythodorida of Pontus became client queen of Pontus, Cilicia, and Colchis. Pythodorida would marry then King Archelaus, the Roman client king of Cappadocia, in 8 BC, thereby joining the several eastern client kingdom under a single family. Following Archelaus' death in 14 AD and the subsequent transformation of Cappadocia into a directly governed province in 18 AD, Pythodorida lost her title as queen of Cappadocia.
Pythodorida was succeeded by her stepson Polemon II of Pontus following her death in 38 AD. Polemon II ruled as a Roman client king over Pontus and Cilicia until the Roman Emperor Nero deposed him in 62 AD. Cilicia was then annexed into a directly governed Roman province and Pontus was re-incorporated in Cappadocia, then a directly governed Roman province.
As part of the Constitutional Reforms of Augustus which transformed the Roman Republic into the Roman Empire all Roman provinces where divided into imperial provinces and senatorial provinces. Imperial provinces were those border provinces which required a permanent military presence to protect the Empire from invasion. As such, only the Emperor (as supreme commander of the army) had the right to appoint the governors of those provinces.
Senatorial provinces, conversely, were centered along the Mediterranean Sea and did not possess any significant military force. Augustus allowed the Senate to appoint the governors of these provinces as it had done with all provinces under the Republican system. The province of Bithynia and Pontus, as not being a border province and lacking a size able military force, was classified by Augustus as a senatorial province. Despite this official designation, the distinction between senatorial and imperial provinces quickly began to blur, with the Emperor ultimately appointing the governors of all provinces by the 1st century AD.
Under the administrative reforms of emperor Diocletian, Bithynia and Pontus was divided into 3 smaller provinces: Bithynia, Honorias, and Paphlagonia. These belonged to the diocese of Pontica, in turn part of the Prefecture of the East.
Following the Muslim invasions of the 640s AD, the Byzantine Empire reorganized its provincial structure into themes. The province of Bithynia and Pontus was reorganized into the Bucellarian, Opsikion, and Optimatoi themes.
