The First Mithridatic War (89–85 BC) was a war challenging Rome's expanding Empire and rule over the Greek world. In this conflict, the Kingdom of Pontus and many Greek cities rebelling against Rome were led by Mithridates VI of Pontus against the Roman Republic and the Kingdom of Bithynia. The war lasted five years and ended in a Roman victory which forced Mithridates to abandon all his conquests and return to Pontus. The conflict with Mithridates VI would continue in two further Mithridatic Wars.

Prelude

Following his ascension to the throne of Kingdom of Pontus, Mithridates VI of Pontus focused on expanding his kingdom. Mithridates' neighbors however were Roman client states, and expansion at their expense would inevitably lead him to conflict with Rome. After successfully incorporating most of the coast around the Black Sea into his kingdom, he turned his attention towards Asia Minor, in particular the Kingdom of Cappadocia, where his sister, Laodice was Queen. Mithridates had his brother-in-law, Ariarathes VI assassinated by Gordius (a Cappadocian nobleman who was allied with Mithridates) leaving the Kingdom in the hands of Laodice, who ruled as regent for her son Ariarathes VII of Cappadocia.

Laodice married Nicomedes III of Bithynia, whose country was Pontus' traditional enemy. Nicomedes occupied Cappadocia and Mithridates retaliated by driving him out of Cappadocia and establishing himself as patron of his nephew's kingship on the throne. When Ariarathes refused to welcome Gordius back, Mithridates invaded Cappadocia again and killed Ariarathes. He proceeded to place his son also called Ariarathes on the throne of Cappadocia under the guardianship of Gordius.

Nicomedes appealed to the Roman Senate, which decreed that Mithridates be removed from Cappadocia and Nicomedes be removed from Paphlagonia and the Senate appointed Ariobarzanes I of Cappadocia as King of Cappadocia. Mithridates prompted his son-in-law Tigranes the Great of Armenia to invade Cappadocia and remove Ariobarzanes.

The Aquillian legation, 90-89 BC

In the late summer 90 BC a Senatorial legation was sent east, under Mn. Aquillius and Manlius Maltinus, to restore Nicomedes and Ariobarzanes to their kingdoms. ^[1] The Senate also sent instructions to Cassius "the commander of Asia about Pergamon who had a small army" and to Mithridates Eupator himself to assist in this.^[2]

Cassius' small army was probably the standard peace-time garrison force of between a whole and half legion (5 to 10 cohorts) and a few local auxiliary units - certainly no more than 5,000 troops in all. The Aquillian legation soon augmented it with a large force of Galatian and Phrygian auxiliary regiments and with these troops proceeded to restore both monarchs. Mithridates, angry with the Romans, refused to cooperate but neither did he offer opposition and both kings were restored without any fighting in about the autumn 90 BC.^[3]

Its mandate achieved, the Aquillian legation ought to have gone home in winter 90-89. Instead, no doubt on the excuse of keeping Mithridates under observation, it began to work upon Marius' covert instructions to Aquillius of provoking the Pontic King to war. A very risky and reckless policy with the Italic War still in the balance.

The kings, Nicomedes in particular, had taken out big loans at Rome to bribe the Senators to vote for their restoration (this decision was a given in accordance with long-term policy in the region, but it appears that by now nothing much was done by the Senate in foreign affairs without accompanying payments from the foreigners with something to gain by Roman intervention). Aquillius' retinue included representatives of the lenders. With Aquillius' support they now urged the two kings to invade the Pontic kingdom to secure the booty with which to repay the bribery loans.^[4] Fearing the power of Mithridates (and probably aware that the Senate had given no such orders), both kings demurred. But Nicomedes' creditors persisted with their pressure until he at last consented.

It was probably at the end of autumn 90 that Nicomedes regained control of the Thracian Bosporos and in the new sailing season (from mid March 89 BC) he prevented egress from the Euxine to Pontic ships.^[5]

Around the middle of spring 89 Nicomedes invaded the ancient Mithridateian dynastic lands of Mariandynia, plundering as far east as Amastris without encountering resistance. Mithridates had long been preparing a challenge to Roman power and the time was now ripe. As a final means of enlisting as much sympathy as possible in Anatolia, he offered no opposition to the Bithynian raid, preferring to appear as manifestly wronged by the puppets and representatives of Rome.^[6] The Bithyni returned home with a great deal of plunder^[7] - presumably sufficient for Nicomedes to repay his debts.

After the raid Mithridates sent his spokesman Pelopidas to the Roman legates and commanders to make complaint, apparently at Pergamon.^[8] At the same time Mithridates continued with his war preparations, trusting especially in his existing alliance with Tigranes of Armenia, although the more distant connection with Parthia was now without use because his ally Mithridates II had been slain by his rival Sanatruk attacking from the east in summer 91 BC, and a serious internal war persisted between Sanatruk and Mithridates' eldest son and heir Gotarzes I. Eventually the Parthian internal conflict was to seize the entire attention of Tigranes too, but this could not yet be known. The Pontic king was also exploiting carefully prepared networks of support and recruitment among the Thracians and the Scythians, and now solicited help and alliance from the kings in Syria and from Ptolemy Alexander I and the Cretans.^[9]

The Pontic envoy Pelopidas cleverly ignored the fact that Aquillius and his suite had induced the Bithynian raid. Instead he made propaganda about Roman intolerance towards Mithridates and concluded by appealing to the Treaty between Mithridates and Rome, calling upon the Romans, as friends and allies, to punish or restrain the Bithynian aggressor.^[10] Bithynian envoys replied first, citing Pontic aggression against Bithynia and her present king, the ominous Pontic buildup of arms, territory and resources, and alliances - from Armenia to Thrace while negotiations were still in progress with the Ptolemaic Empire and Seleucid Empire. Such vast preparations, the Bithyni insisted, were aimed not at Bithynia but at Rome herself.^[11] Pelopidas countered by agreeing to let bygones be bygones, and accepting all Roman acta in the East hitherto. But he insisted that something must be done about the most recent Bithynian acts of aggression: the closing of the Euxine and the invasion and plunder of Pontic territory. He once again called upon the Romans to honour the letter of the Treaty and help Mithridates punish his attackers, or at least its spirit and to stand aside while Mithridates himself took his revenge.^[12]

Through Pelopidas' skill in presenting the case, Mithridates' attempt to embarrass and even discredit the Roman representatives succeeded. The latter had made a show of listening fairly to both sides and were now embarrassed by the obvious injustice done to a nominal friend and ally. After a lengthy delay they finally came up with a publicly acceptable pronouncement: we do not wish harm done to our ally Mithridates, nor can we allow war to be made against Nicomedes because it is against the interests of Rome that he be weakened. Assembly dismissed. Pelopidas wished to make something of the insufficiency of this answer, but was ushered out.^[13]

Pontic re-occupation of Cappadocia, summer 89 BC

Mithridates knew enough about the workings of Roman politics to seek redress from the Senate, were he really interested. Instead he wanted to act under the éclat of the recent violation of his territory. After Pelopidas' return he sent his son Ariarathes into Cappadocia with a strong army. The occupation (summer 89 BC) was rapid and once again (now for a fourth time) Ariobarzanes I the philoromaios was expelled and the rule of Mithridates' son enforced.^[14] This violated both of the Senatus consultum authorising Aquillius' mission, and the Treaty. It was a strategic move with a view to serious conflict with the Romans: unlike Nicomedes, Ariobarzanes had done naught to offend. It was thus a de facto declaration of war.

The main ancient source, Appian, now states that both sides began to assemble large forces for all-out war,^[15] and implies precipitate action by the Pontic King. Instead a Pontic delegation was sent to Rome, and the marshalling of the armies in Anatolia must have taken up the remainder of the year. The Pontic embassy dates to the autumn and early winter 89 BC.

The details of the beginning of the war show that the precipitate action was taken by Aquillius himself, who was clearly keen to begin the war before the Pontic legation returned (even though its chances of success were slim following the reoccupation of Cappadocia, the possibility remained, in the context of the disastrous Italic War losses, that the Senate might prefer to negotiate a settlement and send a new legation to replace the provocative Aquillius). Marian instructions to Aquillius had probably been to precipitate war and thus present the Senate with a fait accompli. But the present situation was even better from Marius' viewpoint, since the war was now inevitable but still impending: which gave him time to get out to Asia province before it began, if he hurried. The election of Sulla as consul came as a shock (autumn 89, probably calendar December), and cannot have been foreseen.

News of Mithridates' second expulsion of Ariobarzanes (c. July 89) must have reached Rome in September, a month or two before Sulla was elected consul with Pompeius Rufus, for Plutarch records at the time of his entry into office:

Sulla regarded his consulate as a very minor matter compared with future events. What fired his imagination was the thought of the war against Mithridates. Here, however, he found himself opposed by Marius.^[16]

Clearly the prevalent view at Rome was that the reoccupation of Cappadocia was the last straw and that the Pontic king should be attacked and deposed. Even more importantly, the winding-down of the Italic War now released the troops necessary to effect this. Sulla's consulate came as something of a surprise. He had put himself back in the public eye by a good showing as a commander in the Italic War, and his election to the supreme executive seems to have been stitched up at the last minute in late autumn 89 by his marriage to Metella Delmatici filia, widow of the recently deceased princeps senatus M. Aemilius Scaurus, cousin of the praetor Metellus Pius and the young Luculli brothers. This brought him the whole weight of the extensive Metellan influence at the elections, while he was already close to his colleague Pompeius Rufus whose son was already married, with at least one child, to his daughter Cornelia. The men Sulla defeated apparently included another ambitious patrician vir militaris, L. Cornelius Cinna.

Pontic seizure of Roman Asia & Cilicia

Massacre of the Romans & Italici in Asia, c.May 88 BC

In Bithynia Mithridates received a radical and strange piece of advice from a prominent Greek philosopher at his court, Metrodoros of Skepsis, who was known as ho misoromaios (the Roman-hater) on account of the extremity of his anti-Roman sentiments. Metrodoros suggested that in order to bind the communities of the Roman province to the Pontic cause the king should arrange for the extermination of all Romans in the province without regard to age or sex and force the participation of all the Greek civic authorities, thus shaking off Roman rule permanently and irrevocably.

Soon after securing control of the province in about early April Mithridates proceeded with his plans. The massacre was carefully planned and co-ordinated to take the victims by surprise, in every community and all at once. In writing to all the civic authorities of the province, detailing the measures to be taken, the king stipulated that the killings were to be carried out exactly one month after the date of his letter. The date in question is not recorded but fell around early May 88 BC.
What took place on that day profoundly affected Roman/Hellenistic relations. Appian states that 80,000 Romans and Italians were killed in these "Asiatic Vespers".

Mithridates vs Rome

At this point, Mithridates finished capturing Asia Minor and established a presence in Greece. Archelaus was sent to Greece, where he established Aristion as a tyrant in Athens.

The Romans quickly declared war. In 87 BC, Consul Lucius Cornelius Sulla, landed in Epirus (western Greece), and marched on Athens. The course of Sulla's expedition has been pieced together through inscriptions (see: Roman Command Structure during First Mithridatic War). Marching into Attica through Boeotia, Sulla found the immediate allegiance of most of its cities, foremost among them Thebes. Most of the Peloponnese would soon follow after a victory mentioned by Pausanias (1.20.5) and Memnon (22.11). Athens, nevertheless, remained loyal to Mithridates, despite a bitter siege throughout the winter of 87/6. Sulla captured Athens on March 1, 86 BC, but Archelaus evacuated Piraeus, and landed in Boeotia, where he was defeated at the Battle of Chaeronea - notably the same site where Philip II of Macedon and a young Alexander the Great defeated combined Athenian and Theban resistance 250 years earlier, securing Macedonian supremacy.

Sulla's siege of Athens, summer 87-early 86 BC

Sulla's army took Athens on the Kalends of March,^[17] in the consulate of Marius and Cinna, February 12 86 BC. The siege of Athens was a long and brutal campaign, Sulla's rough battle hardened legions, veterans of the Social War thoroughly besieged and stormed Athens. Athens had chosen the wrong side in this struggle, portrayed as a war of Greek freedom against Roman domination. Soon afterwards he captured Athens' harbor of Peiraieus, with its skyline of temples and structures built by various Hellenistic kings who sought to add prestige and honor themselves by establishing structures in the famous city. Sulla thoroughly looted and demolished this area, most of which was destroyed by fire including the famous work of architecture Philon's Arsenal.^[18]

C. Scribonius Curio the orator (later cos.76) was put in charge of the siege of the Akropolis in Athens, and it was "some time" before Aristion and his followers eventually surrendered, which was not until their water had run out.^[19] (Perhaps the late spring). Athens was punished severely, a show of vengeance that ensured Greece would remain docile during later civil wars and Mithridatic wars.

The Chaeroneia campaign

Even after Sulla seized Peiraieus, Archelaos persisted in exploiting his command of the sea lanes, holding position off Mounychia with his fleet and preventing any food or materiel reaching the city or the Roman army by sea.^[20]
By the early spring Archelaos' strategy was biting hard. Rocky Attica provided good security for operations against the large Pontic cavalry forces massed in Macedonia, but it was infertile and notoriously incapable even of fully supporting the population of the astu, let alone the large Roman army in addition, with no imports coming in by sea.^[21]

Early in the spring of 86 BC Taxiles concentrated most of his troops, sent word to Archelaos to join him in the Magnetic ports, and marched south from Macedonia into Thessaly. Archelaos rejected the suggestion. He was the senior officer and preferred to persist with his blockade of Attica. Thessaly was only held by a modest Roman observation force under the legatus L. Hortensius, elder brother of Q.Hortensius the orator. But despite his great energy and reputation as an experienced vir militaris, there was little Hortensius could do against the enormous disproportion of the forces descending upon him, other than gather together some Thessalian auxiliary units he had been commissioned to recruit, and fall back southwards.
In about April 86 BC, beginning to run short of supplies and increasingly anxious about L. Hortensius' safety, Sulla took the bold decision to quit Attica and march into the fertile plains of Boiotia to feed his army, but also expose it to the great cavalry strength of the Pontic army.^[22]
In Boiotia, Sulla met and defeated Archelaos in the Battle of Chaeronea (86 BC). This move gave Archelaos little choice but to sail northward and link up with Taxiles. After being defeated by Sulla in the Battle of Orchomenus, Greece was fully restored to Roman rule.

The Lucullan mission

Meanwhile, Sulla's officer Licinius Lucullus pro quaestore defeated a Mithridatic fleet off the island of Tenedos. The next year, in 85 BC, Archelaus had received sufficient reinforcements to again offer battle to Sulla, but was again defeated at Orchomenus.

By now, Rome had also sent a force under Valerius Flaccus, which landed in Asia, where many of the Greek cities were in rebellion against Mithridates. Flaccus was killed in a mutiny led by Flavius Fimbria. Fimbria was able to defeat Mithridates' army on the river Rhyndacus. Mithridates then met Sulla at Dardanus in 85 BC, and got terms, which left him his kingdom.

Realizing that he could not face Sulla, Fimbria fell on his sword. This left Sulla to settle Asia, which he did by imposing a huge indemnity and with five years of back taxes, thus leaving the Asian cities heavily in debt for a long time to come.
