Year 86 BC was a year of the pre-Julian Roman calendar. At the time it was known as the Year of the Consulship of Cinna and Marius/Flaccus. The denomination 86 BC for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.
Lucius Licinius Lucullus was a Roman general and statesman, closely connected with Lucius Cornelius Sulla. In culmination of over 20 years of almost continuous military and government service, he conquered the eastern kingdoms in the course of the Third Mithridatic War, exhibiting extraordinary generalship in diverse situations, most famously during the Siege of Cyzicus in 73–72 BC, and at the Battle of Tigranocerta in Armenian Arzanene in 69 BC. His command style received unusually favourable attention from ancient military experts, and his campaigns appear to have been studied as examples of skillful generalship.
The First Mithridatic War was a war challenging the Roman Republic's expanding empire and rule over the Greek world. In this conflict, the Kingdom of Pontus and many Greek cities rebelling against Roman rule were led by Mithridates VI of Pontus against Rome and the allied Kingdom of Bithynia. The war lasted five years and ended in a Roman victory, which forced Mithridates to abandon all of his conquests and return to Pontus. The conflict with Mithridates VI later resumed in two further Mithridatic Wars.
The Third Mithridatic War, the last and longest of the three Mithridatic Wars, was fought between Mithridates VI of Pontus and the Roman Republic. Both sides were joined by a great number of allies dragging the entire east of the Mediterranean and large parts of Asia into the war. The conflict ended in defeat for Mithridates; it ended the Pontic Kingdom and the Seleucid Empire, and also resulted in the Kingdom of Armenia becoming an allied client state of Rome.
Archelaus was a prominent Greek general who served under King Mithridates VI of Pontus in northern Anatolia and was also his favorite general.
The siege of Cyzicus took place in 73 BC between the armies of Mithridates VI of Pontus and the Roman-allied citizens of Cyzicus in Mysia and Roman Republican forces under Lucius Licinius Lucullus. It was in fact a siege and a counter-siege. It ended in a decisive Roman victory.
The Battle of Cabira was fought in 72 or 71 BC between forces of the Roman Republic under proconsul Lucius Licinius Lucullus and those of the Kingdom of Pontus under Mithridates the Great. It was a decisive Roman victory.
The Battle of the River Amnias was a battle fought in 89 BC between Mithradates VI of Pontus and Nicomedes IV of Bithynia during the First Mithridatic War. The forces of Pontus were commanded by Archelaus and Neoptolemus, while the Bithynians were led by King Nicomedes himself. Pontus was victorious. This battle and subsequent events would lead to the loss of Roman rule in the province of Asia for some years.
The Battle of Lemnos was fought on the island of Lemnos in 73 BC between a Roman fleet and a Mithridatic fleet; it was a decisive event during the Third Mithridatic War. The primary chroniclers of the battle are Appian, Cicero and Memnon, but there remain debates about the specifics in these different accounts.
Pontus was a kingdom of Iranian origin, which possibly may have been directly related to Darius the Great of the Achaemenid dynasty. The kingdom was proclaimed by Mithridates I in 281 BC and lasted until its conquest by the Roman Republic in 63 BC. The Kingdom of Pontus reached its largest extent under Mithridates VI the Great, who conquered Colchis, Cappadocia, Bithynia, the Greek colonies of the Tauric Chersonesos, and for a brief time the Roman province of Asia. After a long struggle with Rome in the Mithridatic Wars, Pontus was defeated. The western part of it was incorporated into the Roman Republic as the province Bithynia et Pontus; the eastern half survived as a client kingdom until 62 AD.
Marcus Marius was a quaestor of the Roman Republic in 76 BC and proquaestor under Quintus Sertorius's government in exile in Spain. Marius was sent by Sertorius to Mithradates of Pontus as an advisor and military commander in the Third Mithridatic War. He is named as or more likely confused with a Varius in Appian.
The Battle of Chalcedon was a land and naval battle between the Roman Republic and King Mithridates VI of Pontus near the city of Chalcedon in 74 BC. It was the first major clash of the Third Mithridatic War. The Roman forces were led by Marcus Aurelius Cotta, one of the consuls for 74 BC, while Mithridates had the overall command of the Pontic forces. The Mithridatic forces were victorious on both land and sea.
Neoptolemus was a distinguished general of King Mithridates VI of Pontus. He was the brother of Archelaus, another general of Mithridates VI and the paternal uncle of Archelaus’ sons: Archelaus and Diogenes.
The Battle of the Rhyndacus occurred in 73 BC between a Roman Republican force under the command of the proconsul Lucius Licinius Lucullus and a division of the army of Mithridates VI of Pontus as part of the Third Mithridatic War. The Romans were victorious.
Marcus Aurelius Cotta was a Roman politician and general who was consul in 74 BC. He was posted to Bithynia with a Roman fleet as part of the Third Mithridatic War. He was defeated by King Mithridates VI of Pontus. Rescued by his fellow consul he reduced the Pontic coast and captured the city of Heraclea after a two-year siege. Returning to Rome in 70 BC, Cotta was acclaimed for his victory. However, around 67 BC he was convicted of the misappropriation of war booty and expelled from the Senate, a signal mark of disgrace.
The siege of Athens and Piraeus was a siege of the First Mithridatic War that took place from Autumn of 87 BC to the Spring and Summer of 86 BC. The battle was fought between the forces of the Roman Republic, commanded by Lucius Cornelius Sulla Felix on the one hand, and the forces of the Kingdom of Pontus and the Athenian City-State on the other. The Greek Pontian forces were commanded by Aristion and Archelaus.
The Fimbrian or Valerian legions were two Roman legions which served and fought in all three wars against King Mithridates of Pontus, one of the Roman Republic's chief adversaries during the 80s, 70s and 60s BC. They became a body of long serving legionaries known for their fierce fighting reputation and also, more infamously, for mutiny and abandoning their commander. The legions take their name from the consul Lucius Valerius Flaccus, who first recruited them in 86 BC, and from his subordinate, Gaius Flavius Fimbria, who took command of the legions after inciting a mutiny and murdering Flaccus.
The siege of Rhodes took place in 88 BC between the people of Rhodes and Mithridates VI of Pontus' army. The Rhodian forces were led by an admiral called Demagoras and the proconsul of Asia, Lucius Cassius, with them. After the defeat of Rome in the Battle of Protopachium, Rome was forced to retreat from Asia and the only major independent power left in that province was Rhodes. Rhodes had previously been an ally to both Mithridates and Rome, but now it only preferred Rome.
The siege of Heraclea was a military investment of the city of Heraclea Pontica during the Third Mithridatic War. The siege was conducted by the Roman proconsul Marcus Aurelius Cotta and the legate Gaius Valerius Triarius. They were besieging the adherents of Mithridates of Pontus, who held the city for the Pontic king. Heraclea was located on the strategically important northern land route into the kingdom of Pontus and had been taken and garrisoned by Mithridates on his retreat from the Siege of Cyzicus. The 4,000-man strong Mithridatic garrisoned was commanded by Connacorex, one of the king's generals, and held out for almost two years. After taking Heraclea, the Romans plundered the city extensively.
Gaius Valerius Triarius was a First Century BC Roman politician and general, a member of the gens Valeria. During the Third Mithridatic War he served as a legate to Lucius Licinius Lucullus, the Roman commander in charge of the war effort against king Mithridates VI of Pontus. He played a pivotal role in the capture of Heraclea Pontica, but was later defeated by Mithridates at the Battle of Zela in 67 BC.
