Tiberius Julius Cotys I
Tiberius Julius Cotys I Philocaesar Philoromaios Eusebes, also known as Cotys I or Kotys I (Greek: Τιβέριος Ἰούλιος Κότυς Α' Φιλόκαισαρ Φιλορωμαῖος Eὐσεβής, Philocaesar Philoromaios Eusebes, means lover of Caesar, lover of Rome who is the Pius one, flourished 1st century) was a prince and Roman Client King of the Bosporan Kingdom.
Cotys I was the second son of Roman Client Monarchs Aspurgus and Gepaepyris. His eldest brother was prince and King Mithridates. He was a prince of Greek, Iranian and Roman ancestry. Cotys I was the second grandchild and grandson of Bosporan Monarchs Asander and Dynamis and Roman Client Rulers of Thrace, Cotys VIII and Antonia Tryphaena.
Through his maternal grandmother Antonia Tryphaena, he was a descendant of Roman triumvir Mark Antony. Tryphaena was the first great granddaughter born to the triumvir. Through Tryphaena, Cotys I was also related to various members of the Julio-Claudian dynasty. Through Aspurgus, Cotys I was a descendant of the Greek Macedonian Kings: Antigonus I Monophthalmus, Seleucus I Nicator and Regent, Antipater. These three men served under King Alexander the Great. Cotys I was named in honor of his late maternal grandfather, Roman Client Ruler of Thrace, Cotys VIII.
Little is known on the life of Cotys I. When Aspurgus died in 38, his brother had become joint rulers with his mother. Sometime before 45, the Roman Emperor Claudius, had given his brother the whole Bosporan Kingdom to rule. Claudius recognised and appointed Mithridates as the legitimate Bosporan King. In 45 for unknown reasons Claudius, deposed Mithridates from the Bosporan throne and Claudius replaced Mithridates with him. Claudius had withdrawn the Roman garrison under Aulus Didius Gallus from the Bosporan Kingdom and a few Roman cohorts were left with the Roman Knight Gaius Julius Aquila in the Bosporan.
Cotys I’s brother despised the situation and mistrusted him and Aquila. Mithridates attempted to regain his throne. Mithridates was able to entice the leaders of the local tribes and deserters into his allies. He was able to seize control of the local tribes and collect an army to declare war on Cotys I and Aquila.
When Cotys I and Aquila heard news of this war, they feared that the invasion was imminent. Both men knew they had the support of Claudius. Mithridates with his army, engaged in war with Cotys I’s army and Aquila’s battalions, in a three-day war, which Cotys I and Aquila won unscathed and triumphant at the Don River.
Mithridates was forced by Claudius to surrender. Mithridates was captured and taken to Rome as a prisoner. He was displayed as a public figure beside the platform in the Roman Forum along with his guards and his expression remained undoubted. Mithridates appealed to the Emperor for mercy to be spared from a triumphal procession or capital punishment. Claudius was impressed with Mithridates’ mercy from his letter and allowed Mithridates to live. He was spared from any capital punishment and was exiled. Cotys I’s brother lived as a destitute exiled monarch until his death.
From 45 until 63, Cotys I reigned as Roman Client King of the Bosporan Kingdom. Sometime during his reign, Cotys I had married a Greek noblewoman called Eunice, through whom had a son called Tiberius Julius Rhescuporis I. Cotys I named his son, after Rhescuporis II, a Thracian prince and king, who was a paternal uncle of his maternal grandfather.
In 63 for unknown reasons, the Roman Emperor Nero disposed Cotys I from his throne. Perhaps Nero wanted to minimise the role, power and influence of local client rulers and desired the Bosporan Kingdom to be completely governed by the Roman state. His fate afterwards is unknown. The Bosporan Kingdom was incorporated as a part of the Roman Province of Moesia Inferior from 63-68. In 68, the new Roman Emperor Galba had restored the Bosporan Kingdom to Rhescuporis I. Rhescuporis I reign from 68 until at least 90. Rhescuporis I was a contemporary of the ruling Flavian dynasty, in particular the reign of Domitian. Through Rhescuporis I, Cotys I would have various descendants ruling on the Bosporan throne until the mid-4th century and among his descendants would have at least two kings, who bore his name.
