Bosporan Kingdom

The Bosphoran Kingdom was a Roman Client Kingdom between 8 BCE-341 CE, which was also known as Chersonesus Taurica.
It consisted of the Crimean Peninsular and its capital city, also called Chersonesus Taurica, and included the Eastern Crimea on the other side of the Kerch Strait.

Mithridates VI of Pontus was briefly King of this Kingdom in 63 BCE, after which it came under Roman Influence.
Between 8 BCE-38 CE it was a Roman Client Kingdom under King Aspurgus, assisted by a Roman Army.
Between 63-68 CE it became part of the Roman Province of Moesia Inferior under Nero, who deposed King Cotys I.
In 69 CE Galba restored it as a Roman Client Kingdom which it continued to be until 341 CE.
After 341 CE the record is unknown. It may have fallen to the Huns and the Alans, or become a Client Kingdom of the Byzantine Empire.

The Bosporan Kingdom was one of the Routes on the Silk Road.
In the Ancient World, trade passed out of China, through Afghanistan, down the River Oxus into both the Aral Sea and the Caspian Sea.
The Volga discharges into the Caspian Sea. There is a short overland connection where the River Don passes close to the Volga.
The Don then flows through the Sea of Azov and into the Black Sea, past the Crimean Peninsular and its Port.
