The Bosporan Kingdom was located between the Crimean and Taman peninsulas centered around the Kerch Strait, known in antiquity as the Cimmerian Bosporus, from where the kingdom's name is derived. It was briefly incorporated as part of the Roman province of Moesia Inferior from 63 to 68 AD under Emperor Nero, before being restored as a Roman client kingdom.

Rheskuporis V, was the king of the Bosporan Kingdom, a Roman client state, from 240 to 276. The reign of Rhescuporis V overlaps with those of several other Bosporan kings; Pharsanzes (253–254), Sauromates IV (276) and Teiranes (276–278). It is unclear what their relationships and status were relative to each other and if they were co-rulers or rival contenders for the throne.
