Tiberius Julius Rhescuporis VI

Reign The last known member of the Tiberian-Julian dynasty, His reign overlaps with the other Bosporan king Rhadamsades , The relationship between Rhescuporis VI and his immediate predecessors (and co-ruler in the case of Rhadamsades) is not outlined in any surviving source.

It has been pointed out, for instance by Astakhov (2021), that Rhadamsades and Theothorses are Iranian names and that these two kings might thus not have been genuine representatives of the Tiberian-Julian dynasty. The Iranian origin of the names and the Sarmatian sign on Theothorses's coins is not wholly convincing evidence since the Tiberian-Julian dynasty itself was of partly Sarmatian origin (Rhescuporis for instance being a name of Sarmatian origin) and tamgas were frequently used symbols in the kingdom.

The end of Rhescuporis VI's reign is generally connected by historians to the end of Bosporan coin production in 341, though there are no surviving sources to confirm this. Given that sources on the Bosporus from after 341 nearly non-existent, Rhescuporis VI is often referred to as the last king of the Bosporan Kingdom. By the time of Justinian I, the ruler of the Bosporan realm was the Hunnish king Gordas. Gordas converted to Christianity under Justinian's sponsorship at Constantinople in 527, but was killed in a revolt upon his return home owing to his attempts at forcible conversion of his supporters and the populace. After Gordas's death, a Roman army was sent to the Bosporus which quelled the uprising and established imperial control there.
