Born to a family of low status in the Roman province of Dalmatia, Diocletian rose through the ranks of the military to become cavalry commander to the Emperor Carus. After the deaths of Carus and his son Numerian on campaign in Persia, Diocletian was proclaimed emperor. The title was also claimed by Carus' other surviving son, Carinus, but Diocletian defeated him in the Battle of the Margus.
Diocletian's reign stabilized the empire and marks the end of the Crisis of the Third Century. He appointed fellow officer Maximian as Augustus, co-emperor, in 286.
He reigned twenty-one years and then abdicated voluntarily. He lived out his retirement in his palace on the Dalmatian coast, tending to his vegetable gardens.

A very unusual style of bust on this wonderful medallic coin from the London mint. After consulting with Lee Toone i'm going with CT 2.01.003 (8), but there are so many subtle variations in style during this period. "A fine example of this coarser style probably engraved by an Allectan engraver learning how to adapt to the larger canvas of the new (for Britannia) nummi" (Lee Toone - 20.07.20). Ex. Brian Henry Grover Collection (Roma Numismatics E-Sale 72; Lot 1394)
