Diodotus II Theos (Greek: Διόδοτος Θεός, Diódotos Theós; died c. 225 BC) was the son and successor of Diodotus I Soter, who rebelled against the Seleucid empire, establishing the Graeco-Bactrian Kingdom. Diodotus II probably ruled alongside his father as co-regent, before succeeding him as sole king around 235 BC. He prevented Seleucid efforts to reincorporate Bactria back into the empire, by allying with the Parthians against them. He was murdered around 225 BC by Euthydemus I, who succeeded him as king.
Diodotus’ career was recounted by Apollodorus of Artemita in the Parthian History, but this text is lost, and surviving literary sources only mention him in passing.[1] Thus, most details of Diodotus' life and career have to be reconstructed from numismatics.
