Demetrius II
However, Demetrius III is the only Demetrius to strike bilingual Greek/Indian (Kharoshti) coins, and is therefore a likely candidate to be identified with the "Demetrius, king of the Indians" mentioned by Roman historian Justin. This Demetrius is said to have fought with the Bactrian king Eucratides (c. 170–145 BCE) during the latter part of Eucratides' rule. Bopearachchi nevertheless identifies Justin's Demetrius with the king Demetrius II even though he only struck Greek coins and reigned c. 175–170 BCE, even before Eucratides. In addition, Bopearachchi's early dating of Demetrius II has been challenged (see discussion under Demetrius II).
