Plato was a Greco-Bactrian king who reigned for a short time in southern Bactria or the Paropamisade during the mid 2nd century BCE. The style of Plato's coins suggests that he was a relative — most likely a brother since Plato is a middle-aged man on his coins — of Eucratides the Great, whose rise to power is dated to around 170-165 BCE.
Some of Plato's coins have inscriptions which may be possibly be interpreted as dates using the Indo-Greek era which started around 186 BCE. In that case Plato ruled around 140 BCE. This matches the dating given by numismatician Bopearachchi, who places Plato between 145-140 BCE, since his coins are not found in the ruins of Ai Khanoum, a Bactrian city which was destroyed during the reign of Eucratides.
