Eucratides I is one of the most important Greco-Bactrian kings. Eucratides overthrew the Euthydemid dynasty and restored the Diodotids to power. He fought against the easternmost Hellenistic and Indian rulers in India, holding territory in the Indus and as far as Barigaza until he was finally defeated by Menander and pushed back to Bactria. Eucratides minted a vast and prestigious coinage, suggesting a rule of considerable importance and prosperity.
