Eucratides I Eucratides I, sometimes called Eucratides the Great, was one of the most important Greco-Bactrian kings, descendants of dignitaries of Alexander the Great. He uprooted the Euthydemid dynasty of Greco-Bactrian kings and replaced it with his own lineage. He fought against the Indo-Greek kings, the easternmost Hellenistic rulers in northwestern India, temporarily holding territory as far as the Indus, until he was finally defeated and pushed back to Bactria. Eucratides had a vast and prestigious coinage, suggesting a rule of considerable importance. Demetrius II of India Demetrius II was a Greco-Bactrian/Indo-Greek king who ruled briefly during the 2nd century BC. Little is known about him and there are different views about how to date him. Earlier authors such as Tarn and Narain saw him as a son and sub-king of Demetrius I, but this view has now been abandoned. Demetrius III Aniketos Demetrius III Aniketos is an Indo-Greek king who reigned in the area of Gandhara and Punjab. Greco-Bactrian Kingdom The Greco-Bactrian Kingdom was, along with the Indo-Greek Kingdom, the easternmost part of the Hellenistic world, covering Bactria and Sogdiana in Central Asia from 250 to 125 BC. It was centered on the north of present-day Afghanistan. The expansion of the Greco-Bactrians into present-day eastern Afghanistan and Pakistan from 180 BC established the Indo-Greek Kingdom, which was to last until around AD 10.
