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 256 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.
