The Maurya Empire was founded by Chandragupta Maurya, with help from Chanakya, at Takshashila.
The Greek generals Eudemus, and Peithon, ruled until around 317 BCE, when Chandragupta Maurya (with the help of Chanakya, who was now his advisor) utterly defeated the Macedonians and consolidated the region under the control of his new seat of power in Magadha [REF].
