Input (English): The Greeks Megasthenes and Deimachus were sent as ambassadors to the first and second rulers of this polity. Demetrius I of Bactria began his devastating invasion of this empire after a coup overthrew their last ruler; his new empire would share the region with the Sunga Empire founded by the leader of that coup. The first ruler of this empire was advised by the author of a treatise on statecraft called the Arthashastra, Chanakya. That ruler consolidated his power by defeating Magadha, and he left a vast empire to his son Bindusara. This empire's third ruler was so sickened by his expansive military conquests that he built thousands of stupas and famously converted to Buddhism. For 10 points, name this Indian empire founded by Chandragupta and later ruled by Asoka.
