The Maurya Empire was a geographically extensive and powerful empire in ancient India, ruled by the Mauryan dynasty from 321 to 185 BC. Originating from the kingdom of Magadha in the Indo-Gangetic plains in the eastern side of the Indian subcontinent, the empire had its capital city at Pataliputra. The Empire was founded in 322 BC by Chandragupta Maurya, who had overthrown the Nanda Dynasty and rapidly expanded his power westwards across central and western India taking advantage of the disruptions of local powers in the wake of the withdrawal westward by Alexander the Great''s Greek and Persian armies. By 320 BC the empire had fully occupied Northwestern India, defeating and conquering the satraps left by Alexander. It was the world''s largest empire in its time. At its greatest extent, the empire stretched to the north along the natural boundaries of the Himalayas, and to the east stretching into what is now Assam. To the west, it reached beyond modern Pakistan, annexing Balochistan and much of what is now Afghanistan, including the modern Herat and Kandahar provinces.
