Explanation:
The Maurya Empire was the first unified great empire of India. Ruled by the Maurya dynasty, it lasted from 320 a. C. to 185 a. C. (probable dates), dominating all the north and center of India and some regions of Afghanistan and Pakistan.
Originating from the kingdom of Magadha in the plains of the Indo-Ganges basin in the modern city of Bihar and Bengal, with its capital Pataliputra (near modern Patna), the Empire was founded in 321 BC. C. by Chandragupta Maurya, who had overthrown the Nanda Dynasty and begun to expand its power through central and western India.
The empire was expanded to the north, along the natural borders of the Himalayas, and east to the present state of Assam. To the west, it reached beyond Pakistan and included Baluchistan in Persia and significant parts of now Afghanistan, including Herat and the Kandahar provinces. The Empire was extended in the central regions and towards the south of India by the emperor Bindusara, but this excluded a small part of the unexplored regions near Kalinga.
