Maurya Period

The Maurya Empire (322–185 B.C), ruled by the Mauryan dynasty, was geographically extensive, powerful, and a political military empire in ancient India. The great Maurya empire was established by Chandragupta Maurya and this empire was flourished by Ashoka the Great. 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. The Empire was expanded into India's central and southern regions by the emperors Chandragupta and Bindusara, but it excluded a big portion of unexplored tribal and forested regions near Kalinga which was won by Ashoka the Great. Ashoka propagated Buddhism across the world and established many Buddhist monuments.
Chandragupta's minister Chanakya wrote the Arthashastra, one of the greatest treatises on economics, politics, foreign affairs, administration, military arts, war, and religion produced in Asia. Archaeologically, the period of Mauryan rule in South Asia falls into the era of Northern Black Polished Ware (NBPW). The Arthashastra and the Edicts of Ashoka are primary sources of written records of the Mauryan times. The Lion Capital of Asoka at Sarnath, is the national emblem of India.
