The Arthashastra

Arthashastra is an excellent treatise on statecraft, economic policy and military strategy. it is said to have been written by Kautilya, also known by the name Chanakya or Vishnugupta, the prime minister of India's first great emperor, Chandragupta Maurya.
Kautilya mixes the harsh pragmatism for which he is famed with compassion for the poor, for slaves, and for women. He reveals the imagination of a romancer in imagining all manner of scenarios which can hardly have been commonplace in real life.
