Arthashastra

In 1904, a copy of an ancient book which had been lost for more than 1400 years was discovered in India. A modest book written on palm leaves, its outward appearance was proven to be deceiving as the book contained surprisingly detailed information on how an effective government should be run, treating wide-ranging topics from war, diplomacy, law, taxation, agriculture, how to manage secret agents, when it is useful to violate treaties, even when to kill family members.
