Arthashastra by Kautilya

Arthashastra is arguably the greatest treatise ever written on political, military, and economic strategies, by a shrewd man popularly referred to as the Indian Machiavelli.
One of the most ancient and enduring works on statecraft and governance, Arthashastra is still widely read and studied today. Serving as the handbook for rulers, it answers a plethora of questions.
What are the qualities of an able king?
What does it take to manage a kingdom?
How can one expand one’s territory?
And to hold one’s power and gain wealth for one’s subjects, how far can a king go?"
