Kautilya’s Arthaśāstra, written around 300 BC, is a text on statecraft, a book of political realism. It deals with various topics including war and diplomacy, how a king can retain his kingdom and become a conqueror, how to make allies and know the enemies, and how to make treaties. It focuses on elements, what can be termed in modern usage diplomacy, such as the doctrine of a silent war, propaganda, secret agents, how to use women as weapons of war, and how to use religion and superstition to advantage. According to Kautilya, “power is (possession of) strength” and “strength changes the mind.” More importantly, Kautilya emphasized power to control not only outward behavior but also the thoughts of one’s subjects and enemies. According to him, “one possessed of personal qualities, though ruling over a small territory … conversant with (the science of) politics, does conquer the entire earth, never loses.” Kautilya is the founder of Mandala Theory of foreign policy, which can be termed as a precursor of the theories of political realism and balance of power. Kautilya favored righteous war than greedy and demoniacal wars.
