The Arthashastra is an insight into the political thoughts of Kautilya. The book was written around 250 BCE. The most interesting idea presented in the book is the Mandala theory of interstate relations. Mandala represents the universe and our own kingdom is in the centre of a circular Mandala. The area surrounding the Mandala should be considered territories belonging to our enemies. The circle surrounding our enemies’ territories will be the allies of our enemies.
