This book, published by Cambridge University Press, challenges the view, common among Western scholars, that precolonial India lacked a tradition of military philosophy. It traces the evolution of theories of warfare in India from the dawn of civilization, focusing on the debate between Dharmayuddha (Just War) and Kutayuddha (Unjust War) within Hindu philosophy.
