Kautilya was an Indian philosopher who authored the Arthashastra, an ancient treatise on governance, economics, and political administration. The Arthashastra provides guidance for rulers on topics such as foreign policy, administration, finance, and social welfare. Many of Kautilya's principles of stable governance, responsive officials, infrastructure development, and linking economic objectives to people's welfare remain relevant today. His work had a significant influence on rulers and statesmen in ancient and modern South Asia.
