Chanakya (Kautilya, Vishnu Gupta) was an Indian teacher, philosopher, and royal advisor who is considered as the pioneer of the field of economics and political science in India. He taught economics and political science at the ancient Takshashila University. He played an important role in the establishment of the Maurya Empire (first empire in archaeologically recorded history to rule most of the Indian subcontinent). Chanakya served as the chief advisor to both Chandragupta and his son Bindusara.
