Chanakya, also known as Kautilya or Vishnu Gupta, was an ancient Indian teacher, philosopher, and royal advisor. He played a crucial role in the establishment of the Maurya Empire under the leadership of Emperor Chandragupta Maurya. Chanakya's teachings and strategies on governance and politics are documented in his work "Arthashastra" and continue to be studied and revered to this day.
