Chanakya

He vowed to dethrone the haughty king who was harassing the people of the land. After fulfilling that vow, he made Chandragupta the Emperor. He brought Amatya Rakshasa from the enemy camp to serve as Chandragupta's prime minister. His 'Arthashastra' is a classic of statecraft and is reverently studied even in Europe and elsewhere. Chanakya is the personification of statesmanship, political craft, spirit of adventure and unyielding perseverance.
