Buddhist Emperor Asoka built thousands of Stupas and Viharas for Buddhist followers. One of his stupas, the Great Sanchi Stupa, has been declared as a World Heritage Site by UNECSO. The Ashoka Pillar at Sarnath has a four-lion capital, which was later adopted as the national emblem of the modern Indian republic. Throughout his life, Asoka the Great followed the policy of nonviolence or ahimsa. Even the slaughter or mutilation of animals was abolished in his kingdom. He promoted the concept of vegetarianism. The caste system ceased to exist in his eyes and he treated all his subjects as equals. At the same time, each and every person was given the rights to freedom, tolerance, and equality.
