Abstract : Human history is the witness of many battles that has been fought between man and animals for their struggle initially for the survival of the fittest gradually takes the shape of racism between black and white. Blacks were segregated and even legally discriminated against in the pre-Civil Rights America which further resulted in the much ashamed slavery system. And as the result of the apartheid, Gandhiji was forced to get down from the running train in South Africa under British raj. Further, this racism leads to casteism where the people of higher caste exploit the lower caste. Casteism mistreated the so-called dalits & harijans in medieval India.
