Gandhi struggled throughout his life against what he considered three great evils afflicting India. One was British rule, which Gandhi believed impoverished the Indian people by destroying their village-based cloth-making industry. The second evil was Hindu-Muslim disunity caused by years of religious hatred. The last evil was the Hindu tradition of classifying millions of Indians as a caste of " untouchables ". Untouchables, those Indians born into the lowest social class, faced severe discrimination and could only practice the lowest occupations.
