Social reformers played a vital role in shaping social reform movements by acting as leaders, thinkers, and activists. Figures such as Raja Ram Mohan Roy, Jyotirao Phule, and Swami Vivekananda challenged unjust customs and promoted equality, education, and human values. They used writings, speeches, and institutions to spread awareness among the masses. Their courage and vision inspired people to rethink social norms and work collectively for reform, leaving a lasting impact on Indian society.
