Sri Narayana Guru was a prophet, sage and Hindu saint and also a social reformer of India. He was born in the family of Ezhavas, in a period when people from backward communities, like, the Ezhavas faced much social injustices in the caste-ridden Kerala society. Gurudevan, as he was fondly known to his followers, revolted against casteism and worked on propagating new values of freedom in spirituality and of social equality, thereby transforming the Kerala society and as such he is adored as a prophet. India as a whole may have produced its Gandhi, but Keralites are inclined to take more pride in their own great spiritual and social leader, the contemporary of Gandhi, the low-caste sage Sri Narayana Guru, with his tireless preaching of the doctrine of 'One Caste, One Religion, One God.' He preached for moral and religious universalism.
Mahadev Govind Ranade hailing from Mumbai, was one of the most ardent supporters of women's rights and liberation. Justice Mahadev Govind Ranade graduated from Elphinstone College in Mumbai and became a teacher and journalist. Like so many other young men of his generation, he questioned the customs and beliefs of his society. In 1869 Ranade joined the Widow Marriage Association, and in 1870 the Prarthana Samaj. At first, he and his colleagues were engaged in "intellectual protest against superficial dogmas untenable for a rational mind," but later they became more interested in social action. Ranade was a significant reformer who, in his own way, did much for the advancement of women from their repressive situation in nineteenth century India.
