Ranade was a founder of the Social Conference movement, which he supported till his death, directing his social reform efforts against child marriage, the shaving of widows' heads, the heavy cost of marriages and other social functions, and the caste restrictions on traveling abroad, and he strenuously advocated widow remarriage and female education. He was one of the founders of the Widow Marriage Association in 1861. Though Ranade criticised superstitions and blind faith, he was conservative in his own life. He chose to take prayaschitta (religious penance) in case of Panch-houd Mission Case rather than taking a strong side of his opinions.
