Social reform movements in India aimed to gradually reform society and attack social evils like bigotry, superstition, and the hold of priestly classes. Key movements focused on women's reform like abolishing sati and promoting widow remarriage and women's education. Other efforts targeted the abolition of slavery, child marriage, and reform for Dalits and peasants. Important leaders included Ram Mohan Roy, Swami Dayanand Saraswati, Jotirao Phule, Ishwar Chandra Vidyasagar, and B.R. Ambedkar who advocated for women's rights, ending untouchability, and separate electoral systems for Dalits.
