Mahatma Jyotirao Phule, a social reformer and activist from Maharashtra, founded the Satya Shodhak Samaj (Society of Truth Seekers) in 1873. The aim of this organization was to promote social equality and challenge the dominance of the upper castes, particularly the Brahmins, in the social hierarchy of India. Phule worked for the upliftment of the oppressed castes and advocated for education, especially for women and lower-caste individuals. The Satya Shodhak Samaj played a crucial role in the fight against caste discrimination and the emancipation of marginalized sections of Indian society.
