Satyashodhak Samaj (Truth-seeker's Society) was a social reform society founded by Jyotirao Phule in Pune, Maharashtra, on 24 September 1873.
It espoused a mission of education and increased social rights and political access for underprivileged groups, focused especially on women, Shudras, and Dalits, in Maharashtra.
Satya Shodhak Samaj refused to regard the Vedas as sacrosanct, opposed idol worship, denounced the Chaturvarnya System (the caste system), and rejected the need for a Brahman priestly class as educational and religious leaders.
The existence of God was replaced by Nirmik.
Deenbandhu was the name of the mouthpiece of the Satya Shodhak Samaj.
