Jotirao Govindrao Phule was born in Satara district of Maharastra in a family belonging to Mali (Fulmali) caste, a kshatriya caste. His father, Govindrao, was a vegetable vendor. Originally Jotirao's family, known as Gorhays, came from Katgun, a village in Taluka- Khatav, District- Satara. His grandfather Shetiba Gorhay settled down in Pune. Since Jotirao's father and two uncles served as florists under the last of the Peshwas, they came to be known as 'Phules'. (Reference- P.G. Patil, Collected Works of Mahatma Jotirao Phule, Vol-II, published by Education department, Govt. of Maharashtra). His mother died when he was 9 months old.
The main objectives of the organisation were to liberate the Shudras and Ati Shudras and to prevent their 'exploitation' by the upper caste like Brahmans. Through this Satya Shodhak Samaj, Jotirao refused to regard the Vedas as sacrosanct. He opposed idolatry and denounced the chaturvarnya system (the caste system). Satya Shodhak Samaj propounded the spread of rational thinking and rejected the need for a Brahman priestly class as educational and religious leaders. He was an aboriginal of India and established Satyadharma and never renounced his faith. He was against those Brahmins who were using religion and blind faith of masses for their own monetary gains. But Jyotiba had many Brahmin personal friends and he even adopted a Brahmin boy as his heir. He made a will giving his large property after his death to this Brahmin boy.
