Suraj Narain Singh (1908-1973) was the foremost revolutionary nationalist in Bihar for almost two decades, during a tumultuous phase of India's struggle for independence.
In the post-independence period he was an active presence in the political scene of Bihar, as an important leader of the Praja Socialist Party as well as a member of the Legislative Assembly.
Suraj Narain Singh was radical and modern in his outlook. He denounced the caste system as well as the exploitative tendencies in the established religions of the world. He believed in universal brotherhood and considered service to humanity to be the supreme religion. He disapproved the western system of education and advocated national education in its place. He also stood for the abolition of the zamindari system, consolidation of holdings and mechanized agriculture.
