Raja Bahadur Kamakhya Narain Singh of Ramgarh, Jharkhand entered politics in 1946 following the formal accession of the Ramgarh state into the Indian Republic. In the Bihar Assembly Elections of 1967, serious opposition was offered by the Raja Bahadur's Swatantra Party to the ruling Congress government. The Raja Bahadur and his younger brother, Dr. Basant Narayan Singh, became Cabinet Ministers in the government headed by Chief Minister of Bihar Sri Mahamaya Prasad Sinha. He resigned from the party because he was not made the Deputy Chief Minister. In late 60s, Kamakhya Narayan Singh was popularly an aspirant for Rajput supremacy in Bihar against Rajput stalwart Sri Satendra Narain Singh(then known as "Coming Chief Minister of Bihar") but was out manoeuvred. His party later merged with the Janata party. Many of his family members became important political functionaries and legislators.
