He took a prominent part in Panchayat organisations, local Board administration. He served as the President of Rajapalayam Union, the Panchayat court, the District Board of Ramnathapuram and the District educational Council among others.
The lives and writings of Annie Besant and Satyamurthy had great influence on his mind and character in his formative years. It was in 1919 that he met Mahatma Gandhifor the first time and started following with great interest the events in Gandhi's life. Gandhi's epic struggle in South Africa, the founding of the Ashram in Ahmedabad and the Champaran struggle made a profound impression on him and the utter simplicity of Mahatma's life also evoked his unbounded admiration. In 1932, he was arrested for disobeying the unjust laws. Thus Rajapalayam gained a distinct place in political map, the credit went to Raja's lead. In 1934, Raja won central legislature for constituency comprising Tirunelveli, Madurai & Ramanathapuram. At the age of 39, he entered the Assembly as M.L.A in C. Rajagopalachari ministry successfully contesting the 1937 election. He was the Chief Minister of Tamil Nadu from 1949 to 1950 and Governor of Orissa from 1954 to 1956. In all the years of his life, most of Raja's wealth was spent in helping the poor and in serving public causes, particularly for the Congress movement. He was much interested in co-operative movement also. He founded Bhupathi Raju Cop-operative Credit Bank, an urban bank for the benefit of local people especially farmers named after his friend, Bhupathi Raju of Andhra Pradesh, who accompanied him in prison during freedom movement. He constructed the monument Congress Ponvizha Grounds in Rajapalayam commemorating the Jallianwala Bagh massacre during the freedom struggle. Raja's life was one of noble activity, dedication and selfless servicefor the people of the country. He was a staunch proponent of the concept of "Separation of the Judiciary from the Executive". Prohibition, promotion of Khādī and Temple entry legislation were his other notable achievements. He donated his house for starting an institution of culture called "Gandhi Kalai Mandram". Rajapalayam became a great industrial centre mainly due to his drive and interest. It was said that Raja studied in Srivilliputtur G.S Hindu higher secondary school and thus he chose his temple as the symbol of Tamil Nadu emblem'. And his successor Rajagopalachari might not have minded that the shrine of Andal was now the Madras government's symbol. Raja died on 16 March 1957 in Madras, upon not recovering from an illness following his return from a visit to his ancestral village in Andhra Pradesh.
