Chakravarti Rajagopalachari BR, popularly known as Rajaji or C.R., also known as Mootharignar Rajaji, was an Indian statesman, writer, lawyer, and independence activist. Rajagopalachari was the last Governor-General of India, as when India became a republic in 1950 the office was abolished. He was also the only Indian-born Governor-General, as all previous holders of the post were British nationals. He also served as leader of the Indian National Congress, Premier of the Madras Presidency, Governor of West Bengal, Minister for Home Affairs of the Indian Union and Chief Minister of Madras state. Rajagopalachari founded the Swatantra Party and was one of the first recipients of India's highest civilian award, the Bharat Ratna. He vehemently opposed the use of nuclear weapons and was a proponent of world peace and disarmament. During his lifetime, he also acquired the nickname 'Mango of Salem'.

The Bharat Ratna is the highest civilian award of the Republic of India. Instituted on 2 January 1954, the award is conferred in recognition of "exceptional service/performance of the highest order", without distinction of race, occupation, position or gender. The award was originally limited to achievements in the arts, literature, science, and public services, but the Government of India expanded the criteria to include "any field of human endeavor" in December 2011. The recommendations for the award are made by the Prime Minister to the President. The recipients receive a Sanad (certificate) signed by the President and a peepal leaf-shaped medallion with no monetary grant associated with the award. Bharat Ratna recipients rank seventh in the Indian order of precedence.
