The Swatantra Party was an Indian classical liberal political party that existed from 1959 to 1974. It was founded by C. Rajagopalachari in reaction to what he felt was the Jawaharlal Nehru-dominated Indian National Congress's increasingly socialist and statist outlook.

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'.
