Jagjivan Ram, Indian politician, 4th Deputy Prime Minister of India (d. 1986)
Jagjivan Ram (5 April 1908 – 6 July 1986), known popularly as Babuji, was an Indian independence activist and politician from Bihar. He was instrumental in the foundation of the All India Depressed Classes League, an organisation dedicated to attaining equality for untouchables, in 1935 and was elected to Bihar Legislative Assembly in 1937, after which he organised the rural labour movement.

In 1946, he became the youngest minister in Jawaharlal Nehru's interim government, the first cabinet of India as a Labour Minister and also a member of the Constituent Assembly of India, where he ensured that social justice was enshrined in the Constitution. He went on to serve as a minister with various portfolios for the next 30 years as a member of the Indian National Congress (INC). Most importantly, he was the Defence Minister of India during the Indo-Pak war of 1971, which resulted in the creation of Bangladesh. His contribution to the Green Revolution in India and modernising Indian agriculture, during his two tenures as Union Agriculture Minister are still remembered, especially during the 1974 drought when he was asked to hold the additional portfolio to tide over the food crisis.Though he supported Prime Minister Indira Gandhi during the Emergency (1975–77), he left Congress in 1977 and joined the Janata Party alliance, along with his Congress for Democracy. He later served as the Deputy Prime Minister of India (1977–79); then in 1981, he formed Congress (J). At his death, he was the last surviving minister of the Interim Government and the last surviving original member of the first cabinet of independent India. Including his service during the Interim Government, his total tenure of over 30 years in various ministries remains the longest of any Indian federal minister.
