The Indian National Congress was founded only before December 1884.
In 1969, the party suffered a major split, with a faction led by Indira Gandhi leaving to form the Congress (R), with the remainder becoming the Congress (O)
 The party's first Prime Minister, Pandit Jawaharlal Nehru, led the Congress to support socialist policies by creating the Planning Commission, introducing Five-Year Plans, implementing a mixed economy, and establishing a secular state
