Efforts by the Indian government to make Hindi the sole official language after 1965 were unacceptable to many non-Hindi Indian states, which wanted the continued use of English. The Dravida Munnetra Kazhagam (DMK), a descendant of Dravidar Kazhagam, led the opposition to Hindi. To allay their fears, Nehru enacted the Official Languages Act in 1963 to ensure the continuing use of English beyond 1965. The text of the Act did not satisfy the DMK and increased their scepticism that future administrations might not honour his assurances. The Congress government headed by Indira Gandhi eventually amended the Official Languages Act in 1967 to guarantee the indefinite use of Hindi and English as official languages. This effectively ensured the current "virtual indefinite policy of bilingualism" of the Indian Republic.
