The 1967 election marked a landmark in the history of India. It brought a series of changes to the political system were:
i) The Congress party suffered its worst defeat till then. Although it came to power, with the lowest majority, it had since independence. Its vote share decreased, and there was a gradual loss of mass support
ii) The Congress lost in as many as 8 state assemblies (Bihar, U.P., Rajasthan, Punjab, West Bengal, Orissa, Madras, and Kerela). Thus, its dominance declined.
iii) This was the first big transition in India as the party which ruled for two decades was now challenged.
iv) There was a rise in regional parties. In the southern states such as Kerela and Tamil Nadu, DMK emerged victoriously. This made the political system more competitive.
v) For the first time in political history, the coalition was formed against the Congress. Samyukta Vidhayak Dal- which comprised of Jan Sangh, socialists, Swatantra and congress defectors, formed a government in the state.
vi) Thus, a full-fledged democracy took roots in India and the country move towards a competitive multi-party system.
