Samyukta Vidhayak Dal
Samyukta Vidhayak Dal was coalition of parties formed in several north Indian states after the 1967 assembly elections. It was made up of the Bharatiya Kranti Dal, the Samyukta Socialist Party, the Praja Socialist Party, the Jana Sangh. This coalition opposed the Indian National Congress party that had hitherto single-handedly dominated Indian politics.
The 1967 Indian general election was a landmark election in the history of India. The ruling Congress party returned to power with the lowest majority it had since independence. It was defeated in assemblies like Bihar, U.P., Rajasthan, Punjab, West Bengal, Orissa, Madras, and Kerala. This was first big transition in India. In many states in the north, where it had won narrow victories, its members defected to opposition parties. Consequently, the Congress governments fell and they were replaced by Samyukta Vidhayak Dal governments. This was coalition of legislators against the Congress - made up Jana Sangh, Socialists, Swantantra Party, And Congress defectors, beside local parties.
