After the first world war, the Triveni Sangh was formed by the Ahirs and the Kurmis. The 'Triveni Sangh' was a caste coalition and political party established in Shahabad District of Bihar in pre-independence India to voice the political solidarity of 'middle peasant castes' as well as to carve a space in democratic politics for the lower castes. The Triveni Sangh was formed in the year 1934 by the members of backward castes of Bihar, namely Yadavs, Ahirs, Koeri, and Kurmi. Its nomenclature was acquired from the confluence of three mighty rivers, i.e. the Ganga, Yamuna and the mythical Saraswati at Allahabad. The Sangh claimed of having a minimum of one million dues-paying members. Its establishment was countered by the formation of the Indian National Congress's backward class federation, which was established at the same time.
