In the 1951 election, three ethnic parties challenged the Congress party: the Ram Rajya Parishad, the Hindu Mahasabha, and the Bharatiya Jana Sangh. These three sought to gain support from the Hindu majority. The All India Scheduled Caste Federation bid for support from the ex-untouchable castes. Three of the four ethnic parties gradually disappeared because they were not able to obtain enough votes. In the late 1980s, the Congress began to decline. More non-congress parties started to challenge the Congress dominance. The Bharatiya Janata Party (BJP) descended from the Bharatiya Jana Sangh. It attempted to pit Hindus against Muslims. The Bahujan Samaj Party (BSP) and the Janata Dal ( JD) tried to seek support from the Scheduled Castes, and Muslims against the upper castes.
