<P> Corruption therefore translated into power and a means to enter the political arena, once only open to upper caste members . In this way corruption was seen as a way to level the playing field, and as a result was tolerated and in some villages championed under the banner of "social justice". </P> <P> 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 . </P> <P> The intense party competitions that started in the late 1970s have also weakened the influence of caste in Indian politics . Traditionally, Indian political parties have been constructed from top - down . Party leaders relied on preexisted patron - client networks to collect votes . Hence, no parties established fixed organisations to keep constant contacts with the village - level . Since 1977, the number of youth participating in politics has significantly increased . Due to the lack of fixed organisations, political parties had to rely on the young village members for political mobilisation . Often, these young villagers exerted more political influence than the upper caste leaders and patrons . The status of these young people in the village depended on how much he could contribute to the economic development of the village . It is easier for the youth to maintain their status by rallying rather than remain loyal to a specific party . This also weakened the influence of caste and clientelism on Indian politics . </P> <P> In the 1990s, many parties Bahujan Samaj Party (BSP), the Samajwadi Party and the Janata Dal started claiming that they were representing the backward castes . Many such parties, relying primarily on Backward Classes' support, often in alliance with Dalits and Muslims, rose to power in Indian states . At the same time, many Dalit leaders and intellectuals started realising that the main Dalit oppressors were the so - called Other Backward Classes, and formed their own parties, such as the Indian Justice Party . The Congress (I) in Maharashtra long relied on OBCs' backing for its political success . Bharatiya Janata Party has also showcased its Dalit and OBC leaders to prove that it is not an upper - caste party . Bangaru Laxman, the former BJP president (2001--2002) was a former Dalit . Sanyasin Uma Bharati, former CM of Madhya Pradesh, who belongs to OBC caste, was a former BJP leader . In 2006 Arjun Singh cabinet minister for MHRD of the United Progressive Alliance (UPA) government was accused of playing caste politics when he introduced reservations for OBCs in educational institutions all around . </P>
