Introduction
Political parties have been the principal vehicle by which subordinated groups entered the Indian mainstream, converting numerical strength into office and office into recognition, though mobilisation and empowerment do not always coincide.

Body

1. The Congress system of accommodation: Rajni Kothari's model of one-party dominance worked by absorbing caste factions and vote banks. The KHAM combination in Gujarat in 1980, and the filling of seats reserved under Articles 330 and 332, brought Dalit and Adivasi legislators in through the party machine.
2. The socialist and Lohiaite lineage: Lohia's demand that backward groups take sixty of every hundred posts, and Karpoori Thakur's Bihar reservation formula of 1978, prepared the ground that the Mandal recommendations occupied in 1990.
3. Autonomous Dalit parties: From Ambedkar's Independent Labour Party and Scheduled Castes Federation to Kanshi Ram's BAMCEF and the Bahujan Samaj Party of 1984, which made Mayawati Chief Minister four times, in what Jaffrelot calls a silent revolution.
4. Regional and social justice parties: The Justice Party and the Dravidian movement produced Tamil Nadu's sixty-nine per cent reservation, protected through the Ninth Schedule; the Jharkhand Mukti Morcha secured a State for Adivasi assertion in 2000.
5. Competitive expansion of the field: The BJP's consolidation of non-dominant backward castes, the elevation of Draupadi Murmu in 2022, the 102nd Amendment giving the National Commission for Backward Classes constitutional status, and the unanimous passage of the women's reservation amendment in 2023.

Conclusion
Parties turned social numbers into political power, the central democratic achievement of the past half-century. Kanchan Chandra's caution stands: patronage often enriches a group's own elite, and descriptive presence still outruns substantive representation, most visibly for Muslims.
