“The Indian party system is shaped by a complex interaction of the country’s federal structure, electoral system and social cleavages.” Explain. (2021, 20 Marks)

Party systems are usually explained either institutionally, as with Maurice Duverger (Political Parties, 1951) on electoral rules, or sociologically, as with Seymour Martin Lipset and Stein Rokkan on “frozen” cleavages. India has one of the most fragmented party systems under first-past-the-post, and neither approach explains it alone. The outcome depends on how the electoral system, federalism and cleavages act on one another.

1. The electoral system: Duverger at the constituency level

  • Duverger’s law holds that plurality rule produces two-party competition, through a mechanical effect (a thin vote is under-rewarded) and a psychological one (voters desert hopeless parties). William Riker treated India as the standing exception.
  • Pradeep Chhibber and Ken Kollman (1998) resolved the anomaly. The law works within constituencies, where competition tends towards two serious contenders, but different pairs compete in different states. National multipartism is therefore a failure of aggregation. Rekha Diwakar (2007) qualifies this, since many constituencies are not bipolar.
  • First-past-the-post rewards concentration. In 2014 the BSP won 4.2% of the national vote and no seats, while the AIADMK won 37 seats on 3.3%.
  • Reserved seats with joint electorates force Scheduled Caste candidates to seek cross-caste votes. In 2024 the BSP failed to win even one of Uttar Pradesh’s 17 reserved seats.

2. Federal structure: the prize and the arena

  • A prize worth winning: police, land and schooling are state subjects, so regional parties can aim to govern.
  • Linguistic reorganisation (1956) made the boundaries of states coincide with those of cultural communities.
  • Centralisation drives aggregation. In The Formation of National Party Systems (2004), Chhibber and Kollman show that voters and elites back national parties when power sits at the Centre. The planned economy of the Jawaharlal Nehru years sustained the Congress; the loosening of central control after 1991 rewarded state parties; centrally branded welfare after 2014 helped renationalise the vote.
  • Separate arenas. The delinking of Lok Sabha and assembly elections after 1971 created state party systems with their own logic: bipolar Kerala, multipolar Uttar Pradesh, and Tamil Nadu’s Dravidian duopoly from 1967 to 2026.

3. Social cleavages: many and cross-cutting

  • Caste, language, religion, region and class cut across one another, which produces fragmentation rather than polarisation. Post-poll surveys found no sharp class cleavage in 2024.
  • Kanchan Chandra (Why Ethnic Parties Succeed, 2004) explains why caste becomes the currency of mobilisation. In a patronage democracy, voters use ethnic markers to judge who will deliver. This produced the BSP (Dalit), the SP and the RJD (OBC–Muslim) and the Akali Dal (Sikh).

The same cleavage has different effects under different institutions. Caste fragments Uttar Pradesh’s party system but consolidates Tamil Nadu’s, because the state arena and the electoral rule filter it differently.

Limits of the structural view

  • Agency matters: leadership, organisation and money are not structural outcomes.
  • Causation runs both ways: Paul Brass shows elites constructing the cleavages they mobilise, and parties reshape institutions, as the defeat of the 131st Amendment Bill in April 2026 showed.

Conclusion

No single variable explains India’s party system. Cleavages supply the potential parties, federalism supplies the arenas and the prizes, and first-past-the-post decides which cleavages win seats. The degree of centralisation then decides whether local systems add up to a national one, and that is why the system has swung between fragmentation and renationalisation without settling in either.
