Overview

India's political landscape underwent a fundamental transformation from the late 1980s onwards. The era of Congress dominance — often called the "Congress System" by political scientist Rajni Kothari — gave way to an era of multi-party competition and coalition politics. The 1989 general election marked the definitive end of single-party majority at the centre (with a brief exception in 1984), ushering in a period of hung parliaments, coalition governments, and the dramatic rise of regional parties. The implementation of the Mandal Commission recommendations, the Babri Masjid demolition, economic liberalisation, and the emergence of the BJP as a national alternative fundamentally reshaped Indian democracy. This era also saw critical institutional reforms through the anti-defection law and Election Commission interventions.


The Congress System and Its Decline

The Congress Dominance Phase (1947–1989)

Period Feature
1947–1967 Near-total Congress dominance at the Centre and in most states; Nehru's personal stature and the legacy of the freedom struggle sustained Congress hegemony
1967 — First crack Congress lost power in several states (Kerala, Tamil Nadu, West Bengal, Orissa, Punjab, Bihar); formation of non-Congress governments using coalition strategies — the Samyukta Vidhayak Dal (United Legislative Front) experiments
1969 Congress split into Congress (R) under Indira Gandhi and Congress (O) under the Syndicate (Morarji Desai, Kamaraj, etc.)
1971 Indira Gandhi's sweeping victory on the "Garibi Hatao" platform; re-established Congress dominance
1975–77 Emergency (1975–77); Congress defeated in 1977 by the Janata Party — India's first non-Congress government at the Centre under Morarji Desai
1980 Congress returns under Indira Gandhi
1984 Rajiv Gandhi wins the largest majority in Indian electoral history (414/533 seats) after Indira Gandhi's assassination
1989 End of Congress dominance — Congress reduced to 197 seats; hung parliament; dawn of coalition era

Factors Behind Congress Decline

Factor Detail
Anti-incumbency Cumulative resentment against Congress governance — corruption, dynastic politics, authoritarian tendencies (Emergency)
Rise of identity politics Mandal Commission (OBC mobilisation), Hindutva politics (BJP), and regional/ethnic identities created competing political constituencies
Regional aspirations Linguistic, ethnic, and sub-national identities found political expression through regional parties
Economic dissatisfaction Uneven development and rural distress led voters to seek alternatives
Weakening of Congress organisation Centralisation under the Nehru-Gandhi family; decline of grassroots organisation; inability to accommodate diverse social groups

The Rise of Regional Parties

Major Regional Parties and Their Impact

Party State/Region Key Leaders Significance
DMK / AIADMK Tamil Nadu Karunanidhi / M.G. Ramachandran, Jayalalithaa Dravidian parties dominated Tamil politics since 1967; Congress has not won TN on its own since 1962
TMC (Trinamool Congress) West Bengal Mamata Banerjee Ended 34 years of Left Front rule in West Bengal (2011)
SP (Samajwadi Party) Uttar Pradesh Mulayam Singh Yadav, Akhilesh Yadav OBC-Muslim politics in India's largest state
BSP (Bahujan Samaj Party) Uttar Pradesh Kanshi Ram, Mayawati Dalit political assertion; Mayawati was India's first Dalit CM of a major state (UP, 1995)
TDP (Telugu Desam Party) Andhra Pradesh/Telangana N.T. Rama Rao, Chandrababu Naidu Founded 1982; challenged Congress dominance in AP; key NDA ally
JD(U) (Janata Dal United) Bihar Nitish Kumar Key coalition partner at Centre; Bihar politics
Shiv Sena Maharashtra Bal Thackeray, Uddhav Thackeray (split 2022) Regional identity politics; Marathi manoos; split into two factions
AGP / BPF Assam Prafulla Kumar Mahanta Assamese identity and anti-foreigner movements
SAD (Shiromani Akali Dal) Punjab Parkash Singh Badal Sikh political representation; long-time BJP ally
NCP / SCP Maharashtra Sharad Pawar (split 2023) Maharashtra politics; coalition player at Centre
JMM (Jharkhand Mukti Morcha) Jharkhand Shibu Soren, Hemant Soren Tribal politics; statehood movement

Why Regional Parties Rose

Factor Explanation
Federal structure India's federal system provides space for state-level parties to govern and leverage power at the Centre
Social diversity Caste, language, ethnicity, and religion create constituencies that national parties cannot fully represent
State-level issues Irrigation, land reform, local development, and regional identity create demand for local representation
Coalition leverage In hung parliaments, regional parties become kingmakers — able to extract policy concessions and ministerial positions
Charismatic leaders Many regional parties built around strong personalities (NTR, MGR, Jayalalithaa, Mamata Banerjee, Naveen Patnaik)

Anti-Defection Law — The Tenth Schedule

Background

Feature Detail
Problem After the 1967 elections, rampant party-hopping by legislators destabilised state governments; by one estimate, almost 50% of the 4,000 legislators elected in 1967 and 1971 subsequently defected; the phenomenon was called "Aaya Ram, Gaya Ram" (after a Haryana MLA who switched parties multiple times in a single day in 1967)
Solution 52nd Constitutional Amendment Act, 1985 — introduced the Tenth Schedule to the Constitution
Passed Lok Sabha: 30 January 1985; Rajya Sabha: 31 January 1985; Presidential assent: 15 February 1985; effective: 18 March 1985
Government Rajiv Gandhi government — enacted immediately after securing a massive majority in the 1984 elections

Key Provisions of the Tenth Schedule

Provision Detail
Grounds for disqualification A member is disqualified if they (a) voluntarily give up membership of their political party, or (b) vote or abstain contrary to the party whip without prior permission
Independent members If an independently elected member joins a political party after election, they are disqualified
Nominated members Nominated members have 6 months from taking their seat to join a political party; joining a party after that period leads to disqualification
Decision-making authority The Speaker (Lok Sabha / State Assembly) or Chairman (Rajya Sabha / State Legislative Council) decides disqualification petitions
Exception — merger Originally, a "split" (1/3rd of members) was permitted. The 91st Constitutional Amendment (2003) removed the split provision; now only a merger (2/3rds of members of a legislative party merging with another party) is exempt from disqualification

Criticisms and Debates

Criticism Explanation
Speaker's bias The Speaker (who often belongs to the ruling party) decides defection cases — no fixed time limit for decisions; partisan delays are common
Stifles dissent MPs/MLAs cannot vote according to conscience — forced to follow the party whip on all matters, reducing the role of individual legislators
Wholesale defection The law prevents individual defection but allows wholesale party mergers (2/3rds) — the "bulk defection" loophole
Supreme Court intervention In Kihoto Hollohan vs. Zachillhu (1992), the Supreme Court upheld the law's validity but ruled that the Speaker's decisions are subject to judicial review

Election Commission — Institutional Reforms

Key Reforms

Reform Year Details
Multi-member Election Commission 1993 EC expanded from single CEC to three members (CEC + 2 ECs); the Chief Election Commissioner can only be removed by impeachment (like a Supreme Court judge)
Model Code of Conduct Evolved over time Enforced strictly from the announcement of elections; restricts government from making populist announcements
EVM introduction 2000s Electronic Voting Machines replaced paper ballots; VVPAT (Voter Verifiable Paper Audit Trail) introduced for transparency
NOTA 2013 "None of the Above" option on ballot — following Supreme Court direction in PUCL vs. Union of India
Voter ID 1993 onwards Photo ID cards (EPIC) to prevent bogus voting
Expenditure limits Ongoing Candidates' spending capped; EC monitors campaign expenditure

T.N. Seshan's Legacy

Feature Detail
Who T.N. Seshan — Chief Election Commissioner (1990–1996)
Impact Transformed the Election Commission from a largely passive body into a powerful, assertive institution; strictly enforced the Model Code of Conduct; cracked down on booth-capturing, money power, and misuse of government machinery; his tenure is credited with making Indian elections significantly freer and fairer

Coalition Dynamics — Advantages and Challenges

Aspect Advantages Challenges
Representation Broader representation of India's diversity — regional, linguistic, and social interests get a voice at the Centre Instability — governments vulnerable to withdrawal of support by allies; frequent crises
Federal balance Regional parties ensure that state interests are represented in national policy-making Policy paralysis — need for consensus among coalition partners slows decision-making
Power-sharing Prevents concentration of power in a single party; checks authoritarianism Blackmail politics — small parties can hold the government hostage for disproportionate concessions
Consensus Encourages negotiation and accommodation among diverse groups Lack of accountability — no single party takes full responsibility for governance
Democratic depth Brings marginalised communities (Dalits, OBCs, tribals) into mainstream politics Ideological incoherence — coalitions may include parties with contradictory ideologies

Key Constitutional and Political Developments

Development Year Significance
Mandal Commission implementation 1990 27% OBC reservation in central government jobs; transformed India's social politics permanently
Babri Masjid demolition 1992 Communal polarisation; rise of BJP; challenged the secular framework
52nd Amendment (Anti-Defection Law) 1985 Curbed party-hopping; stabilised legislatures but limited legislative dissent
73rd and 74th Amendments 1992 Constitutional status to Panchayati Raj and Municipalities; deepened grassroots democracy
91st Amendment 2003 Removed the "split" exception from anti-defection law; capped Council of Ministers at 15% of Lok Sabha/Assembly strength
RTI Act 2005 Transparency and accountability in governance
Representation of People Act amendments Various Regulated electoral process, disclosure of criminal records, expenditure limits

Exam Strategy

Prelims: Focus on the anti-defection law — 52nd Amendment (1985), Tenth Schedule, 91st Amendment (2003, removed split provision). Know the coalition governments and their PMs: V.P. Singh (1989), Deve Gowda and Gujral (1996-98), Vajpayee (1999-2004), Manmohan Singh (2004-14). Remember the Mandal Commission (B.P. Mandal, 27% OBC reservation, V.P. Singh implemented 1990). The "Aaya Ram Gaya Ram" phrase (1967, Haryana) is a classic one-liner. Know T.N. Seshan's role in EC reforms.

Mains: Be prepared to discuss the impact of coalition politics on governance, federalism, and policy-making in India. Common questions include: Has the coalition era strengthened or weakened Indian democracy? What is the role of regional parties in national politics? Analyse the anti-defection law — has it served its purpose? Discuss the impact of the Mandal Commission on Indian society and politics. The relationship between identity politics (caste, religion, region) and electoral democracy is a high-value Mains theme.
