Coalition politics, regionalisation & the contemporary era
The rise of coalition governments, the regionalisation of Indian politics after 1989, Mandal-Mandir realignments, and the federal turn of the contemporary era.
The end of one-party dominance
The Congress 'system' described by Rajni Kothari—a dominant party absorbing dissent through internal factions—governed India's first three decades. Its terminal decline is dated to two ruptures. The first was the Congress split of 1969, when Indira Gandhi's faction (Congress (R)) broke from the Syndicate's Congress (O), personalising power around the leader. The second was the post-Emergency election of March 1977, when the Janata Party coalition under Morarji Desai delivered the first non-Congress government at the Centre, ending Congress's monopoly after thirty years.
The decisive structural shift, however, came in 1989. V.P. Singh's National Front, supported from outside by both the BJP and the Left, formed a minority government—inaugurating the era of multi-party coalitions and 'outside support' that defined the next quarter-century. Between 1989 and 2014 no single party won a Lok Sabha majority. India was governed by the National Front (1989–90), the Chandra Shekhar interregnum, the Narasimha Rao minority government (1991–96, which famously survived the 1993 confidence vote), the United Front (1996–98) under Deve Gowda and I.K. Gujral, the BJP-led National Democratic Alliance (NDA, 1998–2004) under Atal Bihari Vajpayee, and the Congress-led United Progressive Alliance (UPA, 2004–14) under Manmohan Singh.
Mandal, Mandir and Market
Three forces—captured in the shorthand 'Mandal, Mandir, Market'—remade the party system around 1990. Mandal: V.P. Singh's August 1990 decision to implement the Mandal Commission report (27% OBC reservation in central services), upheld with modifications in Indra Sawhney v. Union of India (1992), mobilised intermediate and backward castes and powered parties such as the Samajwadi Party, RJD and the expanded BSP. Mandir: the Ram Janmabhoomi movement, L.K. Advani's 1990 rath yatra, and the demolition of the Babri Masjid on 6 December 1992 consolidated a Hindutva vote that lifted the BJP from 2 seats (1984) to 161 (1996). Market: the balance-of-payments crisis of 1991 forced the liberalisation begun by Rao and Manmohan Singh, decoupling economic policy from electoral cycles and creating a broad pro-reform consensus across coalitions.
The result was the regionalisation of representation. Parties rooted in single states—DMK and AIADMK in Tamil Nadu, TDP in Andhra, Akali Dal in Punjab, Trinamool in West Bengal, BJD in Odisha, JD(U) and RJD in Bihar—became indispensable coalition partners, extracting policy concessions and central transfers. The 52nd Amendment (1985) anti-defection law, codified in the Tenth Schedule, attempted to discipline this fragmentation by penalising floor-crossing, though the 'split' loophole survived until the 91st Amendment (2003) tightened it.
This era also embedded cooperative-federal institutions: the Inter-State Council (Article 263, activated 1990 on the Sarkaria Commission's advice) and, later, the GST Council (Article 279A, 2016) and NITI Aayog (2015), which replaced the Planning Commission.
