The Emergence and Impact of Coalition Politics in India

For the first four decades after Independence, one party governed at the Centre with little serious challenge. Then came 1989, and the rules of the game changed. No single party has been able to win a clear majority of Lok Sabha seats in most elections held between 1989 and 2014, which pushed parties into bargaining, negotiating, and stitching together alliances to govern. This shift from one-party rule to coalition government is one of the most important transformations in the country’s political history, and it tells us a great deal about how a deeply diverse society organises power.

From single-party dominance to a multi-party reality 🔗

In the decades after 1952, the Indian National Congress functioned as what political scientist Rajni Kothari called the “Congress System”: a dominant party that absorbed diverse social groups and ideologies within itself, winning sweeping majorities such as 364 of 489 seats in the first general election. Coalition politics was simply unnecessary when one party could accommodate almost everyone.

That arrangement began to crack. The first non-Congress government at the Centre arrived in 1977, when the Janata Party brought together several opposition groups to defeat Congress after the Emergency. It collapsed within two years due to internal contradictions, and Congress returned in 1980. But the underlying fragmentation never went away. The real turning point came with the 1989 general election, when Congress lost its historical majority and government began rotating among Congress-led, BJP-led, and third-party coalitions.

Why did coalitions become necessary? 🔗

Several forces converged to produce the coalition era. The most direct cause was the decline of the Congress. As the party lost its grip, the vacuum was filled by a crowded field of competitors rather than a single replacement.

Equally important was the rise of regional parties. Through the 1980s, outfits such as the Telugu Desam Party, DMK, AIADMK, Asom Gana Parishad, Samajwadi Party, and Bahujan Samaj Party grew into serious electoral forces. The Mandal Commission moment of 1990, when reservations for Other Backward Classes were implemented under V. P. Singh, deepened the political mobilisation of caste groups and gave regional and caste-based parties an even firmer base, as the political scientist Eswaran Sridharan has discussed in his analysis of India’s coalition politics.

These regional players gained enough seats that no national party could ignore them. With the vote base fragmented across linguistic, regional, and caste lines, forming a government required parties to combine their numbers. Coalition politics, in other words, was not an accident but the natural electoral expression of a society with 28 states, more than twenty official languages, and countless communities.

How coalitions are built 🔗

Coalitions in India come together in two broad ways, and the distinction matters for how stable they turn out to be.

Pre-poll and post-poll alliances 🔗

Pre-poll alliances are formed before voting, when parties agree to contest together, share seats, and present a common face to voters. The National Democratic Alliance under Atal Bihari Vajpayee is the classic example. Post-poll alliances are assembled after results are declared, when parties that fought separately negotiate to reach a majority. These tend to be more fragile because partners may have campaigned against one another and have fewer shared commitments.

The Common Minimum Programme 🔗

To hold ideologically varied partners together, Indian coalitions developed a distinctive instrument: the Common Minimum Programme (CMP). This is a negotiated document setting out the shared policy agenda that all partners agree to pursue, even where they disagree on much else. The CMP gained prominence precisely because coalition government became the norm in the 1990s, and it became a tool for managing disputes rather than letting them tear the government apart.

The three coalitions that defined the era 🔗

Three alliances illustrate the journey of coalition politics from instability towards durability.

The United Front (1996-1998) 🔗

After the 1996 election, a coalition of thirteen non-Congress, non-BJP parties formed the United Front, with TDP leader N. Chandrababu Naidu as its convener and Congress supporting it from outside. It was led first by H. D. Deve Gowda and then by I. K. Gujral. Its CMP emphasised secularism, economic reform, and social justice. The Front demonstrated that regional parties could collectively run the Centre, but it also exposed the weaknesses of post-poll arrangements. Dependent on outside Congress support, it proved short-lived and collapsed in 1998.

The National Democratic Alliance (NDA) 🔗

The BJP-led NDA, formed in 1998, became the success story of coalition politics. After a first government that lasted only thirteen days for want of numbers, Vajpayee returned and led a coalition that completed a full five-year term from 1999 to 2004. This was a landmark: it showed that a pre-poll coalition of many parties could deliver stable, durable governance rather than constant crisis. Its agenda prioritised national security, infrastructure, and economic growth.

The United Progressive Alliance (UPA) 🔗

In 2004, the Congress-led UPA came to power under Manmohan Singh, supported initially by the Left parties from outside on the basis of a CMP. The CMP and a coordination committee gave UPA-I a working framework for resolving differences among partners. Governing for a full decade until 2014, the UPA focused on social welfare schemes and inclusive growth, and its tenure stands as one of the longest-running coalition governments in the country’s history.

What coalitions changed about governance 🔗

Coalition politics reshaped how the country is governed, with both gains and costs.

Strengthening federalism and representation 🔗

The clearest benefit has been the empowerment of states and regions. When the national party depends on regional partners to survive, those partners gain real leverage over central policy, budgets, and development priorities. This decentralisation of power aligns with the constitutional vision of cooperative federalism and ensures that a wider range of social and regional interests find a voice at the Centre. Coalition governments, by their nature, are more inclusive and consensus-driven than single-party rule.

Instability and policy compromise 🔗

The costs are equally real. Governments became vulnerable to the withdrawal of support by partners, which toppled the administrations of V. P. Singh, I. K. Gujral, and Vajpayee’s first term. To keep allies happy, major reforms were sometimes diluted or delayed, a problem often described as policy paralysis. The authority of the Prime Minister could also weaken when survival depended on hard-bargaining partners, as the constraints faced during the United Front period showed. Critics argue that in this era, parties aligned and realigned based less on ideology and more on the arithmetic of power.

The 2014 break and the 2024 return 🔗

The coalition era paused in 2014, when the BJP won an outright majority on its own for the first time since 1984, repeating the feat in 2019. Although the NDA continued as an alliance, the BJP governed as the clearly dominant partner and was not bound by a CMP. Many wondered whether the coalition era had ended for good.

The 2024 general election answered that question. The BJP fell short of a majority on its own and had to rely on NDA partners, particularly Chandrababu Naidu’s TDP and Nitish Kumar’s JD(U), to retain power. Coalition bargaining returned, visible in special packages for Andhra Pradesh and Bihar and in negotiations over cabinet portfolios. This suggests that the single-party dominance of 2014 and 2019 may have been a cyclical phase rather than a permanent departure, and that in a society as diverse as this one, coalitions are likely to remain a recurring feature of national politics.

What do you think? Do coalition governments produce better representation by forcing diverse interests to negotiate, or do they trade away decisive governance for the sake of holding fragile alliances together? And as regional parties grow stronger, do you expect future coalitions to be built around shared ideology or simply around the arithmetic of winning power?
