Introduction: From One-Party Dominance to a Multiparty Polity
The evolution of India’s party system mirrors the transformation of Indian democracy itself.
From a one-party dominant structure under the Indian National Congress in the early
decades of Independence to the complex multiparty and coalition-led polity of the present,
Indian political dynamics have seen profound institutional and ideological shifts. The system
has transitioned from a centrist consensus underpinned by the Congress party to
increasingly fragmented and polarized politics, with the rise of regional parties, caste-based
mobilization, and a powerful Hindu nationalist right represented by the Bharatiya Janata
Party (BJP).
The Congress System: Rajni Kothari’s Framework and Nehruvian Foundations
The term “Congress System,” coined by political scientist Rajni Kothari, described a uniquely
Indian political structure in which the Indian National Congress was not merely a ruling party
but a broad-based umbrella institution that incorporated all shades of political opinion, ethnic
groups, castes, and classes. Unlike a standard two-party or multiparty competition model,
the Congress System functioned as a party of consensus and mediation, making electoral
politics a contest not between parties but within factions of the same party. This gave the
Congress immense staying power in the first two decades of independence.
The Congress’s dominance was not accidental—it emerged from its central role in the
nationalist struggle and its capacity to knit together diverse social and political
constituencies. During the Nehruvian period (1947–1964), the party operated on the basis of
a centrist ideology that balanced democratic socialism with moderate secular nationalism.
Nehru's personal authority, moral stature, and intellectual vision were key to maintaining
ideological unity within the Congress, even as it accommodated powerful regional leaders
and ideological factions. As Kothari pointed out, the Congress succeeded because it was
able to represent a diversity of interests through internal negotiation rather than
confrontation.
Despite this, the Congress was not without structural limitations. It lacked strong institutional
mechanisms for leadership transition and internal reform. The party's strength depended
heavily on Nehru’s stature, and with his death in 1964, cracks began to emerge. Internal
factionalism intensified, and although Lal Bahadur Shastri and later Indira Gandhi managed
to hold the party together, the balance of power gradually shifted from collective leadership
to a more centralized and personalized authority. This slow erosion of institutional norms
within the Congress laid the groundwork for its eventual decline.
Kothari's formulation also highlighted the system’s dependence on electoral dominance at
both national and state levels, as well as its ability to incorporate opposition through
co-optation rather than exclusion. However, this very dominance led to complacency,
resistance to organizational renewal, and a disconnect from grassroots concerns. By the late
1960s, as regional identities, caste-based mobilization, and economic discontent became
more pronounced, the Congress system began to unravel. The elections of 1967 exposed
this vulnerability, as Congress lost its monopoly in several states and opposition parties
began to assert themselves more forcefully.
Thus, while the Congress System was a product of both historical necessity and strategic
accommodation, its decline was rooted in its inability to reform itself institutionally and adapt
to a rapidly evolving political landscape. The end of the Congress System did not merely
