Step 1: The Transition of the Indian Party System --- From One-Party Dominance to Multi-Party Coalitions:
The year 1989 represents a major turning point in the history of Indian democracy. The ninth general elections held in November 1989 brought an end to the “Congress System”---the era of single-party dominance that had characterized national politics since independence in 1947. Between 1989 and 2014, no single political party was able to secure an absolute majority on its own in the Lok Sabha. This necessitated the formation of multi-party coalition governments at the Centre, such as the National Front, the United Front, the National Democratic Alliance (NDA), and the United Progressive Alliance (UPA). This structural shift was driven by four key political and social factors.
Step 2: Factor 1 --- The Structural Decline of the Congress Hegemony:
• The Loss of the Catch-All Character: Under Jawaharlal Nehru and Indira Gandhi, the Congress party operated as a broad, catch-all social coalition that accommodated diverse class, caste, religious, and regional groups within its fold.
• Erosion of Public Trust: By the late 1980s, this multi-class consensus had significantly decayed. Issues like the Bofors scandal, administrative centralism, and the rise of regional grievances alienated major social groups (such as Muslims, Scheduled Castes, and middle peasant castes) from the party, leaving a political vacuum that could not be filled by any other single national party.
Step 3: Factor 2 --- The Rise of Regional Parties as National Power-Brokers:
• Assertiveness of States: Post-1989 saw a powerful growth of regional political parties representing distinct linguistic, cultural, and geographic aspirations (such as the DMK and AIADMK in Tamil Nadu, Telugu Desam Party in Andhra Pradesh, Samajwadi Party and Bahujan Samaj Party in Uttar Pradesh, and Rashtriya Janata Dal in Bihar).
• The Kingmaker Role: As the strength of national parties declined, these regional parties won a significant share of Lok Sabha seats. This made their support indispensable for any national coalition, transforming them from local actors into national power-brokers.
Step 4: Factor 3 --- Social Fracturing and Identity Politics (The Mandal and Dalit Waves):
• The Mandal Phenomenon: The implementation of the Mandal Commission recommendations in 1990 by the V.P. Singh government granted $27\%$ reservation to Other Backward Classes (OBCs) in federal government jobs. This triggered intense political mobilization among backward castes.
• Dalit Empowerment: Simultaneously, the mobilization of Scheduled Castes under the leadership of Kanshi Ram and the Bahujan Samaj Party (BSP) fractured the traditional, consolidated voting patterns of northern India. The electorate became highly fragmented along caste lines, leading to the growth of caste-specific regional parties and preventing any single party from winning a national majority.
Step 5: Factor 4 --- Post-Ideological Pragmatism and Alliance Engineering:
• Erosion of Ideological Rigidities: Before 1989, Indian political parties were divided by strong ideological boundaries (such as secularism, socialism, and nationalism). Post-1989, however, political survival and access to state power led to a era of pragmatism.
• Strategic Alliances: Parties became willing to set aside their core ideological differences to form pre-poll or post-poll alliances. For instance, in 1989, the National Front government under V.P. Singh was supported from the outside simultaneously by the right-wing BJP and the left-wing Communist parties. Later, the BJP successfully constructed the National Democratic Alliance (NDA) by allying with secular regional parties, showing that alliance engineering had replaced ideological purity.
