From Political Margins to Power: How the BJP Scripted a Historic Victory in West Bengal After Decades of Struggle
For the first time in its political history, Bharatiya Janata Party has formed a government in West Bengal — a moment that marks not just an electoral victory, but a profound political shift in one of India’s most ideologically influential states.
For the BJP and the broader ideological family associated with it, this triumph carries immense symbolic importance.
Bengal has long been regarded as the intellectual and political home of Syama Prasad Mookerjee, one of the founding figures of the Bharatiya Jana Sangh (BJS), the political predecessor of today’s BJP.
Yet, despite that historical connection, the BJP remained politically insignificant in Bengal for decades.
Its rise from the fringes of state politics to forming the government in 2026 is a story shaped by ideological persistence, shifting social coalitions, a political vacuum, strategic reinvention, and years of intense ground-level battles.
The roots of political Hindutva in Bengal go back to the pre-independence era. Syama Prasad Mookerjee, who began his political journey in the Congress before joining the Hindu Mahasabha, eventually founded the Bharatiya Jana Sangh and became its first president.
After he died in 1953 while detained in Kashmir, the BJP never found another Bengali leader of comparable stature who could command mass support in the state.
For decades thereafter, Bengal politics remained dominated first by the Congress and then by the Left Front led by the Communist Party of India (Marxist).
When the BJP contested its first West Bengal assembly election in 1982, it barely registered its presence.
For years, the party remained electorally marginal, unable to penetrate Bengal’s deeply entrenched political culture shaped by Left ideology, trade union politics and regional identity.
The BJP’s organisational network was weak, its vote share negligible, and its appeal largely confined to isolated pockets.
The political landscape, however, began to change gradually in the late 2000s. Ironically, the BJP’s eventual rise was aided by the collapse of the Left Front and the contradictions within Bengal’s anti-Left politics itself.
The emergence of the All India Trinamool Congress under Mamata Banerjee initially pushed the BJP further into the margins.
The TMC’s resurgence was driven by widespread anger against the Left Front over controversial land acquisition attempts in Singur and Nandigram, where peasants fiercely resisted industrial projects.
The Left, which once built its politics around peasant mobilisation, suddenly found itself accused of suppressing the very rural classes it had once empowered.
At the same time, growing Muslim dissatisfaction with the Left Front — fuelled by findings in the Sachar Committee report highlighting the socio-economic backwardness of Muslims in West Bengal, along with controversies such as the Rizwanur Rahman case — eroded the Communist base further.
The TMC successfully consolidated anti-Left votes, especially among Muslims, making it politically difficult for the party to maintain any visible relationship with the BJP.
As the TMC and the Left fought for dominance, the BJP watched from the sidelines. In the 2009 Lok Sabha elections and the 2011 assembly elections that ended 34 years of Communist rule, the BJP remained a peripheral player.
But beneath the surface, Bengal’s political structure was beginning to crack.
The first real breakthrough came in the 2014 Lok Sabha elections.
In a fiercely contested four-cornered battle involving the TMC, Left, Congress and BJP, the BJP won two parliamentary seats in Bengal for the first time on its own and matched the CPI(M) in seat tally.
Though still far from power, the party had announced its arrival as a serious contender.
The 2016 assembly elections did not immediately translate into further success for the BJP, but they deepened the crisis within the Left ecosystem.
The CPI(M)’s controversial alliance with the Congress confused its traditional support base and weakened its ideological credibility.
The Left not only lost badly but also surrendered its position as the principal opposition to the Congress — an unimaginable decline for a party that had ruled Bengal uninterrupted for over three decades.
The real turning point arrived during the violent and highly controversial 2018 panchayat elections. In large parts of rural Bengal, opposition candidates alleged intimidation and widespread obstruction.
Roughly one-third of seats reportedly went uncontested in favour of the ruling TMC. Yet, amid the turbulence, the BJP emerged as the second-largest political force in rural Bengal — a significant development in a state where control over the countryside often determines political power.
That momentum exploded dramatically in the 2019 Lok Sabha elections. The BJP stunned political observers by winning 18 out of Bengal’s 42 parliamentary seats and securing nearly 40 per cent vote share.
The result transformed the political narrative overnight. For the first time, the BJP looked capable of capturing power in Bengal.
However, the road ahead proved far more difficult than expected.
The 2021 assembly elections exposed the brutal realities of Bengal’s electoral arithmetic. Although the BJP retained much of its 2019 vote share, its seat tally collapsed because of the first-past-the-post electoral system.
The party secured strong vote percentages but failed to convert them into enough seats. The 2024 Lok Sabha election results reinforced that limitation, with the BJP unable to recreate its 2019 wave.
The decisive breakthrough finally came in 2026.
One of the BJP’s biggest strengths lies in its consolidation of support among Scheduled Castes and Scheduled Tribes.
Historically, the party had performed relatively better in SC and ST reserved constituencies compared to general seats, but after 2014, it significantly expanded that advantage.
These regions became the backbone of the BJP’s Bengal strategy.
In the 2021 elections, the BJP’s strike rate in unreserved constituencies was modest, but it performed strongly in SC and ST reserved seats. By 2026, those gains became overwhelming.
The BJP dramatically improved its performance not just in reserved constituencies but also in general seats, reflecting a wider consolidation of Hindu votes cutting across caste and regional divisions.
District-wise voting patterns suggest that the BJP benefited from two simultaneous shifts.
In Muslim-majority districts, sections of Muslim voters appear to have moved towards non-BJP parties, while Hindu voters consolidated heavily behind the BJP.
In most other districts, the BJP gained support at the expense of both the TMC and smaller opposition parties.
Perhaps the most symbolically important development was the BJP’s strong performance in Kolkata — Bengal’s cultural, intellectual and economic heart.
The city’s shift indicated that the BJP’s appeal was no longer limited to anger against the ruling establishment; it had also gained ideological traction in spaces once considered resistant to Hindutva politics.
Now, with Suvendu Adhikari preparing to take oath as West Bengal’s first BJP chief minister at the historic Brigade Parade Ground, Bengal enters a completely new political era.
Yet, the BJP’s victory also raises difficult questions. Can the party sustain its support in a politically volatile state like Bengal?
Will the TMC recover once it is no longer the entrenched ruling force? Can the Left and Congress rebuild themselves?
And perhaps most importantly, can the BJP govern Bengal without reproducing the same aggressive party-controlled political culture that critics say has dominated the state for decades under successive regimes?
History in Bengal has rarely stood still for long. Political tides have repeatedly overturned certainties once considered permanent.
The BJP’s rise to power is undoubtedly historic, but whether this marks the beginning of long-term dominance or merely another dramatic chapter in Bengal’s ever-changing political story will only become clear with time.
