Two Indias

The 2024 Lok Sabha election produced a striking map. The BJP swept most of the Hindi belt, Uttar Pradesh, Bihar, Rajasthan, Madhya Pradesh, and Chhattisgarh, while the south went overwhelmingly to opposition parties. Tamil Nadu gave not one seat to the BJP. Kerala gave none. Telangana gave one. Karnataka gave the BJP only 17 of 28 seats, down from 25 in 2019.

This is not a new pattern. Tamil Nadu has not returned a Congress or BJP state government since 1967. Kerala has alternated between the Left and the Congress-led UDF for decades. The Dravidian parties, the TRS/BRS, and the Telugu Desam Party have built their identities partly in opposition to what they see as north Indian cultural and political dominance.

But the divide has sharpened in the past decade. Three policy decisions have made it existential for southern politicians: GST, delimitation, and the three-language policy. Each one intersects with the others, and together they constitute what southern leaders call a structural unfairness in how India is governed.

The fiscal argument

Southern states are net contributors to the central tax pool. Tamil Nadu, Karnataka, Kerala, Andhra Pradesh, and Telangana generate a disproportionate share of India's GST revenue, corporate tax, and income tax. Under the Finance Commission's horizontal devolution formula, they receive back less than they put in, a transfer to poorer, more populous northern states that is by design, not accident.

This would be unremarkable in any federal system; Germany's Finanzausgleich transfers money from Bavaria and Baden-Württemberg to Thuringia and Saxony. What makes it contentious in India is GST. Before 2017, states had their own indirect tax powers; they could set VAT rates, impose octroi, and adjust levies to attract investment. GST pooled those powers into a joint GST Council where the centre has decisive weight. Southern states gave up fiscal autonomy in exchange for a national market and a guaranteed revenue floor that ended in 2022.

The result: southern states run better schools, better hospitals, and lower fertility rates than most northern states, and are taxed on their success. Tamil Nadu's per-capita GST contribution is roughly three times Bihar's.

The delimitation threat

The seat-freeze expires after 2026. When the next Delimitation Commission constitutes, based on a census that has not yet been conducted, it will almost certainly result in more Lok Sabha seats for UP and Bihar, and proportionally fewer for Tamil Nadu, Kerala, and Andhra Pradesh.

The math is stark. Tamil Nadu's total fertility rate is around 1.7, below replacement. Bihar's is around 3.0. Over fifty years, that gap compounds. Tamil Nadu did what demographers asked: it educated women, expanded family planning, and brought fertility down. The reward, under population-based delimitation, is less political power.

Southern Chief Ministers have proposed alternatives: freeze the seat count further, expand the total number of seats significantly, or use a formula that weights development indicators alongside population. None of these has been adopted. The BJP, whose political strength is concentrated in the north, has not committed to a solution that would protect southern representation.

Language and culture

The three-language formula, Hindi, English, and a regional language, has been resisted in Tamil Nadu since 1937. The anti-Hindi agitation of 1965, which killed the plan to make Hindi the sole official language, remains the defining moment of Tamil political identity. The National Education Policy 2020 was read by Tamil politicians as a backdoor reimposition of the three-language formula, despite central government assurances.

The cultural dimension goes deeper than language policy. Dravidian politics rests on a theory of Dravidian civilisation as distinct from, and not subordinate to, north Indian Sanskrit culture. When a Prime Minister leads the consecration of a Ram temple, or when the Union Budget features imagery from north Indian religious tradition, southern politicians read it as cultural majoritarianism, an assertion that India's national culture is defined by a north Indian Hindu frame.

Is this a crisis?

India's federal system has absorbed north-south tension before. The linguistic reorganisation of states in 1956 was precisely a recognition that linguistic identity required a federal accommodation. The Sarkaria and Punchhi Commissions both documented centre-state friction without producing rupture.

What makes the current moment different is that multiple grievances have converged simultaneously, fiscal, demographic, and cultural, and the political counterpart of those grievances (opposition dominance in the south, BJP dominance in the north) has made compromise harder rather than easier. A BJP that does not need southern seats to form a government has limited electoral incentive to address southern concerns. A southern opposition that runs on anti-centre grievance has limited incentive to negotiate.

The compass places this entire set of questions on the Nation axis. The north-south divide is, at its root, a debate about what kind of federation India should be, a strong centre with regions, or a union of linguistically and culturally distinct nations that have pooled sovereignty for limited purposes.
