Cultural confluence programmes such as Kashi Tamil Sangamam are tools of soft national integration. Critically examine in the context of India's linguistic federalism.

In a federation built on language-based states, national unity has to come from persuasion, not imposition. The Ministry of Education runs Kashi Tamil Sangamam (KTS) under Ek Bharat Shreshtha Bharat to connect Tamil Nadu and Kashi. Its fifth edition (2026) is centred on the Thirukkural [1].

KTS as a tool of soft integration

• Language learning in reverse: under KTS 4.0's 'Tamil Karkalam', Tamil was taught in 50 Varanasi schools [2]. Children in the Hindi belt learning Tamil runs against the fear of "Hindi imposition".
• Fits NEP 2020: the policy says no language will be imposed on any State and that two of the three languages a child learns should be native to India [4].
• Constitutional backing: it puts Article 51A(f) (duty to preserve our composite culture) into practice.
• Ethics over monuments: the 5.0 theme moves from sacred sites to a widely shared text on conduct [1].
• Broad participation: about 1,400 delegates in seven categories (students, artisans, farmers, women and others), plus outreach in 1,000 higher-education institutions [1].

Limits seen through linguistic federalism

• Home state left out: the partner list includes the UP Government and many Union ministries, but not Tamil Nadu's government [1]. A Rajya Sabha question (2023) asked why the Tamil Nadu government and Tamil scholars were not consulted, and what the event cost [5].
• Mostly one-way: about 1,400 Tamils travel north, but only 300 Kashi students went south [3]. That is weak for a "sangamam" (a meeting of two streams).
• Religious framing: every stop, Varanasi, Prayagraj and Ayodhya, is a Hindu pilgrimage centre in one state [1]. This risks tying Tamil identity to a single religious map.
• Counts inputs, not results: releases report headcounts, not outcomes. Even the parent EBSB campaign is assessed mainly on participation and footfall [6].
• A better model exists: Saurashtra Tamil Sangamam was launched in Chennai. It reconnected a living community with its Gujarati roots [7].

KTS shows that culture can build unity, but in a linguistic federation this works only if both sides own it. The way forward:

• make Tamil Nadu a co-host;
• expand the reverse exchange;
• add places of learning to the itinerary;
• publish cost and outcome data.

This would turn KTS into real cooperative cultural federalism and fulfil Article 51A(f) and the idea of Ek Bharat Shreshtha Bharat.
