India’s Constitution set a 15-year deadline to make Hindi the sole official language. As that deadline arrived in 1965, Tamil Nadu erupted in protest, reshaping the state’s politics for decades.

Official language vs. national language: the Constitution names Hindi the Union’s official language for government business. It names no national language at all. This gap is the root of a lot of exam confusion.
Three-language formula: a later compromise encouraging schools to teach Hindi, English, and a regional language. It grew out of this agitation. Tamil Nadu has historically resisted the Hindi part.
1.What was the fifteen-year deadline?
The Constitution named Hindi in the Devanagari script as the Union’s official language. But it let English continue for official work too. That permission had a limit: just 15 years after 1950, that is, until 1965.
- Non-Hindi states, especially Tamil Nadu, feared losing out in jobs and exams once English ended.
- The rule sits in Article 343 of the Constitution.
- As 1965 drew near, that fear turned into organised protest.
2.What was the DMK’s “Day of Mourning”?
The DMK’s executive committee met on 8 January 1965 and made a decision. They declared 26 January, the date Hindi was due to become the sole official language, a “Day of Mourning.”
Party chief C.N. Annadurai asked volunteers to raise black flags across Tamil Nadu that day. He also called for burning Part XVII of the Constitution, the part holding the language rules.
The government moved first. Police detained Annadurai and many other DMK leaders the night before, under preventive custody.
True or false: Police detained C.N. Annadurai and many other DMK leaders the night before the planned 26 January protest.
3.How did a Madurai clash spread statewide?
On 25 January 1965, a clash between agitating students and Congress party workers broke out in Madurai. It spiralled out of control fast, and the rioting spread to other parts of Tamil Nadu within days.
- The protests turned large, and sometimes violent, under parties like the DMK.
- On that same day, 27-year-old Keelapaloor Chinnasamy set himself on fire at Tiruchi railway station, shouting pro-Tamil slogans. He became the agitation’s first martyr.
- His death triggered five more youth self-immolations in the days that followed, not fewer.
- Official figures put the death toll at around 70. Unofficial estimates claim higher numbers, though these aren’t independently confirmed.
True or false: Chinnasamy’s self-immolation calmed the situation and prevented further such deaths.
3.1Why did two Union Ministers resign?
Tamil Nadu’s Chief Minister M. Bhaktavatsalam had dismissed the agitation as mere “blasphemy.” That stance did not hold. On 11 February 1965, two Union Ministers from Madras resigned from Shastri’s cabinet.
C. Subramaniam and O.V. Alagesan quit together. They said they could not stay in a government fighting its own people. Their resignations showed the crisis had reached the top of the Union government.
4.How did Shastri’s assurance become law?
Prime Minister Lal Bahadur Shastri stepped in with a promise. He assured non-Hindi states that English would not be abruptly removed. That assurance calmed the immediate crisis, though distrust over language policy lingered for years.
The promise didn’t stay just a promise. The Official Languages Act, 1963, was formally amended in 1967 to let English continue indefinitely alongside Hindi.
The result became known as the “three-language formula,” encouraging Hindi, English, and a regional language in schools. Tamil Nadu has historically resisted the compulsory-Hindi part of it.
True or false: The 1967 amendment to the Official Languages Act let English continue indefinitely, rather than ending it.
5.How did Rajagopalachari reverse his own position?
C. Rajagopalachari, as Premier of Madras Presidency, made Hindi compulsory in schools back in 1938. That move sparked the very first anti-Hindi agitation, running 1937-40, led by Periyar E.V. Ramasamy.
By the 1960s, Rajagopalachari had reversed course completely. He now opposed Hindi imposition. He coined the slogan “English Ever, Hindi Never,” which became the 1965 agitation’s rallying cry.
6.How did this remake Tamil Nadu politics?
India has no constitutional “national language” at all, only an official language for Union government business. Article 343 and Article 351 cover the official language and the Union’s duty to spread Hindi, respectively. The agitation also fed broader south Indian worries about political and economic dominance by the Hindi belt.
The DMK rode this movement to power. In the 1967 election, the party ended twenty years of unbroken Congress rule in Madras State. Bhaktavatsalam, the sitting Chief Minister, lost his own Sriperumbudur seat to a DMK candidate.
The English-indefinitely compromise stayed a live policy question. It gets revisited whenever new education or language policies come up.
7.Exam Angle: the usual traps here
- Trap 1: India has no constitutional “national language,” only an official language for Union business. A question calling Hindi India’s “national language” is testing exactly this gap.
- Trap 2: Rajagopalachari’s own position flipped. He made Hindi compulsory in Madras in 1938, then became the anti-imposition movement’s biggest voice by the 1960s. Don’t assume one leader held one view across decades.
- Trap 3: the 1963 Official Languages Act and its 1967 amendment are often confused. The original Act set the framework. The amendment is what actually made English’s continuation indefinite, not automatic from 1963.
