Sukhdev Thapar birth anniversary observed on 15 May 2026 — HSRA strategist hanged with Bhagat Singh and Rajguru in 1931.
Why in News
India observed the birth anniversary of Shaheed Sukhdev Thapar on 15 May 2026, marking 119 years since the birth of one of the principal strategists of the Hindustan Socialist Republican Association (HSRA). Born on 15 May 1907 in Ludhiana, Punjab, Sukhdev played a central role in planning the assassination of British police officer J.P. Saunders in December 1928 — an act of retaliation for the lathi charge that led to the death of Lala Lajpat Rai. He was tried in the Lahore Conspiracy Case alongside Bhagat Singh and Shivaram Rajguru, and the three were hanged in Lahore Jail on 23 March 1931, a date India today commemorates as Shaheed Diwas (Martyrs' Day). The anniversary has prompted renewed focus on the HSRA's revolutionary tradition, its evolution from the Hindustan Republican Association (1924), and the values of sacrifice, patriotism and valour that the trio came to embody.

Early life and education
Sukhdev Thapar was born on 15 May 1907 in Ludhiana, Punjab, to Ramlal Thapar and Ralli Devi. He was raised partly by his uncle Lala Achint Ram, a prominent freedom fighter in Lahore, in an atmosphere already steeped in nationalist politics. He studied at National College, Lahore, founded by Lala Lajpat Rai as a 'national' alternative to Government colleges — the same institution that produced Bhagat Singh, Bhagwati Charan Vohra and several other future revolutionaries. National College became the crucible where Sukhdev imbibed both Indian nationalism and the socialist literature that would shape his politics. By his late teens he had given up the prospect of a settled professional career, choosing instead the path of revolutionary nationalism.
Naujawan Bharat Sabha and HSRA
In 1926, along with Bhagat Singh and others, Sukhdev co-founded the Naujawan Bharat Sabha in Lahore — a youth organisation that combined cultural nationalism with secular, socialist ideas and sought to mobilise students and workers against colonial rule. Sukhdev was its principal organiser in Punjab. The Sabha became one of the channels feeding revolutionaries into the older Hindustan Republican Association (HRA), founded in 1924 under leaders such as Sachindranath Sanyal and Ram Prasad Bismil. After a famous meeting at Feroz Shah Kotla, Delhi in September 1928, the HRA was reconstituted as the Hindustan Socialist Republican Association (HSRA), explicitly committed to the goal of a socialist republic through armed revolution. Sukhdev became a key strategist of the HSRA's Punjab unit.
Saunders killing and Lahore Conspiracy Case
On 17 November 1928, Lala Lajpat Rai died of injuries from a lathi charge ordered against an anti-Simon Commission protest in Lahore. The HSRA decided to retaliate. On 17 December 1928, Bhagat Singh and Shivaram Rajguru shot dead John P. Saunders, an Assistant Superintendent of Police, outside the District Police Headquarters in Lahore — they had actually intended to kill James A. Scott, the officer who had ordered the lathi charge. Sukhdev Thapar was a central planner of the operation. Following the Central Assembly bomb-throwing (8 April 1929) by Bhagat Singh and Batukeshwar Dutt, a sweeping investigation drew Sukhdev in. He was charged in the Lahore Conspiracy Case, a special tribunal trial held under an ordinance with limited defence rights.
Martyrdom on 23 March 1931
On 7 October 1930, the special tribunal sentenced Bhagat Singh, Sukhdev Thapar and Shivaram Rajguru to death, while several other accused received life imprisonment. Despite nationwide appeals and a Round Table Conference unfolding in London, the British colonial authorities went ahead with executions, advancing them by a day. The three were hanged on the evening of 23 March 1931 in Lahore Central Jail, their bodies hurriedly cremated on the banks of the Sutlej near Hussainiwala to prevent public mourning. The trio's deaths set off massive protests across India, helped consolidate the 'revolutionary' strand of the freedom struggle, and made March 23 a permanent date of national remembrance — Shaheed Diwas (Martyrs' Day).
Legacy and values
Sukhdev Thapar is remembered today not merely as a martyr but as a strategic mind of the HSRA — the comrade who, alongside Bhagat Singh, helped translate revolutionary fervour into organised planning. His brief life reflects the values of sacrifice, patriotism, intellectual courage and valour. He is commemorated through the Hussainiwala National Martyrs' Memorial (Firozpur, Punjab), where the trio were cremated; through 15 May as his birth anniversary; and through 23 March as Shaheed Diwas. Several State and Central institutions — schools, blocks, public squares — bear his name. Government schemes and military training institutions invoke the HSRA legacy as a model of selfless service to the nation.

- C.Shivaram Rajguru
- D.Chandrashekhar Azad
tap to reveal answer
Answer: A. Shaheed Sukhdev Thapar
Shaheed Sukhdev Thapar was born on 15 May 1907 in Ludhiana, Punjab. Bhagat Singh was born on 28 September 1907, Rajguru on 24 August 1908, and Chandrashekhar Azad on 23 July 1906 — none on 15 May.

- A.Feroz Shah Kotla, Delhi
- B.Lahore Central Jail, Punjab
- C.Allahabad, United Provinces
- D.Kanpur, United Provinces
tap to reveal answer
Answer: A. Feroz Shah Kotla, Delhi
The HSRA was formed by reorganising the Hindustan Republican Association at a meeting at Feroz Shah Kotla, Delhi in September 1928. The other places — Lahore, Allahabad and Kanpur — were important revolutionary centres but not the venue of its formation.
Q3. The 'Lahore Conspiracy Case' is best described as:
- A.The trial of Bhagat Singh, Sukhdev Thapar, Shivaram Rajguru and others for the 1928 Saunders assassination and related revolutionary activity
- B.The trial of the Kakori Train Robbery accused in Lucknow conducted under the Indian Penal Code with regular sessions-court procedure throughout
- C.A criminal case against participants of the 8 April 1929 Central Assembly bombing alone, without inclusion of any other revolutionary actions
- D.A 1921 trial against Lala Lajpat Rai for sedition under the Indian Penal Code by the British Government in colonial Punjab province
tap to reveal answer
Answer: A. The trial of Bhagat Singh, Sukhdev Thapar, Shivaram Rajguru and others for the 1928 Saunders assassination and related revolutionary activity
The Lahore Conspiracy Case was the special-tribunal trial of Bhagat Singh, Sukhdev, Rajguru and other revolutionaries primarily for the December 1928 Saunders killing and the HSRA's broader activity. The Kakori case (1925) and the Assembly bomb case are distinct. There was no 1921 trial of Lala Lajpat Rai of this form.
Q4. Consider the following pairs about Indian revolutionaries and their birth places:
1. Sukhdev Thapar — Ludhiana, Punjab
2. Bhagat Singh — Banga (Lyallpur district, undivided Punjab)
3. Shivaram Rajguru — Khed, Pune district, Maharashtra
4. Chandrashekhar Azad — Bhavra, Madhya Pradesh
Which of the above pairs is/are correctly matched?
- A.1, 2, 3 and 4
- B.1 and 2 only
- C.2 and 3 only
- D.1, 3 and 4 only
tap to reveal answer
Answer: A. 1, 2, 3 and 4
All four pairs are correct. Sukhdev — Ludhiana; Bhagat Singh — Banga in Lyallpur district (undivided Punjab, now Pakistan); Rajguru — Khed, Pune; Chandrashekhar Azad — Bhavra (then Alirajpur, now Madhya Pradesh). Hence all four pairs are correctly matched.
Q5. Consider the following statements:
1. Sukhdev co-founded the Naujawan Bharat Sabha in Lahore in 1926.
2. The HSRA evolved from the Hindustan Republican Association founded in 1924.
3. Sukhdev, Bhagat Singh and Rajguru were hanged in Delhi's Tihar Jail.
4. March 23 is observed as Shaheed Diwas in India.
Which of the above statements is/are correct?
- A.1, 2 and 4 only
- B.1, 2, 3 and 4
- C.1 and 3 only
- D.2 and 4 only
tap to reveal answer
Answer: A. 1, 2 and 4 only
Statements 1, 2 and 4 are correct — Naujawan Bharat Sabha (Lahore, 1926), HRA-to-HSRA evolution (1924 to 1928), and 23 March as Shaheed Diwas. Statement 3 is incorrect — the three were hanged in Lahore Central Jail, not Tihar.
Q6. Consider the following statements:
1. Saunders was killed in Lahore on 17 December 1928.
2. The HSRA's intended target was James A. Scott, who had ordered the lathi charge on Lala Lajpat Rai.
3. Sukhdev Thapar was one of the key planners of the operation.
4. The killing was committed by Bhagat Singh and Rajguru.
How many of the above statements are correct?
- A.All four
- B.Only three
- C.Only two
- D.Only one
tap to reveal answer
Answer: A. All four
All four statements are correct. Saunders was killed in Lahore on 17 December 1928, in a case of mistaken identity intended for James A. Scott, who had ordered the lathi charge that fatally injured Lala Lajpat Rai. Sukhdev planned the operation; Bhagat Singh and Rajguru executed it. Hence all four are correct.
Q7. Bhagat Singh, Sukhdev Thapar and Shivaram Rajguru were cremated on the banks of the Sutlej near which place?
- A.Hussainiwala, near Firozpur in Punjab
- B.Wagah, near Amritsar in Punjab
- C.Patiala, in eastern Punjab
- D.Kapurthala, in central Punjab
tap to reveal answer
Answer: A. Hussainiwala, near Firozpur in Punjab
The trio's bodies were hurriedly cremated by the British near Hussainiwala on the banks of the Sutlej, close to Firozpur in Punjab. The site is now the Hussainiwala National Martyrs' Memorial. Wagah, Patiala and Kapurthala are unrelated.
The revolutionary stream of the Indian freedom struggle, exemplified by the HRA and later the HSRA, is often presented as a parallel and supplementary track to the Indian National Congress's mass-mobilisation politics. Sukhdev Thapar — a young Ludhiana-born intellectual — was at the strategic centre of this stream during its most intense phase between 1926 and 1931. His martyrdom along with Bhagat Singh and Rajguru in 1931 hardened public sentiment against colonial rule and ensured that revolutionary nationalism remained a permanent strand in India's collective memory.
- Two streams of the freedom struggleThe HSRA's revolutionary politics complemented — rather than rivalled — the **Congress-led mass movements** (Non-Cooperation, Salvation, Civil Disobedience), exposing colonial repression and putting **mass civil-disobedience leaders in a stronger negotiating position**.
- Use of special tribunals and ordinancesThe **Lahore Conspiracy Case** highlighted how colonial governments used **ordinance-based special tribunals** to bypass due process — a cautionary parallel that remains relevant when modern democracies debate **anti-terror and special-court procedures**.
- Symbol of selfless serviceSukhdev, Bhagat Singh and Rajguru have become **transcendent symbols of selfless service** — invoked across the political spectrum, in school curricula, public art and military commemorations. Their values are core to **civic education** in India.
- Avoiding hagiography, recovering complexityHistoriography must move beyond hagiography to engage with the HSRA's **secular socialist ideology**, its critique of communalism, and its **internal debates on violence** — to fully honour Sukhdev's intellectual contribution, not just his martyrdom.
- Living memoryMemorials like **Hussainiwala**, the **Sukhdev Thapar Memorial in Ludhiana** and the National Martyrs' Memorial should be coupled with **public-history programming** — primary-source archives, oral histories, accessible scholarship — so that the next generation engages substantively.
Mains Q · 250w'Revolutionary nationalism did not run counter to mass civil disobedience; it deepened it.' Examine this proposition with reference to the role of Sukhdev Thapar and the HSRA in India's freedom struggle. (15 marks, 250 words)
Q1. Which of the following best describes the legal character of the 'Lahore Conspiracy Case' under which Bhagat Singh, Sukhdev and Rajguru were tried?
- A.A trial before a special tribunal constituted under a colonial ordinance, with curtailed defence rights and no right of appeal to the Privy Council on most issues
- B.A regular sessions trial under the Indian Penal Code with full appellate rights up to the Privy Council
- C.A purely military court-martial under British Army regulations
- D.A Federal Court reference under the Government of India Act, 1935
tap to reveal answer
Answer: A. A trial before a special tribunal constituted under a colonial ordinance, with curtailed defence rights and no right of appeal to the Privy Council on most issues
The Lahore Conspiracy Case was tried by a special tribunal set up under a colonial ordinance that curtailed normal defence rights and the trial was completed in the accused's absence at one stage. It was not a regular sessions trial, nor a court-martial, nor a Federal Court matter (the 1935 Act came later).
