The Kakori Conspiracy and the HRA/HSRA

From a night train near Lucknow in 1925 to the Lahore gallows in 1931: how the Hindustan Republican Association turned socialist, who did what, and the dates examiners swap.

🎯 What you'll learn
  • Why the revolutionary movement revived after Chauri Chaura and what the HRA stood for
  • What happened at Kakori, who was tried, and who was hanged on which day
  • How the HRA became the HSRA in 1928 and what Saunders, the Assembly bomb and the Lahore case mean
  • The Philosophy of the Bomb, Jatin Das, 23 March 1931 and the traps UPSC sets

Every year on 19 December the country remembers the Kakori martyrs' Balidan Diwas. On that day in 1927, Ram Prasad Bismil was hanged at Gorakhpur, Ashfaqulla Khan at Faizabad and Roshan Singh at Allahabad. The fourth man, Rajendra Lahiri, had been hanged two days earlier at Gonda. All four belonged to the Hindustan Republican Association (HRA), and their crime was stopping a train. For a defence-exam candidate the story matters because it is the bridge between two revolutionary generations: the Bengal groups of 1902-1915 and the Punjab and United Provinces young men of 1928-1931, who added socialism to the gun. UPSC asks it as a chain of organisations, dates and authors.

After Chauri Chaura: Why the Gun Came Back

By Narendra Singh · GS faculty, The Cavalier · 15 years teaching GS

In February 1922 a crowd at Chauri Chaura burnt a police station, and Gandhi called off the Non-Cooperation Movement. Young men who had left their colleges at his call were left with no programme, and many concluded that non-violence had failed. Our page on the Gandhian national movement covers the mass phase that this one follows.

The new current had a different centre from the Bengal societies of before 1915 (see Anushilan and Jugantar). It ran through the United Provinces, Punjab and Delhi. A key text was Bandi Jivan ("A Life of Captivity", 1922), the memoir of Sachindranath Sanyal, a veteran of the Ghadar-era conspiracies. Its pages inspired many of the young men who followed him.

After an all-India conference of revolutionaries at Kanpur, the Hindustan Republican Association was founded in October 1924 to organise an armed revolution. Sanyal, Ram Prasad Bismil and Jogesh Chandra Chatterjee were its leading organisers, and Ashfaqulla Khan, Rajendra Lahiri and Roshan Singh joined soon after. Its aim was a federal republic of the United States of India, and its aim was social too: an end to the exploitation of man by man. In the first days of January 1925 the HRA distributed a printed manifesto titled "The Revolutionary", written mainly by Sanyal, in cities across northern India. It set out the aim of a federal republic and spoke of ending every system that lets one person exploit another. That social aim is why historians treat the HRA as a step towards the later socialism of the HSRA.

Like every underground party, the HRA needed money for arms. Seizing government cash was the decision that led to Kakori.

Kakori, 9 August 1925: The Train Action

On the night of 9 August 1925, a party of about ten HRA members stopped the Number 8 Down train, which was travelling from Shahjahanpur to Lucknow, near the small station of Kakori, a few miles from Lucknow. One of them pulled the alarm chain. The group overpowered the guard and took the bags of government cash. The planners were Ram Prasad Bismil and Ashfaqulla Khan, and the party included Rajendra Lahiri, Chandrashekhar Azad, Sachindra Bakshi, Manmath Nath Gupta and others. A passenger was killed by a stray shot, which made it a murder case.

Within weeks the police had arrested much of the HRA. About forty people were tried before a special court at Lucknow from May 1926. The sessions court gave its verdict on 6 April 1927, and the Chief Court upheld the death sentences on four men in August. As Bipan Chandra puts it, seventeen were given long terms of imprisonment, four were transported for life and four, including Bismil and Ashfaqulla, were hanged.

Chandrashekhar Azad was never arrested. He had joined the movement as a teenager after being whipped by a magistrate for his part in Non-Cooperation, and he gave his name as "Azad" (free) in court. He escaped, rebuilt the shattered HRA and became its military leader.

Sachindranath Sanyal, who had founded the party, was not at Kakori. He had been arrested earlier for the manifesto, was charged in the Kakori case as well, and was sentenced to transportation for life. The HRA's top layer was thus gone in a single blow.

Three traps on Kakori

1. Surya Sen is Chittagong (1930, Bengal), not Kakori. CAPF 2019 used him as the odd name out (see the past papers below). 2. Kakori was a train action to raise funds for a political party, not a private robbery, which is why it is remembered as a political act and not as a crime. 3. Kakori's men were hanged in December 1927; Bhagat Singh, Sukhdev and Rajguru in March 1931. Different men, three and a half years apart.

1928: The Association Turns Socialist

The HRA had almost no leaders left. Azad, with younger recruits from Punjab, and above all Bhagat Singh and Sukhdev from the Naujawan Bharat Sabha at Lahore, took over the work. On 8-9 September 1928 revolutionaries from the United Provinces, Punjab, Rajasthan and Bihar met in the ruins of Feroz Shah Kotla, Delhi. They renamed the party the Hindustan Socialist Republican Association (HSRA). Chandrashekhar Azad became its commander-in-chief. The word "Socialist" was the point of the meeting, and Bhagat Singh was its main advocate. The renaming recorded the socialist turn that Bipan Chandra notes among the young revolutionaries.

The Simon Commission reached India in February 1928 and was met with a country-wide hartal. At Lahore, on 30 October 1928, police lathi-charged a procession led by Lala Lajpat Rai, who died on 17 November 1928. The HSRA decided that the insult to the "Lion of Punjab" had to be answered. On 17 December 1928, Bhagat Singh and Rajguru shot John Saunders, an assistant superintendent of police, outside the police headquarters in Lahore, with Azad covering their escape. The intended target is usually named as Scott, the officer who had ordered the lathi charge, and Saunders was shot by mistake. Posters next morning accepted responsibility, regretting the loss of a life but calling the officer part of an unjust order.

1929: The Assembly Bomb, the Court and the Philosophy of the Bomb

On 8 April 1929, Bhagat Singh and Batukeshwar Dutt threw two bombs into the Central Legislative Assembly in Delhi, onto empty benches, as the Public Safety Bill and Trade Disputes Bill were being discussed. They shouted "Inquilab Zindabad" and threw leaflets. The bombs had been made deliberately harmless. The leaflet said that the aim was not to kill but to make the deaf hear. Both men could have escaped and chose to be arrested, so that they could use the trial as a platform for their ideas.

The trial changed the HSRA's public image. Police traced the bomb workshops and the Saunders connection, and the government began the Lahore Conspiracy Case against Bhagat Singh, Sukhdev, Rajguru and others. In jail the prisoners demanded the treatment due to political prisoners, such as proper food, books and newspapers, and went on hunger strike. Jatin Das (Jatindranath Das), a young man who had advised the group on explosives, died on 13 September 1929 after a fast of about 63 days. His funeral procession drew huge crowds, and his death moved the public more than any speech.

The HSRA also took part in a public debate. After an attempt to blow up the Viceroy's train in December 1929, Gandhi wrote an article called "The Cult of the Bomb" in Young India, criticising revolutionary violence. The HSRA replied with a manifesto, "The Philosophy of the Bomb", written by Bhagwati Charan Vohra and issued in the HSRA's name. It argued that the bomb was a means to wake an unarmed country and that the aim was a revolution of the masses. Vohra died in May 1930 while testing a bomb on the bank of the Ravi. In 1930 Bhagat Singh also wrote the essay "Why I Am an Atheist" in jail.

1931: The Last Chapter

The tribunal gave its verdict on 7 October 1930, and Bhagat Singh, Sukhdev and Rajguru were hanged at Lahore on 23 March 1931. The Gandhi-Irwin Pact had been signed on 5 March, and many Indians expected Gandhi to win a commutation. He pleaded with the Viceroy for it but could not make it part of the pact. The Congress session at Karachi, held days after the executions under Sardar Patel, paid tribute to the courage of the three while keeping its distance from their methods. Bipan Chandra records that the three wrote a few days earlier that the final battle would begin very soon, and affirmed their faith in socialism in their last letters.

A month earlier, on 27 February 1931, Chandrashekhar Azad was surrounded by police at Alfred Park, Allahabad. He fought until his last bullet and shot himself, keeping his vow never to be taken alive. With Azad dead and the other leaders hanged or in jail, the HSRA ended. The Chittagong Armoury Raid of April 1930 under Surya Sen was a separate conspiracy, not part of the HSRA.

The whole chain in order

Chauri Chaura (Feb 1922) → HRA (Oct 1924) → "The Revolutionary" (Jan 1925) → Kakori (9 Aug 1925) → hangings (17/19 Dec 1927) → HSRA (Sep 1928) → Saunders (17 Dec 1928) → Assembly bomb (8 Apr 1929) → Jatin Das (13 Sep 1929) → Azad dies (27 Feb 1931) → Bhagat Singh, Sukhdev, Rajguru hanged (23 Mar 1931).

The revolutionaries won no military victory. What they changed was the tone of Indian politics: their courtroom defiance exposed the regime's harshness, and their open socialism put land and labour on the nationalist agenda. In the 1930s the Congress Socialist Party (1934) and Nehru's call for socialism at the 1936 Lucknow session carried the same current into the Congress itself. For the broader sweep, from the 1857 aftermath to the Azad Hind Fauj, see our page on the revolutionary struggle and the INA.

How UPSC Has Asked It: Past Papers Solved

These are real questions from UPSC papers. CDS and NDA ask about this strand in short factual forms: who wrote it, who founded it, which date. Two of the questions below are from the CAPF paper, which draws on the same syllabus.

CDS 2023-I · Q29

Who among the following is the author of the book Bandi Jivan?

(a) Rash Behari Bose   (b) Veer Savarkar   (c) Aruna Asaf Ali   (d) Sachindranath Sanyal

Answer: (d). Sanyal also co-founded the HRA. Rash Behari Bose and Savarkar belong to the earlier phase.

CAPF 2019 · Paper I · Q22

Who among the following was NOT associated with the Kakori Conspiracy Case

(a) Ramprasad Bismil   (b) Rajendra Lahiri   (c) Ashfaqulla Khan   (d) Surya Sen

Answer: (d). Surya Sen led the Chittagong Armoury Raid of 1930 in Bengal. The other three were Kakori men hanged in December 1927.

Bhagat Singh threw a bomb in the Central Legislative Assembly in 1929 with the objective to kill as many people as possible.

(a) 1 and 3   (b) 2 and 3   (c) 2 only   (d) 3 only

Answer: (d). Statements 1 and 2 are true. Statement 3 is false: the bombs were made harmless, were thrown on empty benches and were meant to "make the deaf hear".

CDS 2019-II · Q29

What was the Dutt-Bradley thesis?

(a) The Working Committee of the Indian National Congress decided that Congress should play a crucial role in realising the independence of India   (b) The Socialist party decided to play foremost part in anti-imperialist struggle   (c) Revolutionary socialist Batukeshwar Dutt put forth a ten-point plan to work for the success of anti-imperialist front   (d) It was a Communist party document, according to which the National Congress could play a great part and a foremost part in realising the anti-imperialist people's front

Answer: (d). The thesis (1936) was drawn up by the Communists R. Palme Dutt and Ben Bradley. Option (c) is the trap: it borrows the name of Batukeshwar Dutt, who threw the Assembly bomb in 1929 and had nothing to do with it.

Pattern in the questions

Examiners test authorship (Vohra, Sanyal), odd-one-out across regions (Surya Sen for Bengal, Kakori for UP) and twin names (the two Dutts; Hindustan Republican vs Hindustan Socialist Republican).

Frequently asked questions

What was the Kakori conspiracy?

On 9 August 1925, members of the Hindustan Republican Association stopped the Number 8 Down train near Kakori, close to Lucknow, and took the government cash it carried. The government arrested about forty people and tried them in the Kakori Conspiracy Case. Four of them, Ram Prasad Bismil, Ashfaqulla Khan, Roshan Singh and Rajendra Lahiri, were hanged in December 1927.

What is the difference between the HRA and the HSRA?

The Hindustan Republican Association was founded in 1924 at Kanpur to win a federal republic by armed revolution. In September 1928 at Feroz Shah Kotla in Delhi it was reorganised as the Hindustan Socialist Republican Association, with Chandrashekhar Azad as commander-in-chief and an explicit socialist aim. Bhagat Singh and Sukhdev were its best-known younger leaders.

Why did Bhagat Singh throw a bomb in the Central Legislative Assembly?

On 8 April 1929, Bhagat Singh and Batukeshwar Dutt threw harmless bombs on empty benches to protest against repressive laws such as the Public Safety Bill. They wanted to make the deaf hear, and they chose to be arrested so that they could use the court as a platform for their ideas.

Who wrote The Philosophy of the Bomb?

Bhagwati Charan Vohra wrote it as the HSRA's reply to Gandhi's article "The Cult of the Bomb". It defended revolutionary violence as a means of waking the country and presented the aim as a revolution of the masses. Vohra died in 1930 while testing a bomb.

When were Bhagat Singh, Sukhdev and Rajguru executed, and how is that different from the Kakori hangings?

Bhagat Singh, Sukhdev and Rajguru were hanged at Lahore on 23 March 1931 after the Lahore Conspiracy Case, which was linked to the Saunders killing. The Kakori men were hanged in December 1927, three and a half years earlier, after a different trial in Lucknow.
