Part 1 — Foundations & Key Organisations

Introduction

Alongside the mainstream Indian National Congress-led constitutional and mass movements, a parallel stream of revolutionary nationalism ran through India's freedom struggle from the early 1900s until Independence in 1947. Revolutionaries believed that political freedom could not be won by petitions and prayers alone and turned to armed resistance, secret societies, propaganda, and individual acts of daring to awaken national consciousness and strike fear into the colonial administration. This note covers the major revolutionary organisations, leaders, incidents, and their regional spread — a high-yield area for SSC CGL, CHSL, MTS, and RRB NTPC/Group D General Awareness sections.

Background and Causes

Several factors gave rise to revolutionary nationalism in India:

The Partition of Bengal (1905) by Lord Curzon, ostensibly for administrative convenience but widely seen as a "divide and rule" tactic to split Hindus and Muslims, triggered the Swadeshi Movement and radicalised a generation of young Bengalis. The failure of moderate politics to secure concrete concessions from the British, and the growing influence of extremist leaders like Bal Gangadhar Tilak, Bipin Chandra Pal, and Lal Lajpat Rai (the Lal-Bal-Pal triumvirate), created fertile ground for more aggressive methods. Inspiration was also drawn from international revolutionary movements — the Irish Home Rule and Sinn Féin movements, the Russian nihilists and the 1905 Russian Revolution, Italian unification under Mazzini and Garibaldi, and later the Bolshevik Revolution of 1917. The repressive policies of the colonial state, including the Vernacular Press Act, Arms Act, and later the Rowlatt Act (1919), further alienated educated Indian youth.

Phase I: Early Revolutionary Activity (1900s–1910s)

Bengal — the Cradle of Revolutionary Nationalism

Bengal became the epicentre of early revolutionary activity following the 1905 partition.

Anushilan Samiti, founded in Calcutta in 1902 by Barrister Promotha Mitter, with Jatindranath Banerjee and later strongly shaped by Aurobindo Ghosh and his brother Barindra Kumar Ghosh, was among the earliest secret revolutionary societies. It combined physical culture (akhara-style training) with study of nationalist literature and bomb-making. A prominent offshoot, the Dhaka Anushilan Samiti, was led by Pulin Behari Das in East Bengal.

The Jugantar Party emerged as a breakaway/parallel group from Anushilan Samiti around 1906, associated with Barindra Ghosh, Bhupendranath Dutta (brother of Swami Vivekananda), and the Jugantar Patrika, a newspaper that openly advocated armed revolution.

The Alipore Bomb Case (1908) was a landmark trial following the Muzaffarpur conspiracy: revolutionaries Khudiram Bose and Prafulla Chaki attempted to assassinate the unpopular magistrate Kingsford but the bomb killed two British women instead. Prafulla Chaki shot himself to avoid capture; Khudiram Bose was hanged on 11 August 1908 at the age of 18, becoming one of the youngest martyrs of the freedom struggle. Aurobindo Ghosh was tried in the Alipore Bomb Case (defended by Chittaranjan Das) and acquitted; he subsequently withdrew from active politics to Pondicherry and turned to spiritual pursuits.

Other notable Bengal revolutionary acts include the killing of Public Prosecutor Ashutosh Biswas and the 1930 Chittagong Armoury Raid, covered separately below.

Punjab

The Ghadar Party (also spelt Ghadar/Gadar, meaning "revolt" or "mutiny") was founded in 1913 in San Francisco, USA, by Indian immigrants, primarily Punjabi Sikhs, under the leadership of Lala Hardayal, with Sohan Singh Bhakna as its first president. Its mouthpiece was the newspaper Ghadar. The party aimed to overthrow British rule through an armed uprising and called Indian revolutionaries and soldiers home at the outbreak of World War I, culminating in the failed 1915 Ghadar conspiracy. Kartar Singh Sarabha, executed at just 19, is remembered as a Ghadar martyr and inspired Bhagat Singh.

Maharashtra

Vinayak Damodar Savarkar founded Abhinav Bharat Society in 1904 in Nashik/Pune (originally as Mitra Mela), a secret revolutionary organisation with links to the India House in London. His book The Indian War of Independence 1857 reinterpreted the 1857 revolt as India's "First War of Independence" rather than a mere "mutiny." Madanlal Dhingra, associated with India House, assassinated Curzon Wyllie in London in 1909 and was hanged.

Damodar Hari Chapekar and his brothers assassinated W.C. Rand, the plague commissioner of Poona, in 1897 — often cited as one of the earliest revolutionary political assassinations in India, pre-dating the Bengal phase.

Phase II: Post-World War I and the Rise of Socialist Revolutionaries (1920s)

Hindustan Republican Association / Army (HRA)

Founded in October 1924 at Kanpur by Ram Prasad Bismil, Sachindra Nath Sanyal, Jogesh Chandra Chatterjee, and others, the HRA aimed to establish an independent federal republic of the United States of India through an organised armed revolution.

The Kakori Conspiracy/Train Robbery (9 August 1925) was the HRA's most famous action — a train carrying government treasury money between Shahjahanpur and Lucknow was looted near Kakori. Key participants included Ram Prasad Bismil, Ashfaqulla Khan, Rajendra Nath Lahiri, Thakur Roshan Singh, Chandrashekhar Azad, and Sachindra Nath Bakshi. Bismil, Ashfaqulla Khan, Roshan Singh, and Lahiri were hanged in December 1927; Chandrashekhar Azad evaded capture. Ram Prasad Bismil, also a poet, is remembered for the patriotic verse "Sarfaroshi ki Tamanna".

Hindustan Socialist Republican Association (HSRA)

The HRA was reorganised in 1928 at Feroz Shah Kotla, Delhi, as the Hindustan Socialist Republican Association (HSRA) under the leadership of Chandrashekhar Azad, with Bhagat Singh as a key ideologue, giving it an explicitly socialist orientation influenced by Marxism.

Bhagat Singh, along with Rajguru and Sukhdev, murdered J.P. Saunders (mistaking him for Superintendent Scott, who had ordered the lathi-charge that led to Lala Lajpat Rai's death) in Lahore in December 1928, avenging Lajpat Rai.

On 8 April 1929, Bhagat Singh and Batukeshwar Dutt threw non-lethal bombs into the Central Legislative Assembly in Delhi, shouting "Inquilab Zindabad" ("Long Live the Revolution"), to protest the Public Safety Bill and Trade Disputes Bill, and courted arrest deliberately to use the trial as a political platform.

Bhagat Singh, Sukhdev, and Rajguru were hanged on 23 March 1930 in Lahore Central Jail — the date is observed as Shaheed Diwas (Martyrs' Day). Chandrashekhar Azad, who vowed never to be captured alive, shot himself at Alfred Park, Allahabad, on 27 February 1931 during a police encounter; the park was later renamed Chandrashekhar Azad Park.

Chittagong Armoury Raid

On 18 April 1930, Surya Sen (Masterda) led a group including Ganesh Ghosh, Ambika Chakraborty, and the young Pritilata Waddedar and Kalpana Dutta in a raid on the Chittagong armoury in Bengal, aiming to seize weapons and cut communication lines. Pritilata Waddedar led an attack on the Pahartali European Club in 1932 and consumed cyanide to avoid capture. Surya Sen was captured in 1933 and hanged in January 1934.

Revolutionary Activity Abroad

Shyamji Krishna Varma founded India House in London in 1905 as a hub for Indian students and revolutionaries, and established the Indian Sociologist journal and the Indian Home Rule Society.

The Ghadar Party (covered above) operated from the USA and Canada.

The Berlin Committee (Indian Independence Committee), formed during World War I with German assistance, included Virendranath Chattopadhyay ("Chatto") and worked to organise anti-British activity abroad; it was linked to the broader Indo-German Conspiracy.

Rash Behari Bose, who had earlier been involved in the 1912 attempt to assassinate Viceroy Lord Hardinge in Delhi (the Delhi-Lahore Conspiracy), escaped to Japan and later played a key role in founding the Indian Independence League and the first Indian National Army (INA) in Southeast Asia in 1942, which he subsequently handed over to Subhas Chandra Bose in 1943.

Subhas Chandra Bose, after escaping house arrest in Calcutta in 1941 and travelling via Afghanistan and Germany to Southeast Asia, took command of the Azad Hind Fauj (INA) in 1943, gave the call "Tum Mujhe Khoon Do, Main Tumhein Azadi Doonga" ("Give me blood, I will give you freedom"), and established the Azad Hind Government (Provisional Government of Free India) in October 1943 with support from Japan. The INA fought alongside Japanese forces in the Imphal-Kohima campaign (1944) but was ultimately defeated. Bose is believed to have died in an air crash in Taiwan on 18 August 1945, though this remains a subject of historical debate.

Women in the Revolutionary Movement

Women played significant roles beyond Pritilata Waddedar and Kalpana Dutta. Bina Das attempted to assassinate Bengal Governor Stanley Jackson in 1932. Preetilata Waddedar was among the first women revolutionary martyrs. Durgawati Devi ("Durga Bhabhi") assisted Bhagat Singh's escape from Lahore after the Saunders killing. Kalpana Dutta later joined the Communist Party of India.

Ideological Strands

Revolutionary nationalism was not monolithic. Early revolutionaries (Anushilan Samiti, Abhinav Bharat) were influenced by cultural-religious nationalism, drawing on Hindu symbolism (goddess worship, the Bhavani Mandir concept associated with Aurobindo and Barindra Ghosh) alongside physical training akhadas. The later HSRA generation, especially Bhagat Singh, moved decisively towards secular socialism, influenced by Marxist-Leninist thought; Bhagat Singh's prison writings, including "Why I Am an Atheist", reflect this shift. Bose's INA represented a militarist, anti-colonial united-front approach, cutting across religious and regional lines under the slogan "Ittehad, Etemad, Qurbani" (Unity, Faith, Sacrifice).

Government Response and Repression

The colonial government responded with the Defence of India Act (1915), special tribunals, deportations under the Regulation III of 1818, and later the Rowlatt Act (1919), which allowed detention without trial and directly triggered the Jallianwala Bagh massacre (13 April 1919) under General Reginald Dyer, further radicalising Indian youth toward revolutionary methods. The Lahore Conspiracy Case (1929–30) tried Bhagat Singh, Sukhdev, and Rajguru; the Second Lahore Conspiracy Case tried others in the HSRA network.
