Origins By 1902, Kolkata (formerly Calcutta) had three secret societies working toward the violent overthrow of British rule in India: one founded by Calcutta student Satish Chandra Basu with the patronage of Calcutta barrister
Pramatha Mitra, another led by
Sarala Devi, and the third founded by
Aurobindo Ghose. Ghose and his brother
Barin were among the strongest proponents of militant Indian nationalism at the time. Nationalist writings and publications by Aurobindo and Barin, including
Bande Mataram and
Jugantar Patrika (Yugantar), had a widespread influence on Bengal youth and helped Anushilan Samiti to gain popularity in Bengal. The
1905 partition of Bengal stimulated radical nationalist sentiments in Bengal's
Bhadralok community, helping the Samiti to acquire the support of educated, politically conscious and disaffected members of local youth societies. The Samiti's program emphasised physical training, training its recruits with daggers and lathis (bamboo staffs used as weapons). The
Dhaka branch was led by
Pulin Behari Das, and branches spread throughout East Bengal and Assam. More than 500 branches were opened in
Eastern Bengal and Assam, linked by "close and detailed organisation" to Pulin's headquarters at Dhaka. This branch soon overshadowed its parent organisation in Calcutta. Branches of Dhaka Anushilan Samiti emerged in
Jessore,
Khulna,
Faridpur,
Rajnagar, Rajendrapur, Mohanpur, Barvali and Bakarganj, with an estimated membership of 15,000 to 20,000. Within two years, Dhaka Anushilan changed its aims from those of the
Swadeshi movement to that of political terrorism. The organisation's political views were expressed in the journal
Jugantar, founded in March 1906 by
Abhinash Bhattacharya, Barindra,
Bhupendranath Dutt and
Debabrata Basu. It soon became an organ for the radical views of Aurobindo and other Anushilan leaders, and led to the Calcutta Samiti group being dubbed the "Jugantar party". Early leaders were
Rash Behari Bose,
Bhavabhushan Mitra,
Jatindranath Mukherjee and
Jadugopal Mukherjee. In December 1907, the Bengal branch derailed a train carrying Bengal Lieutenant Governor
Andrew Henderson Leith Fraser in a plot led by the Ghosh brothers. In the same month, the Dhaka Anushilan Samiti assassinated former Dhaka district magistrate D. C. Allen. The following year, the Samiti engineered eleven assassinations, seven attempted assassinations and explosions and eight dacoities in West Bengal. Their targets included British police officials and civil servants, Indian police officers, informants, public prosecutors of political crimes, and wealthy families. Under Barin Ghosh's direction, the Samiti's members also attempted to assassinate French colonial officials in
Chandernagore who were seen as complicit with the Raj. Anushilan Samiti established early links with foreign movements and Indian nationalists abroad. In 1907
Hem Chandra Kanungo (Hem Chandra Das) went to Paris by selling his land property to learn bomb-making from Nicholas Safranski, a Russian revolutionary in exile. Nandalal Bannerjee (the officer who arrested Khudiram) was shot and killed in 1908, followed by the assassinations of the prosecutor and informant for the Alipore case in 1909. After Aurobindo's retirement, the western Anushilan Samiti found a more prominent leader in
Bagha Jatin and emerged as the
Jugantar. Jatin revitalised links between the central organisation in Calcutta and its branches in
Bengal,
Bihar,
Orissa and
Uttar Pradesh, establishing hideouts in the
Sunderbans for members who had gone underground. The group slowly reorganised, aided by
Amarendra Chatterjee,
Naren Bhattacharya and other younger leaders. Some of its younger members, including
Taraknath Das, left India. Over the next two years, the organisation operated under the cover of two apparently-separate groups: Sramajeebi Samabaya (the Labourer's Cooperative) and S.D. Harry and Sons. Around this time Jatin attempted to establish contacts with the
10th Jat Regiment, garrisoned at
Fort William in Calcutta, and Narendra Nath committed a number of robberies to raise money. Shamsul Alam, a Bengal police officer preparing a conspiracy case against the group, was assassinated by Jatin associate Biren Dutta Gupta. His assassination led to the arrests which precipitated the
Howrah-Sibpur Conspiracy case. In 1911, Dhaka Anushilan members shot dead Sub-inspector Raj Kumar and Inspector Man Mohan Ghosh, two Bengali police officers investigating unrest linked to the group, in
Mymensingh and
Barisal. This was followed by the assassination of
CID head constable Shrish Chandra Dey in Calcutta. In February 1911, Jugantar bombed a car in Calcutta, mistaking an Englishman for police officer Godfrey Denham.
Rash Behari Bose (described as "the most dangerous revolutionary in India") extended the group's reach into
North India, where he found work in the Indian Forest Institute in
Dehra Dun. Bose forged links with radical nationalists in
Punjab and the
United Provinces, including those later connected to
Har Dayal. During the 1912 transfer of the imperial capital to New Delhi, Viceroy
Charles Hardinge's
howdah was bombed by a member of the Samiti,
Basanta Kumar Biswas; his
mahout was killed, and Hardinge was seriously injured.
World War I , wounded after his final battle on the banks of Burha Balang off
Balasore. As war between Germany and Britain began to seem likely, Indian nationalists at home and abroad decided to use the war for the nationalist cause. Through Kishen Singh, the Bengal Samiti cell was introduced to
Har Dayal when Dayal visited India in 1908. Dayal was associated with India House, then headed by V. D. Savarkar. By 1910, Dayal was working closely with Rash Behari Bose. After the decline of India House, Dayal moved to San Francisco after working briefly with the
Paris Indian Society. Nationalism among Indian immigrants (particularly students and the working class) was gaining ground in the United States. Taraknath Das, who left Bengal for the United States in 1907, was among the Indian students who engaged in political work. In California, Dayal became a leading organiser of Indian nationalism amongst predominantly-Punjabi immigrant workers and was a key member of the
Ghadar Party. With
Naren Bhattacharya, Jatin met the crown prince of Germany during the latter's 1912 visit to Calcutta and obtained an assurance that arms and ammunition would be supplied to them. Jatin learned about Bose's work from
Niralamba Swami on a pilgrimage to
Brindavan. Returning to Bengal, he began reorganising the group. Bose went into hiding in
Benares after the 1912 attempt on Hardinge but he met Jatin towards the end of 1913, outlining prospects for a pan-Indian revolution. In 1914 Bose, the Maharashtrian
Vishnu Ganesh Pingle and Sikh militants planned simultaneous troop uprisings for February 1915. In Bengal, Anushilan and Jugantar launched what has been described by historians as "a reign of terror in both the cities and the countryside ... [which] ... came close to achieving their key goal of paralysing the administration". An atmosphere of fear severely affected morale in both the police and courts. In August 1914, Jugantar seized a large amount of arms and ammunition from the
Rodda company, a Calcutta arms dealer, and used them in robberies in Calcutta for the next two years. In 1915, only six revolutionaries were successfully tried. Both the February 1915 plot and a December 1915 plot were thwarted by British intelligence. Jatin and a number of fellow revolutionaries were killed in a firefight with police at
Balasore, in present-day Orissa, which brought Jugantar to a temporary end. The
Defence of India Act 1915 led to widespread arrests, internments, deportations and executions of members of the revolutionary movement. By March 1916, widespread arrests helped Bengal police crush the
Dacca Anushilan Samiti in Calcutta. Regulation III and the Defence of India Act were enforced throughout Bengal in August 1916. By June 1917, 705 people were under house arrest under the Act and 99 were imprisoned under Regulation III. According to official lists, 186 revolutionaries were killed or convicted by 1918. After the war, the Defence of India Act was extended by the
Rowlatt Act, the passage of which was a prime target of the protests of
M. K. Gandhi's non-cooperation movement. Many revolutionaries released after the war escaped to Burma to avoid repeated incarceration.
After the war The first non-cooperation movement, the
Rowlatt Satyagrahas led by Gandhi, was active from 1919 to 1922. It received widespread support from prominent members of the Indian independence movement. In Bengal, Jugantar agreed to a request by
Chittaranjan Das (a respected leader of the Indian National Congress) to refrain from violence. Although Anushilan Samiti did not adhere to the agreement, it sponsored no major actions between 1920 and 1922. During the next few years, Jugantar and the Samiti became active again. The resurgence of radical nationalism linked to the Samiti during the 1920s led to the passage of the Bengal Criminal Law Amendment Ordinance in 1924. The act restored extraordinary powers of detention to the police; by 1927 more than 200 suspects were imprisoned under the act, including
Subhas Chandra Bose, curtailing the resurgence of nationalist violence in Bengal. However, soon afterwards, in 1934, the revolutionary movement in Bengal ended. A large portion of the Samiti movement was attracted to left-wing politics during the 1930s, and those who did not join left-wing parties identified with Congress and the
Congress Socialist Party. During the mass detentions of the 1930s surrounding the civil-disobedience movement, many members joined Congress. Jugantar was formally dissolved in 1938; many former members continued to act together under Surendra Mohan Ghose, who was a liaison between other Congress politicians and Aurobindo Ghose in Pondicherry. During the late 1930s, Marxist-leaning members of the Samiti in the CSP announced the formation of the
Revolutionary Socialist Party (RSP). ==Organisation==
