Dhaka Anushilan Samiti
Dhaka Anushilan Samiti was a branch of the Anushilan Samiti founded in the city of Dhaka in November 1905. Initially a group of eighty under the leadership of Pulin Behari Das, it "spread like wildfire" throughout the province of East Bengal. More than 500 branches were opened, linked by a "close and detailed organization" to Pulin’s headquarters at Dhaka. It absorbed smaller groups in the province and soon overshadowed its parent organisation in Calcutta. Branches of Dhaka Anushilan emerged in the towns of Jessore, Khulna, Faridpur, Rajnagar, Rajendrapur, Mohanpur, Barvali, Bakarganj and other places. Estimates of Dhaka Anushilan Samiti's reach show a membership of between 15,000 and 20,000 members. Within another two years, Dhaka Anushilan would devolve its aims from the Swadeshi to the dedicated aim of political terrorism. The "Dhaka Anushilan Samiti" embarked on a radical program of political terrorism. It broke with the "Jugantar group" due to differences with Aurobindo's approach of slowly building a base for a revolution with a mass base. The Dhaka group saw this as slow and insufficient, and sought immediate action and result. It was responsible for a number of political assassinations, most notably the murder of D.C. Allen. However, it reached a temporary halt after the arrest and deportation of Pulin Das and the Barisal Conspiracy Case in 1913. Dhaka Anushilan decided not to participate in the German plot of World War I. After the war, it continued in its violent movement, and some of its members went on to form the Neo-violence group.
Indian independence movement
Within a short time of its inception, these organisations became the focus of an extensive police and intelligence operations. Operations against "Anushilan Samiti" saw founding of the Special branch of Calcutta Police. The intelligence operations against India House saw the founding of the Indian Political Intelligence Office which later grew to be the Intelligence bureau in independent India. Heading the intelligence and missions against Ghadarite movement and India revolutionaries was the MI5(g) section, and at one point invokved the Pinkerton's detective agency. Notable officers who led the police and intelligence operations against Indian revolutionaries, or were involved in it, at various time included John Arnold Wallinger, Sir Robert Nathan, Sir Harold Stuart, Vernon Kell, Sir Charles Stevenson-Moore and Sir Charles Tegart, as well as W. Somerset Maugham. The threat posed by the activities of the "Samiti" in Bengal during World War I, along with the threat of a Ghadarite uprising in Punjab, saw the passage of Defence of India Act 1915. These measures saw the arrest, internment, transportations and execution of a number of revolutionaries linked to the organisation, and was successful in crushing the East Bengal Branch. In the aftermath of the war, the Rowlatt committee recommended extending the Defence of India Act (as the Rowlatt act) to thwart any possible revival of the "Samiti" in Bengal and the Ghadarite movement in Punjab. In the 1920s, Alluri Sitarama Raju led the ill-fated Rampa Rebellion of 1922–24, during which a band of tribal leaders and other sympathisers fought against the British Raj. He was referred to as "Manyam Veerudu" ("Hero of the Jungles") by the local people. After the passing of the 1882 Madras Forest Act, its restrictions on the free movement of tribal peoples in the forest prevented them from engaging in their traditional "podu" (Slash-and-burn) agricultural system, which involved shifting cultivation. Raju led a protest movement in the border areas of the Godavari Agency in Madras Presidency (present-day Andhra Pradesh). Inspired by the patriotic zeal of revolutionaries in Bengal, Raju raided police stations in and around Chintapalle, Rampachodavaram, Dammanapalli, Krishna-devi-peta, Rajavommangi, Addateegala, Narsipatnam and Annavaram. Raju and his followers stole guns and ammunition and killed several British army officers, including Scott Coward near Dammanapalli. The British campaign lasted for nearly a year from December 1922. Raju was eventually trapped by the British in the forests of Chintapalli then tied to a tree and shot dead with a rifle.
