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.
Narayan Sanyal (politician)
Sanyal was initially associated with the Man-Money-Gun group founded by Bengali revolutionary Ananta Singh, until the Naxalbari uprising erupted in 1967. In 1969 he went to Bihar and started working under Satyanarayan Singh, the then politburo member of CPI(ML). When almost the entire Bihar state committee defected under Singh’s leadership in 1971 over differences with Charu Majumdar ideology, Sanyal led pro-Majumdar unit of CPI(ML) in Bihar and organized members in the Jehanabad - Palamu belt. He was arrested in 1973 and was released in 1977 after the first Left Front government released political prisoners. In 1978, Sanyal along with others formed the group named CPI(ML) Party Unity. He became the general secretary of that group in 1987. This group was merged with CPI(ML)(People’s War) in 1998. While he was working in Bastar region in Chhattisgarh, played a pivotal role of merger with unified Communist Party of India (Marxist–Leninist) People's War and Maoist Communist Centre of India (MCC) in 2004. He also became politburo member of Communist Party of India (Maoist). Sanyal was also active in Palamu region of Jharkhand.
