Explanation:

It was a Bengali Indian organisation and arose from conglomerations of local youth groups and gyms in Bengal. It had two prominent if somewhat independent arms in East and West Bengal identified as Dhaka Anushilan Samiti and the Jugantar group respectively. Between its foundations to its gradual dissolution through 1930s, the Samiti collaborated with other revolutionary organisations in India and abroad. Led by notable revolutionaries of the likes of Aurobindo Ghosh, Rash Behari Bose and Jatindranath Mukherjee, the Samiti was involved in a number of noted incidences of revolutionary terrorism against British interests and administration in India. These included the early attempts to assassinate Raj officials, the 1912 attempt on the life of Viceroy of India, as well as the Sedetious conspiracy during World War I.
