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.

The growth of the Indian middle class during the 18th century, amidst competition among regional powers and the ascendancy of the British East India Company, led to a growing sense of "Indian" identity. The refinement of this perspective fed a rising tide of nationalism in India in the last decades of the 1800s. Its speed was abetted by the creation of the Indian National Congress in India in 1885 by A.O. Hume. The Congress developed into a major platform for the demands of political liberalisation, increased autonomy and social reform. However, the nationalist movement became particularly strong, radical and violent in Bengal and, later, in Punjab. Notable, if smaller, movements also appeared in Maharashtra, Madras and other areas in the South. The movement in Maharshtra, especially Bombay and Poona preceded most revolutionary movements in the country. This movement, further, had the ideological, and by some suggestion covert but active, support of Bal Gangadhar Tilak. 1876 saw the foundation of The Indian Association in Calcutta under the leadership of Surendranath Banerjea. This organisation successfully drew into its folds students and the urban middle–class, for which it served as a mouthpiece. The Association became the mouthpiece of an informal constituency of students and middle-class gentlemen. It sponsored the Indian National Conference in 1883 and 1885, which later merged with the Indian National Congress. Calcutta was at the time the most prominent centre for organised politics, and some of the same students who attended the political meetings began at the time to organise "secret societies" which cultivated a cultural of physical strength and nationalist feelings.
