Anushilan Samiti
Anushilan Samiti (Ōnūshīlōn sōmītī, "lit": body-building society) was a Bengali Indian organisation that existed in the first quarter of the twentieth century, and propounded revolutionary violence as the means for ending British rule in India. The organisation arose from a conglomeration of local youth groups and gyms ("Akhara") in Bengal in 1902. It had two prominent, if somewhat independent, arms in East and West Bengal identified as Dhaka Anushilan Samiti centred in Dhaka (modern day Bangladesh), and the Jugantar group (centred at Calcutta) respectively.

In the aftermath of the Manicktala conspiracy, 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. Between 1909 and 1914, the group continued its campaign against the interests, making a number of attempts on the lives of Raj officials with variable successes. In a concerted attempt of revenge, Ashutosh Biswas, an advocate of Calcutta High Court in charge of the prosecution of the Gossain murder case, was shot dead within Calcutta High Court in 1909. In 1910, Shamsul Alam, Deputy Superintendent of Bengal Police responsible for investigating the Alipore Bomb case, was shot dead on the steps of Calcutta High Court. Naren Bannerjee, the police officer who arrested Kshudiram Bose, was murdered in 1910. These assassinations led up to the uncovering of Jatin's network, precipitating the Howrah-Sibpur Conspiracy case. Undeterred, the Samiti's networks continued the attempts on political violence and assassinations, using its base in Chandernagore. The most notable was the attempt on the life of Viceroy of India in 1912 in a conspiacy headed by Rash Behari Bose. However, the most serious threat organised by the Samiti arose in 1914 when, with the clouds of war gathering in Europe in 1914, the Samiti began liaising with revolutionary groups abroad and with Imperial Germany to overthrow the British Raj with a Pan-Indian Mutiny.
