Jugantar Party was the leading revolutionary terrorist group in colonial Bengal. An inner circle within the Calcutta anushilan samiti under barindra kumar ghosh and Bhupendranath Datta (with the advice of aurobindo ghosh) started the weekly Jugantar (New Era) in April 1906. The group is named after the Jugantar, the mouthpiece of the advocates of militant nationalism. Barindra vowed to free India from the British colonial domination with religious inspiration tempered by acts of violence, justifying murders by Ksatriyas to further happiness of mankind. He launched a vigorous anti-Partition movement with a revolutionary zeal. He and his twenty-one followers collected arms and explosives and manufactured bombs and thus laid the foundation of the terrorist group, called the Jugantar. Its Head Quarters was located at 93/a Baubazar Street. Senior figures among the first revolutionary generation, notably Hemchandra Qanungo, went abroad to get both political and military training. Hemchandra obtained the training from a Russian E9migrE9 in Paris. Returning home in January 1908, he set up a combined religious school and bomb factory at a garden house in Maniktala suburb of Calcutta. But the group was arrested within hours of the Kennedy murders (30 April 1908) by kshudiram basu.
