Early years Narendra Nath "Naren" Bhattacharya was born on 21 March 1887 in Arbelia,
North 24 Parganas,
West Bengal, near
Calcutta (Kolkata). The Bhattacharyas were
Sakta Brahmins – a family of hereditary priests. Roy's paternal grandfather was the head priest of the goddess
Kheputeswari in the village of Kheput,
Midnapore district. The couple had a total of eight children, including the fourth-born Naren. According to one biographer, Roy agreed with Bankim that true religion was not being cloistered from the world, but working actively for the public good. Vivekananda reinforced this and advanced the idea that
Hinduism and Indian culture were superior to anything the Western world could offer. He formed a
rationalist group with his cousin Hari Kumar Chakravarti (1882–1963). Members included Satkori Banerjee (Bandhopadhyay), brothers Saileshvar and Shyamsundar Bose, Roy's cousins Phani and Narendra Chakravarti, and
Mokshadacharan Samadhyayi, an organiser of the
Anushilan Samiti in
Chinsura. In July 1905, the
partition of Bengal was announced, scheduled to take effect in October. A mass movement aimed at annulling the partition emerged, giving radical nationalists like Roy an opportunity to build broader support. Following his high school expulsion for organising a meeting and a march against the partition, Roy and Chakravarti moved to Kolkata and joined the Anushilans. Barin sent
Prafulla Chaki with Charuchandra Datta to see
Bagha Jatin at
Darjeeling who was posted there on official duty, and do away with the Lt. Governor. On explaining to Prafulla that it was not the right time, Jatin promised to contact him later. Though Prafulla was impressed by him, Barin cynically commented that it would be too much effort for a government officer to serve a patriotic cause. Phani returned from Darjeeling and, fascinated by Jatin's charisma, he informed his friends about him. On hearing Barin censuring Phani for disloyalty, Roy decided to meet Dada but was caught by Barin. The
Howrah-Shibpur Trial (1910–11) brought Bhattacharya closer to Jatindra Mukherjee. He also worked closely with
Hemchandra Kanungo for a during his time in the
Anushilan Samiti at
Calcutta, he was inspired by Kanungo's travels in
Europe, and he was also impressed by the advanced bomb manufacturing technologies that Hem had brought from
Russia.
The Hindu-German conspiracy Many Indian nationalists, including Roy, became convinced that only through a revolution would they be able to achieve India's independence from the
British Empire. So revolutionary nationalists looked to a rival imperial power, that of
Kaiser Wilhelm's Germany, as a potential source for funds and weapons. In August 1914,
World War I began, affecting both the UK and Germany. Expatriate Indian nationalists organised as the Indian Revolutionary Committee in
Berlin made an informal appeal to the
German government to support a revolution in India. Towards the end of the year, the Germans had agreed to provide funding and material to start an uprising against British rule. Roy would not see his homeland again for 16 years. Disgusted but still holding out hope, Roy left Indonesia for
Japan, hoping to win Japanese support for their cause, despite Japan's
nominal alliance with Great Britain. Efforts to raise money from the German Ambassador to China were likewise unsuccessful. Roy's activities soon drew the attention of the Japanese
secret police. He tried to make his way to
Peking (Beijing), but he was identified by the British authorities, who detained him. However, he was able to escape jail time due to the British Consul General's ill ease with holding a British subject indefinitely without formal charges. Efforts to raise funds from the German consulate at Hankow resulted in a tentative agreement. However, this plan also failed due to the scale of the commitment, which had to be approved in Berlin according to Admiral
Paul von Hintze. Roy decided to search for German funding from the German Ambassador in the United States, before heading to Germany. In an effort to throw the British off his trail, and in an effort to obtain more suitable accommodations for the long trans-Pacific voyage, Roy disembarked from
Kobe, Japan. In Kobe, he used a fake French-Indian passport previously obtained for him by the Germans in China. Posing as a seminary student bound for Paris, Roy obtained an American visa, bought a ticket, and sailed for San Francisco. ==Communist movement (1910s–1929)==
