The rise of militarism in India dates back to the British Raj with the establishment of several Indian independence movement organizations such as the Indian National Army led by Subhas Chandra Bose. The Indian National Army (INA) played a crucial role in pressuring the British Raj after it occupied the Andaman and Nicobar Islands with the help of Imperial Japan, but the movement lost momentum due to lack of support by the Indian National Congress, the Battle of Imphal, and Bose's sudden death.
