The Forward Bloc was a political party formed by Subhas Chandra Bose in 1939, advocating complete independence from British rule. It aimed to unite all anti-British forces under a single banner. The party supported socialist principles and opposed both British imperialism and the dominant Congress Party.

During World War II, Bose formed the Indian National Army (INA) with the support of the Japanese, aiming to free India from British rule. The INA consisted of Indian prisoners of war and civilians in Southeast Asia. The INA’s formation and activities had a significant impact on the Indian independence movement, inspiring nationalist sentiment and challenging British authority.

However, the INA’s military campaigns were largely unsuccessful, and with Japan’s defeat in the war, the INA also faced defeat. Despite this, the INA’s legacy remained strong, and its members were hailed as heroes in India. The trials of INA officers after the war, particularly the Red Fort Trials, further fueled nationalist sentiments and contributed to the eventual independence of India in 1947.
