Subhas Chandra Bose in the context of "Axis powers"

A government-in-exile (GiE) is a political group that claims to be the legitimate government of a sovereign state or semi-sovereign state, but is unable to exercise legal power and instead resides in a foreign country. Governments in exile usually plan to one day return to their native country and regain formal power. A government in exile differs from a rump state in the sense that the latter controls at least part of its remaining territory. For example, during World War I, nearly all of Belgium was occupied by Germany, but Belgium and its allies held on to a small slice in the country's west. A government in exile, in contrast, has lost all its territory. However, in practice, the distinction may be unclear; in the above example, the Belgian government at Sainte-Adresse was located in French territory and acted as a government in exile for most practical purposes. Governments-in-exile and associated organisations employ strategies such as investigative reporting and diaspora mobilisation to sustain political visibility, engage supporters, and address ethical and operational challenges.

Governments in exile tend to occur during wartime occupation or in the aftermath of a civil war, revolution, or military coup. For example, during German expansion and advance in World War II, some European governments sought refuge in the United Kingdom, rather than face destruction at the hands of Nazi Germany. On the other hand, the Provisional Government of Free India proclaimed by Subhas Chandra Bose sought to use support from the invading Japanese to gain control of the country from what it viewed as British occupiers, and in the final year of WWII, after Nazi Germany was driven out of France, it maintained the remnants of the Nazi-sympathizing Vichy government as a French government in exile at the Sigmaringen enclave.

The Indian Legion (German: Indische Legion), officially the Free India Legion (German: Legion Freies Indien) or 950th (Indian) Infantry Regiment (German: Infanterie-Regiment 950 (indisches)), was a military unit raised during the Second World War initially as part of the German Army and later the Waffen-SS from August 1944. Intended to serve as a liberation force for British-ruled India, it was made up of Indian prisoners of war and expatriates in Europe. Owing to its origins in the Indian independence movement, it was known also as the "Tiger Legion", and the "Azad Hind Fauj". As part of the Waffen-SS it was known as the Indian Volunteer Legion of the Waffen-SS (German: Indische Freiwilligen Legion der Waffen-SS). The transfer to the Waffen-SS was never fully executed and many members of the division refused to wear the new uniforms and insignia.

Indian independence leader Subhas Chandra Bose initiated the legion's formation, as part of his efforts to win India's independence by waging war against Britain, when he came to Berlin in 1941 seeking German aid. The initial recruits in 1941 were volunteers from the Indian students resident in Germany at the time, and a handful of the Indian prisoners of war who had been captured during the North African campaign. It later drew a larger number of Indian prisoners of war as volunteers.

Sonderreferat Indien, variously translated into English as, Special Bureau for India, Special India Bureau, or Section for Indian Affairs, was a section or bureau established within the Information Department of the Foreign Office of Nazi Germany in late spring 1941 in response to a proposal or memorandum written by the Indian nationalist Subhas Chandra Bose, who had arrived in Germany in early April of that year. The main function of the bureau was to aid Bose in his work, to liaise with Bose, and to mobilize an Indian Legion, comprising Indian prisoners of war captured by Erwin Rommel's Afrika Korps, to aid the German military in a future land invasion of India. A military intervention in India, one of the two major points in Bose's proposal, had at first received a lukewarm response from the German Foreign Minister Joachim von Ribbentrop, but shortly afterwards it received the unexpected support of Adolf Hitler, who saw the battle for India as the natural aftermath of a successful German invasion of Russia and a chance to deliver the ultimate blow to the British Empire.

Wilhelm Keppler, then an under-secretary of State in the German Foreign Office, who had direct access to Ribbentrop, was appointed director of the bureau. Most of the day-to-day work, however, became the responsibility of Adam von Trott zu Solz, an anti-Nazi official, who had some knowledge of India. Immediately under von Trott was his longtime friend Alexander Werth, who earlier had been imprisoned by the Nazis for a few years, along with ten other remaining members of staff. Bose was required to be addressed as "His Excellency" by order of the senior officials in the Foreign Office.

The Indian National Army (INA, sometimes Second INA; Azad Hind Fauj /ˈɑːzɑːð ˈhinð ˈfɔːdʒ/; lit. 'Free Indian Army') was a Japanese-allied and -supported armed force constituted in Southeast Asia during World War II and led by Indian anti-colonial nationalist Subhas Chandra Bose. It consisted primarily of British Indian Army POWs taken by Japan. Indian civilians in the region were also enlisted, with around 18,000 joining. The INA aimed to liberate India from British rule. After winning Japanese assent for its goal, the INA furnished support to the Japanese Army. The Japanese and INA forces invaded India from Rangoon in 1944, and Bose's nominal Provisional Government of Azad Hind declared war on Britain. Losses inflicted by the British in the Battle of Imphal in Manipur caused the invasion to be halted. A long and exhausting withdrawal, accompanied by a lack of supplies, malnutrition, and death, ensued, some victorious soldiers in the Indian Army not taking INA battlefield surrender kindly. The remaining INA was driven down the Malay Peninsula and surrendered to Allied forces in August 1945.

An earlier incarnation of the INA, the First Indian National Army, had been founded in 1942 by Iwaichi Fujiwara and Mohan Singh. However, Mohan Singh refused to align with the Japanese, leading to his arrest and the First INA's disbandment. After Subhas Chandra Bose arrived in Southeast Asia from Nazi Germany in May 1943, he refounded the INA with significant recruitment from Indian civilian communities in Malaya and Singapore.
