The Indian National Army was organized to fight against

1. India's Political Climate during World War II (basic)

To understand the revolutionary movements of the 1940s, we must first look at the spark that set the stage: the outbreak of World War II in September 1939. The political climate in India turned volatile almost overnight when the Viceroy, Lord Linlithgow, declared India a belligerent in the war against Germany without consulting a single Indian leader or the provincial legislatures. This 'unilateral declaration' was seen as a grave insult to Indian self-respect. In response, the Indian National Congress, which had been governing several provinces since 1937, demanded that Britain clarify its war aims—specifically, whether they included the granting of independence to India. When the British gave a vague response, the Congress ministries resigned in protest in October 1939 Rajiv Ahir, A Brief History of Modern India, Congress Rule in Provinces, p.415.

2. The Quit India Movement (1942) (basic)

The Quit India Movement, also known as the August Kranti, was the final massive push for independence. It didn't emerge in a vacuum; it was born out of deep frustration following the failure of the Cripps Mission in early 1942. With World War II raging and the Japanese army reaching India's borders, Mahatma Gandhi felt that British presence was an invitation to Japanese invasion. He famously remarked that the British should leave India to "God" or even to "anarchy," arguing that the current "ordered anarchy" of colonial rule had to end History, class XII (Tamilnadu state board 2024 ed.), Last Phase of Indian National Movement, p.87.

The movement's roadmap was laid out in two key steps. First, in July 1942, the Congress Working Committee met at Wardha and passed a resolution authorizing Gandhi to lead a non-violent mass movement Rajiv Ahir. A Brief History of Modern India (2019 ed.), Chapter 23, p.448. This was later ratified on August 8, 1942, at the Gowalia Tank Maidan in Bombay. The resolution demanded an immediate end to British rule, the formation of a provisional Indian government, and expressed a commitment to defend India against Fascism and Imperialism once free Rajiv Ahir. A Brief History of Modern India (2019 ed.), Chapter 23, p.448.

At this historic Bombay session, Gandhi delivered his soul-stirring "Do or Die" speech. He told the nation, "We shall either free India or die in the attempt; we shall not live to see the perpetuation of our slavery." Unlike previous movements, this was envisioned as a "fight to the finish." Although the British arrested the entire top leadership of the Congress on the morning of August 9th, the movement survived through the initiative of common people and underground heroes like Usha Mehta, who operated a clandestine radio to keep the spirit of revolution alive History, class XII (Tamilnadu state board 2024 ed.), Last Phase of Indian National Movement, p.97.

3. The Failure of the Cripps Mission (intermediate)

In March 1942, as the clouds of World War II darkened over India with the Japanese army reaching the borders of Burma, the British government sent Sir Stafford Cripps to negotiate with Indian leaders. The mission's primary goal was to secure full Indian cooperation in the war effort in exchange for a promise of self-government later History, class XII (Tamilnadu state board 2024 ed.), Last Phase of Indian National Movement, p.86. Cripps, a member of the British War Cabinet with known sympathies for Indian aspirations, proposed a Dominion Status for India after the war, along with the creation of a Constituent Assembly to frame a new constitution. However, the mission was ultimately seen as "too little, too late."

The failure of the mission stemmed from fundamental disagreements between the British proposals and the demands of Indian political parties. The Indian National Congress (INC) was dissatisfied because the offer did not include immediate Purna Swaraj (complete independence) and insisted that the British retain control over India's defense during the war. Furthermore, the INC strongly objected to the "opt-out" clause, which allowed any province or princely state to refuse the new constitution and maintain a separate relationship with Britain—a provision they saw as a blueprint for the partition of India Introduction to the Constitution of India, D. D. Basu (26th ed.), OUTSTANDING FEATURES OF OUR CONSTITUTION, p.51.

Stakeholder	Primary Reason for Rejection
Indian National Congress	Objected to Dominion Status instead of full independence and the right of provinces to secede.
Muslim League	Felt the proposals did not explicitly recognize the demand for a separate state (Pakistan).
Hindu Mahasabha	Opposed the "opt-out" clause as it threatened national unity.

The most famous critique came from Mahatma Gandhi, who described the offer as "a post-dated cheque on a crashing bank." To understand this analogy, think of a post-dated cheque as a promise that cannot be cashed until a future date—in this case, after a war that Britain might not even win Indian Economy, Nitin Singhania (ed 2nd 2021-22), Money and Banking, p.194. This fundamental lack of trust, combined with Winston Churchill's reluctance to truly part with power, ensured the mission's collapse. This failure directly cleared the stage for the Quit India Movement later that year Rajiv Ahir. A Brief History of Modern India (2019 ed.), Chapter 23, p.442.

4. Parallel Governments: Internal Resistance (intermediate)

Hello! It is wonderful to have you here as we dive into one of the most defiant chapters of the Indian national movement. While the Quit India Movement (1942) is often remembered for Gandhi's "Do or Die" call, its true revolutionary spirit manifested in the complete breakdown of British authority in several pockets of India. In these areas, the British didn't just lose control—they were replaced. This is the phenomenon of Parallel Governments (or Prati Sarkars).

A parallel government is exactly what it sounds like: a shadow administration that takes over the functions of the state—such as policing, justice, and tax collection—while the formal government is still technically in power but effectively paralyzed. During 1942, as the top Congress leadership was whisked away to jail, local leaders and the masses took the initiative. This wasn't just chaos; it was an attempt to prove that Indians could govern themselves even under the shadow of war. This internal resistance was complemented by underground activities led by figures like Jayaprakash Narayan, Aruna Asaf Ali, and Ram Manohar Lohia, who operated secret radio stations and organized sabotage to disrupt the British war effort Rajiv Ahir, A Brief History of Modern India, After Nehru..., p.814.

To understand the depth of this resistance, let’s look at the three most prominent examples of these "rebel republics":

Location	Key Features & Leaders	Significance
Ballia (UP)	Led by Chittu Pandey (August 1942).	The first to emerge; it lasted only a week but succeeded in releasing many jailed Congress leaders Rajiv Ahir, A Brief History of Modern India, Chapter 23, p.450.
Tamluk (Bengal)	The Tamralipta Jatiya Sarkar (1942–44).	Highly organized. It formed Vidyut Vahinis (lightning corps), provided cyclone relief, and distributed paddy to the poor Rajiv Ahir, A Brief History of Modern India, Chapter 23, p.450.
Satara (Maharashtra)	Led by Nana Patil and Y.B. Chavan (1943–45).	The longest-lasting government. It set up Nyayadan Mandals (people's courts) and village libraries Rajiv Ahir, A Brief History of Modern India, Chapter 23, p.450.

These governments were a psychological blow to the British. They proved that the Raj relied on the acquiescence of the governed; once that was withdrawn, the mighty British administrative machinery could be replaced by a local panchayat or a Jatiya Sarkar in a matter of days.

5. Japan’s Advance and the Indian Independence League (intermediate)

As the Second World War engulfed the globe, the rapid advance of Imperial Japan through Southeast Asia created a unique strategic opening for Indian revolutionaries. By early 1942, the Japanese had captured key British strongholds like Singapore, Malaya, and Burma Modern India, Bipin Chandra, Struggle for Swaraj, p.298. This collapse of British power left thousands of Indian soldiers—who were part of the British Indian Army—as Prisoners of War (POWs). It was in this chaotic vacuum that the idea of an army of liberation took root. Initially, Captain Mohan Singh, a British Indian Army officer, decided to seek Japanese assistance to form a military wing composed of these POWs to fight for India's freedom Rajiv Ahir, A Brief History of Modern India, Chapter 23, p.458.

While the military arm was taking shape, the political groundwork was being laid by the veteran revolutionary Rashbehari Bose. Having lived in exile in Japan for decades, he organized the Indian Independence League (IIL) in Tokyo in 1942 to mobilize the Indian diaspora and coordinate with the Japanese government. At the Bangkok Conference in June 1942, it was formally decided that the Indian National Army (INA) would function under the leadership of the League Rajiv Ahir, A Brief History of Modern India, Chapter 23, p.459. However, the first phase of the INA faced internal friction between Mohan Singh and the Japanese command over the scale and autonomy of the force.

The movement found its ultimate catalyst when Subhas Chandra Bose arrived in Singapore in July 1943. In a remarkable transition of power, Rashbehari Bose handed over the leadership of the Indian Independence League and the INA to Subhas. This "spadework" by Rashbehari was essential; it provided the structure upon which Subhas Bose built the Provisional Government of Free India (Azad Hind) in October 1943 History, class XII (Tamilnadu state board 2024 ed.), Last Phase of Indian National Movement, p.89. This government, recognized by the Axis powers, declared war on Britain and set the stage for a military offensive on Indian soil.

6. Subhas Chandra Bose: From Congress to Azad Hind (intermediate)

To understand Subhas Chandra Bose, we must see him as the bridge between mainstream nationalist politics and revolutionary armed struggle. A man of exceptional intellect who secured the fourth rank in the Indian Civil Service, he resigned in 1921 because he refused to serve the British Crown, choosing instead the mentorship of Chittaranjan Das Rajiv Ahir, Modern India, Chapter 23, p.456. While Bose was twice elected President of the Congress, his fundamental belief that 'freedom is not given, it is taken' eventually led to an ideological rupture with Mahatma Gandhi's non-violent approach. This culminated in his departure from India in 1941 — a daring escape disguised as Ziauddin — to seek international support for India's liberation Rajiv Ahir, Modern India, Chapter 23, p.457. Bose's arrival in Southeast Asia revitalized a stagnating movement. Originally conceptualized by Mohan Singh and supported by the Japanese, the INA (Azad Hind Fauj) became a formidable force under 'Netaji.' He established the Provisional Government on October 21, 1943, which was recognized by the Axis powers Tamilnadu State Board, History Class XII, p.89. This wasn't just a militia; it was a sovereign government in exile with its own currency and civil code. The INA's military campaign reached Indian soil in 1944, famously hoisting the tricolor at Moirang, Manipur Rajiv Ahir, Modern India, Chapter 23, p.460. Though the campaign eventually stalled due to logistics and the retreat of the Japanese, it shattered the myth of the Indian soldier’s absolute loyalty to the British Crown, making the continuation of the Raj untenable.

7. The Aftermath: INA Trials and Naval Mutiny (exam-level)

As World War II drew to a close in 1945, the British government found itself in a precarious position. While they had emerged victorious globally, their authority in India was crumbling. The catalyst for this final breakdown was the INA Trials (also known as the Red Fort Trials). The British decided to publicly prosecute officers of the Indian National Army (INA)—specifically General Shah Nawaz Khan, Gurdial Singh Dhillon, and Prem Sehgal—for treason. This move backfired spectacularly. Because the three accused belonged to different religions (Muslim, Sikh, and Hindu), the trial became a symbol of communal unity and national defiance rather than a simple criminal proceeding Modern India, Bipin Chandra, Struggle for Swaraj, p.301.

The defense of these officers was taken up by the INA Defence Committee, which saw legal giants like Bhulabhai Desai, Tej Bahadur Sapru, and even Jawaharlal Nehru (wearing his lawyer's robes after decades) fighting the case. This legal battle spilled over into the streets, leading to what historians call the "Three Upsurges" of the winter of 1945-46. These were not just peaceful protests but violent confrontations that showed the British their days were numbered:

The Royal Indian Navy Mutiny was perhaps the most significant turning point. It wasn't just a local riot; it was a military revolt. Sailors took over ships, replaced British flags with the tricolor, and were supported by massive crowds in Bombay. This event sent a clear message to London: the Indian military, the very instrument the British used to hold India, could no longer be trusted to remain loyal to the Crown. The agitation had "penetrated the traditional bulwarks of the Raj"—the armed forces and government employees A Brief History of Modern India, Spectrum, Post-War National Scenario, p.489. By 1946, the struggle was no longer about whether the British would leave, but how soon they would go.

8. Evolution and Objectives of the Indian National Army (INA) (exam-level)

The evolution of the Indian National Army (INA), or the Azad Hind Fauj, represents a unique chapter where the Indian freedom struggle went global and military. The movement evolved in two distinct phases. The First Phase began around 1942 in the wake of the British retreat from South-East Asia during World War II. Captain Mohan Singh, an officer in the British Indian Army, decided to seek Japanese assistance rather than retreating. The Japanese, who had been encouraging anti-British sentiments among Indian civilians, handed over Indian Prisoners of War (POWs) to Singh. Following the fall of Singapore, his forces swelled to nearly 45,000 men Rajiv Ahir, A Brief History of Modern India (2019 ed.), Chapter 23, p.458. Initially, the INA's philosophy was cautious; it intended to act only upon a formal invitation from the Indian National Congress History, Class XII (Tamilnadu State Board 2024 ed.), p.89.
The Second Phase began with the arrival of Subhas Chandra Bose in Singapore in July 1943. Bose took over the leadership from the veteran revolutionary Rashbehari Bose and infused the movement with a new administrative and ideological vigor. On October 21, 1943, he established the Provisional Government of Free India (Arzi Hukumat-e-Azad Hind) in Singapore. This was not just a military unit but a 'state-in-exile' with its own cabinet, including Captain Lakshmi Swaminathan (heading the Women’s Department/Rani of Jhansi Regiment) and H.C. Chatterjee (Finance) Rajiv Ahir, A Brief History of Modern India (2019 ed.), Chapter 23, p.459. This government was formally recognized by the Axis powers, including Japan and Germany, effectively internationalizing India's demand for sovereignty.
The primary objectives of the INA were to launch a military offensive against the British Raj from the outside, synchronized with internal civilian revolts. Bose famously characterized this as 'India's last war of independence.' The INA's strategy involved a tactical alliance with Japan to gain a foothold on Indian soil. They successfully reached Kohima and Imphal, and in April 1944, the Indian Tricolor was hoisted at Moirang, Manipur Rajiv Ahir, A Brief History of Modern India (2019 ed.), Chapter 23, p.461.

9. Solving the Original PYQ (exam-level)

Connecting the building blocks you've just studied, the formation of the Indian National Army (INA), or Azad Hind Fauj, represents the shift from internal civil disobedience to an external military offensive during World War II. While the Quit India Movement challenged British authority from within, the INA, as detailed in A Brief History of Modern India by Rajiv Ahir, sought to liberate the motherland from the outside by leveraging the global geopolitical landscape. To solve this, you must distinguish between the INA's allies and its adversaries; while they collaborated with the Axis powers, their singular, unwavering objective was the termination of the British Raj.

When approaching this question, use the process of elimination by identifying the primary conflict of the era. Since the INA was composed of Indian prisoners of war captured by the Japanese, it is logical to conclude they would not fight their liberators (Japan) or their liberators' allies (Germany). Instead, they directed their military efforts toward the British in India, launching campaigns in the northeast to hoist the tricolor on Indian soil. Therefore, Option (B) is the only choice that aligns with the nationalist goal of Purna Swaraj (complete independence) through armed struggle.

UPSC often uses "geopolitical traps" like Options (A) and (C) to confuse students who know the INA was active in the Pacific Theater. Japan and Germany were actually strategic partners of Subhas Chandra Bose, providing the logistical support and manpower needed to organize the front. Option (D) Russia is a distractor, as the Soviet Union was part of the Allied forces but was not the primary colonial occupier the INA was designed to displace. Always keep the core objective—Indian Independence—as your north star when evaluating these historical movements.
