Which party was founded by Subhash Chandra Bose in the year 1939 after he broke away from the Congress?

1. Rise of Left-Wing Trends within the Congress (basic)

Welcome to your first step in understanding the diverse ideological landscape of the Indian National Movement! To understand the Rise of Left-Wing Trends, we must first look at the global and internal shifts of the 1920s. After the sudden withdrawal of the Non-Cooperation Movement in 1922, many young nationalists felt a sense of disillusionment. At the same time, the success of the Russian Revolution (1917) began to ripple across the world, inspiring Indian leaders to look beyond political freedom and consider economic equality for the masses. NCERT Class IX History, Socialism in Europe and the Russian Revolution, p.46

This "Left Wing" within the Congress wasn't a separate party initially, but a radical ideological current led by Jawaharlal Nehru and Subhash Chandra Bose. These young leaders were critical of both the 'Swarajists' (who wanted to enter legislatures) and the 'No-Changers' (who focused only on Gandhian constructive work). They argued that the Congress needed to adopt a more consistent anti-imperialist stance and integrate the grievances of peasants and workers into the national struggle. Spectrum (Rajiv Ahir), Emergence of Swarajists, Socialist Ideas, Revolutionary Activities and Other New Forces, p.346

Their influence significantly shifted the Congress's goal. While the older leadership was initially content with Dominion Status (self-rule under the British Crown), the left-leaning youth pushed for Purna Swaraj (Complete Independence). In 1928, Bose and Nehru even formed the Independence for India League to pressure the Congress into adopting this radical goal, which finally happened at the historic Lahore Session in 1929. Spectrum (Rajiv Ahir), Nationalist Response in the Wake of World War II, p.417

2. The Haripura Session (1938) and Bose's Presidency (basic)

In 1938, the Indian National Congress met for its annual session at Haripura (Gujarat). This session is historically significant because it marked the rise of Subhas Chandra Bose as a national leader of the highest order, as he was elected President of the Congress unopposed. Bose brought a modern, radical, and leftist perspective to the nationalist movement, which stood in sharp contrast to the more traditional, agrarian-focused views of the older leadership. Rajiv Ahir. A Brief History of Modern India, Nationalist Response in the Wake of World War II, p.417

Bose’s presidency was defined by his scientific and industrial vision for India's future. Unlike Mahatma Gandhi, who championed decentralized village-based economies and cottage industries, Bose was a staunch advocate for large-scale industrialization. He believed that for India to overcome poverty and social backwardness, it must adopt modern science and technology. In his Haripura presidential address, he argued for a comprehensive scheme of industrial development under state-ownership and state-control, heavily inspired by the economic successes he observed in the Soviet Union. Rajiv Ahir. A Brief History of Modern India, Nationalist Response in the Wake of World War II, p.428

A landmark achievement of this session was the proposal to set up a National Planning Committee. Bose understood that independence was not just a political goal but an economic one; he wanted a blueprint for a post-colonial Indian economy. He reached out to Jawaharlal Nehru to chair this committee, effectively bringing together the two most prominent socialist-leaning leaders of the Congress. This committee laid the early groundwork for the planning model that India would eventually adopt after 1947. Rajiv Ahir. A Brief History of Modern India, Nationalist Response in the Wake of World War II, p.428

Beyond industry, Bose also used the Haripura platform to advocate for social reforms, such as the abolition of landlordism and the liquidation of agricultural debt. He viewed the national struggle as a multifaceted movement that needed to involve the youth, trade unions, and peasants. Rajiv Ahir.

3. The Tripuri Crisis (1939) and the Great Resignation (intermediate)

By 1939, a profound ideological rift had emerged within the Indian National Congress (INC). On one side was the 'Old Guard' led by Mahatma Gandhi, who favored a cautious, non-confrontational approach toward the British. On the other was Subhas Chandra Bose, who believed that the brewing international crisis (World War II) was a 'God-sent opportunity' to demand immediate independence. This tension reached its boiling point at the Tripuri Session in March 1939, located in present-day Madhya Pradesh Rajiv Ahir, A Brief History of Modern India, Nationalist Response in the Wake of World War II, p.418. Unlike previous years where the President was chosen by consensus, Bose decided to contest the election for a second term, representing the radical and socialist elements of the party.

The election became a symbolic battle for the Congress's future direction. Gandhi put his weight behind Pattabhi Sitaramayya, but Bose won by a margin of 1,580 votes to 1,377, thanks to the support of the Congress Socialist Party and Communists. Gandhi famously declared that 'Pattabhi’s defeat is my defeat', turning a democratic election into a personal crisis of leadership Rajiv Ahir, A Brief History of Modern India, Nationalist Response in the Wake of World War II, p.418. This led to a complete deadlock: most members of the Congress Working Committee resigned, and the Pant Resolution was passed, which mandated that Bose must appoint the new committee according to Gandhi's wishes. Bose felt he could not function as a 'puppet' president and chose to resign in April 1939.

Following his resignation, Bose did not immediately leave the Congress but instead formed the Forward Bloc in May 1939 as a radical faction within the party to unify left-wing elements. However, after he organized protests against certain Congress resolutions, the leadership took disciplinary action, removing him from his position as President of the Bengal Provincial Congress Committee and barring him from holding any elective office in the party for three years History, class XII (Tamilnadu state board 2024 ed.), Last Phase of Indian National Movement, p.85. This 'Great Resignation' and subsequent expulsion marked a definitive split, leading Bose to eventually seek international allies for India's liberation.

4. Parallel Movements: The Congress Socialist Party (CSP) (intermediate)

The Congress Socialist Party (CSP) represents a fascinating chapter in India's struggle for independence, where a radical ideological group chose to work within the umbrella of the Indian National Congress rather than opposing it from the outside. Formed in 1934, the CSP was born out of a sense of disillusionment among young leaders who felt the Congress leadership was becoming too conservative and constitutionalist following the suspension of the Civil Disobedience Movement Politics in India since Independence, NCERT 2025 ed., Era of One-party Dominance, p.34. These leaders, including Jayaprakash Narayan (JP), Acharya Narendra Dev, and Rammanohar Lohia, sought to push the Congress toward a more radical, egalitarian, and pro-peasant program, ensuring that 'Swaraj' meant more than just the exit of the British—it meant social and economic justice for the masses.

What made the CSP unique was its structural existence as a 'party within a party.' While it had its own constitution, membership, and distinct Marxist-Socialist ideology, its members remained primary members of the Indian National Congress Spectrum 2019 ed., Developments under Nehru’s Leadership, p.639. This dual identity allowed them to influence Congress policy from the inside, advocating for the abolition of Zamindari and the socialization of key industries. However, this relationship was often tense, as the 'Right Wing' of the Congress (led by figures like Sardar Patel) frequently clashed with the 'Left Wing' (the CSP and supporters of Nehru and Bose) over the pace and methods of the national movement.

The CSP's internal status ended shortly after independence. In 1948, the Congress leadership, seeking to consolidate power and ensure party discipline, amended the Congress constitution to prohibit dual party membership Politics in India since Independence, NCERT 2025 ed., Era of One-party Dominance, p.34. This forced the Socialists to make a choice, leading them to leave and form the independent Socialist Party. Although the party faced electoral struggles in post-independence India, its leaders remained pivotal figures in the opposition, with JP later leading the movement for 'Partyless Democracy' and Lohia advocating for 'militant mass movements' against the Congress hegemony Spectrum 2019 ed., Developments under Nehru’s Leadership, p.640.

Feature	Congress Socialist Party (CSP)	Communist Party of India (CPI)
Relation to Congress	Organized within the Congress (until 1948)	Independent organization; often at odds with Congress
Primary Goal	National independence + Socialist transformation	Proletarian revolution; internationalist outlook
Key Leadership	JP Narayan, Narendra Dev, Lohia	P.C. Joshi, S.A. Dange

5. The Indian National Army (Azad Hind Fauj) (intermediate)

The Indian National Army (INA), or the Azad Hind Fauj, represents one of the most romanticized and powerful chapters of the Indian freedom struggle. To understand the INA, we must look beyond the borders of India to Southeast Asia during the Second World War. The organization wasn't just a military unit; it was a political statement that Indians were willing to take up arms to secure Poorna Swaraj (Complete Independence).

The story of the INA unfolded in two distinct phases. The First Phase began around 1942, not with Subhas Chandra Bose, but with Captain Mohan Singh. As the British suffered defeats at the hands of the Japanese in Malaya and Singapore, thousands of Indian soldiers serving in the British Army became Prisoners of War (POWs). Mohan Singh, persuaded by Japanese military officer Major Fujiwara, realized these soldiers could be reorganized into a liberating force for India. By late 1942, nearly 40,000 men were ready to join Rajiv Ahir. A Brief History of Modern India (2019 ed.). SPECTRUM. Chapter 39: After Nehru... p. 458. However, disagreements between Mohan Singh and the Japanese command regarding the autonomy of the INA led to his arrest, and the first phase entered a period of uncertainty.

The Second Phase saw the arrival of the legendary Subhas Chandra Bose. Before this, Rashbehari Bose, a veteran revolutionary living in Japan since 1915, had established the Indian Independence League (IIL) to mobilize the Indian diaspora in East Asia History, class XII (Tamilnadu state board 2024 ed.). Chapter 7: Last Phase of Indian National Movement. p. 98. Recognizing the need for a dynamic leader, Rashbehari Bose invited Subhas Bose to take command. In July 1943, in Singapore, the leadership of the IIL and the INA was formally handed over to Subhas Chandra Bose, who breathed new life into the movement with his famous slogan, "Chalo Delhi".

Under Netaji (as Subhas Bose came to be known), the INA became a truly nationalistic force, famously including the Rani of Jhansi Regiment, one of the first all-female combat units in modern history. The INA's significance lies in its psychological impact: it shattered the British belief in the absolute loyalty of the Indian soldier, which had been the backbone of colonial rule for nearly two centuries Rajiv Ahir.

6. Formation and Ideology of the Forward Bloc (exam-level)

The formation of the Forward Bloc marks a definitive shift in the Indian national movement, representing the climax of the ideological rift between the 'Left' and 'Right' wings of the Indian National Congress (INC). Following the Tripuri Session (1939), where Subhas Chandra Bose was re-elected as President but faced intense opposition from the Gandhian old guard, Bose found it impossible to function. He resigned from the Congress Presidency in April 1939 Rajiv Ahir, A Brief History of Modern India, Nationalist Response in the Wake of World War II, p.420. On May 3, 1939, he announced the formation of the Forward Bloc at Makur, Unnao. Crucially, the Forward Bloc was initially intended to be a faction within the Congress, aimed at consolidating all radical, socialist, and left-leaning elements to push for a more militant nationalist policy.

The ideology of the Forward Bloc was centered on uncompromising anti-imperialism and the immediate launch of a mass struggle. While Mahatma Gandhi believed the country was not yet ready for a non-violent movement and did not wish to take advantage of Britain’s peril during World War II, Bose viewed the war as a historic opportunity to strike Rajiv Ahir, A Brief History of Modern India, Nationalist Response in the Wake of World War II, p.419. The Bloc sought to move beyond the 'wait and watch' policy of the Congress leadership, advocating for a total mobilization of the masses, including peasants and workers, to achieve Purna Swaraj (Complete Independence).

In March 1940, the Forward Bloc demonstrated its organizational strength by convening the Anti-Compromise Conference at Ramgarh, Bihar, held simultaneously with the official Congress session. This conference, a joint effort with the All India Kisan Sabha, resolved that a worldwide struggle should be launched, signaling Bose’s total break from the path of constitutional negotiations Rajiv Ahir, A Brief History of Modern India, Quit India Movement, Demand for Pakistan, and the INA, p.456. Shortly after, Bose’s radical activities led to his arrest and subsequent removal from all Congress positions, eventually paving the way for his daring escape from India in 1941 to seek external help for India's liberation.

7. Solving the Original PYQ (exam-level)

This question directly tests your understanding of the Tripuri Crisis and the ideological friction between the Left and Right wings of the Indian National Congress. After being elected President in 1939 but facing a lack of cooperation from the Congress Working Committee (the Old Guard), Subhash Chandra Bose realized he needed a new platform to pursue his radical, anti-compromise agenda against British rule. The building blocks you learned regarding his resignation and the subsequent need for a militant, left-wing faction within the Congress lead directly to this moment of political transformation.

To arrive at the correct answer, you must focus on the chronological anchor: the year 1939. While Bose is synonymous with the Azad Hind Fauj, your timeline should place that organization in the early 1940s during his activities in Southeast Asia. Immediately after resigning from the Congress presidency in India, he sought to unify all left-wing elements under a single banner to prepare for an immediate mass struggle. This faction was the (D) Forward Bloc. As detailed in A Brief History of Modern India (Spectrum), this was intended to be a vanguard to strengthen the Congress's revolutionary potential rather than a completely separate entity at its inception.

UPSC often uses "familiarity traps" to distract you. Option (B) Azad Hind Fauj is the most common trap; it is factually associated with Bose but is chronologically incorrect for the 1939 break-away period. Options (A) and (C) are generic distractors designed to sound plausible but they carry no specific historical weight in the context of Bose’s formal party foundations. Always prioritize the sequence of events: first, the ideological split in 1939 leading to the Forward Bloc, and later, the external military struggle with the Indian National Army.
