The Indian National Congress agreed in 1947 to the partition of the country mainly because

1. Evolution of the Two-Nation Theory and Pakistan Demand (basic)

The Two-Nation Theory is the ideological foundation that asserted that Hindus and Muslims were not just two different religious communities, but two distinct nations with separate cultures, histories, and political interests. This theory did not emerge suddenly; it was a gradual evolution from the late 19th century. Initially, the discourse focused on securing safeguards for Muslims as a minority, but by 1940, it transformed into a demand for sovereign statehood. History , class XII (Tamilnadu state board 2024 ed.), Last Phase of Indian National Movement, p.91

The early roots can be traced to 1887, when Sir Syed Ahmed Khan urged Muslims to stay away from the Congress, fearing that a representative government based on a simple majority would lead to the permanent domination of the Hindu majority over the Muslim minority. This sentiment was institutionalized in 1906 with the Shimla Deputation, where Muslim leaders demanded separate electorates—a system where Muslims would vote only for Muslim candidates—to ensure their "political importance" was recognized. Rajiv Ahir. A Brief History of Modern India, Post-War National Scenario, p.485

The decisive turning point was the Lahore Resolution of March 24, 1940 (often called the 'Pakistan Resolution'). Under the leadership of Mohammed Ali Jinnah, the Muslim League moved beyond asking for constitutional protections. They argued that Muslims were a nation by any definition and demanded the grouping of geographically contiguous Muslim-majority areas in the North-Western and Eastern zones into independent, autonomous, and sovereign states. Rajiv Ahir. A Brief History of Modern India, Post-War National Scenario, p.488. During World War II, the British government gave the League a "virtual veto" on any political settlement, which Jinnah used to ensure that no constitutional progress occurred without conceding the demand for Pakistan.

However, the theory was not universally accepted by all Muslims. For instance, Khan Abdul Ghaffar Khan (the 'Frontier Gandhi'), leader of the North Western Frontier Province, remained a staunch opponent of the Two-Nation Theory until the very end. Despite such internal opposition, the British and the League's persistence eventually made the partition of the subcontinent along religious lines an unavoidable reality.

2. Failed Mediations: From CR Formula to Cabinet Mission (intermediate)

Between 1944 and 1946, as the Second World War drew to a close, India witnessed a series of high-stakes political negotiations. These were not merely debates over seats; they were desperate attempts to find a middle ground between the Indian National Congress, which envisioned a united, secular India, and the Muslim League, which was increasingly firm on the demand for Pakistan. Understanding why these talks failed explains why partition eventually became the only path the British and Indian leaders could see.

The first major attempt was the CR Formula (1944), proposed by C. Rajagopalachari. He suggested a "tactical compromise": the League would support the demand for independence and join an interim government; in return, after the war, a plebiscite would be held in Muslim-majority districts to decide if they wanted to separate Rajiv Ahir, A Brief History of Modern India, Chapter 25, p.461. However, during the subsequent Gandhi-Jinnah talks, Jinnah rejected the offer. He insisted that the Congress first accept the Two-Nation Theory — the idea that Hindus and Muslims were two distinct nations — and he objected to non-Muslims in those districts having a vote in the plebiscite History, Tamilnadu state board 2024 ed., Chapter 8, p.92.

The deadlock moved from private talks to a formal summit at the Shimla Conference (1945) under the Wavell Plan. Lord Wavell proposed an Executive Council that would be entirely Indian, except for the Viceroy and the Commander-in-Chief, with "equal representation" for Caste Hindus and Muslims Rajiv Ahir, A Brief History of Modern India, Chapter 25, p.455. This mediation collapsed on a fundamental question of identity: Jinnah demanded that the Muslim League be the sole authority to nominate all Muslim members to the council. The Congress, represented by its president Maulana Abul Kalam Azad, refused to accept this, as it would mean abandoning its identity as a national party representing all Indians, including Muslims History, Tamilnadu state board 2024 ed., Chapter 8, p.92.

The final effort was the Cabinet Mission (1946). Unlike previous plans, it explicitly rejected the idea of a fully sovereign Pakistan, fearing it would be unviable. Instead, it proposed a three-tier structure where provinces would be grouped into three sections (A, B, and C) with a weak central government handling only defense, foreign affairs, and communications Rajiv Ahir, A Brief History of Modern India, Chapter 25, p.823. While both parties initially flirted with the idea, it ultimately failed because of disagreements over whether the "grouping" of provinces was compulsory or optional. This failure was the "point of no return," leading directly to the communal violence of Direct Action Day.

3. The Breakdown of Governance: Interim Government (1946-47) (intermediate)

To understand the eventual Partition of India, we must look at the Interim Government (1946-47), which was meant to be a bridge to independence but instead became a battlefield of political ideologies. Imagine a house where two roommates are forced to live together while arguing over how to divide the property—that was the state of the Indian administration during these months.

On September 2, 1946, an Interim Government headed by Jawaharlal Nehru was sworn in. Initially, the Muslim League stayed away, but Viceroy Lord Wavell later persuaded them to join on October 26, 1946, to ensure a representative character History, Class XII (Tamil Nadu state board 2024), Last Phase of Indian National Movement, p.94. However, the League’s entry was not based on a spirit of cooperation. They joined without rescinding the call for 'Direct Action' and without accepting the Cabinet Mission's long-term plan. Their strategy was obstructionist—to fight for Pakistan from within the government rather than outside it Rajiv Ahir, A Brief History of Modern India (2019 ed.), Post-War National Scenario, p.476.

The administrative machinery soon ground to a halt. There were no informal cabinet meetings to settle differences, and the two parties functioned as two separate blocs. The breaking point arrived in March 1947 with the 'Poor Man’s Budget' presented by the Finance Minister, Liaquat Ali Khan. By proposing heavy taxes on big business houses (largely supporters of the Congress), the League paralyzed the Congress-led departments and effectively used the treasury to stall government functioning History, Class XII (Tamil Nadu state board 2024), Last Phase of Indian National Movement, p.95. This administrative deadlock, combined with the horrifying communal violence in Punjab and Bengal, convinced many leaders that a united government was no longer sustainable.

4. Adjacent Challenge: The Integration of Princely States (exam-level)

When the British departed in 1947, they didn't just leave behind a partitioned India; they left a "patchwork quilt" of over 560 semi-autonomous Princely States. Under British rule, these states were tied to the Crown through Paramountcy—a system where the British handled their defense and foreign affairs while the rulers enjoyed internal autonomy. With the Indian Independence Act of 1947, this paramountcy lapsed, technically leaving these states legally independent. The challenge for the new Indian government was to prevent the "Balkanization" of the subcontinent—a scenario where hundreds of tiny independent kingdoms would exist within India's borders.

To address this, Sardar Vallabhbhai Patel (head of the States' Ministry) and his secretary V.P. Menon launched a diplomatic masterstroke known as the "Patel Scheme." They appealed to the rulers' patriotism, urging them to accede to the Indian Dominion in three specific areas: Defence, Communications, and External Affairs. These were powers the states had already surrendered to the British, so the transition felt less like a loss of sovereignty and more like a change of allegiance. By August 15, 1947, 136 states had already joined the Indian Union Rajiv Ahir, A Brief History of Modern India, Chapter 25, p.607.

The legal mechanism for this was the Instrument of Accession. It is vital to note that while the integration of British Provinces into the new federation was automatic, the accession of Princely States was voluntary and rested solely on the decision of the Ruler D. D. Basu, Introduction to the Constitution of India, OUTSTANDING FEATURES OF OUR CONSTITUTION, p.50. Once joined, the process evolved into a three-fold integration: merging small states into larger viable units, democratizing their internal administration, and eventually fitting them into the constitutional structure of India D. D. Basu, Introduction to the Constitution of India, OUTSTANDING FEATURES OF OUR CONSTITUTION, p.51.

Feature	British Provinces	Princely States
Accession	Automatic and compulsory	Voluntary (via Instrument of Accession)
Authority	Full federal authority applied	Limited to terms of the Accession document
Residuary Powers	Held by the Federation/Center	Remained with the State (initially)

While most states joined peacefully, others like Jammu and Kashmir presented unique challenges. Maharaja Hari Singh only signed the Instrument of Accession on October 26, 1947, after facing an invasion. This document was legally identical to those signed by other rulers, yet the specific political turmoil surrounding it led to the temporary provision of Article 370 in the Constitution, granting the state a special autonomous status History, Class XII (TN Board), Chapter 8, p.106.

5. Socio-Economic Aftermath: Partition and Migration (intermediate)

The partition of India in 1947 was not merely a political event; it was a socio-economic earthquake that reshaped the subcontinent. The Indian National Congress, which had long championed a united India, eventually accepted partition as a 'tragic necessity.' This decision was driven by the total collapse of law and order and the realization that the country was on the brink of a full-scale civil war. Leaders like Mahatma Gandhi conceded that the widespread communal violence in Punjab and Bengal had left the leadership without the strength to resist the division Rajiv Ahir, A Brief History of Modern India, Chapter 25, p. 499.

The physical drawing of the border was entrusted to the Boundary Commission, chaired by Sir Cyril Radcliffe. Working under an 'absurd hurry' of just six weeks and using outdated census data and maps, the commission had to navigate complex geographical and social terrains Rajiv Ahir, A Brief History of Modern India, Chapter 25, p. 593. While religious demography was the primary factor, Radcliffe also had to consider economic viability and infrastructure—such as ensuring that railway networks and canal systems (like those in Punjab) remained functional Majid Husain, Geography of India, India–Political Aspects, p. 35. Disputed areas, such as the Matabhanga River in Bengal or the Sylhet district, required delicate adjustments where river mid-lines or forest boundaries were used to finalize the international border Majid Husain, Geography of India, India–Political Aspects, p. 43.

Beyond the borders, the economic aftermath was devastating. Partition acted like the liquidation of a massive firm where Assets and Liabilities had to be split between the two new nations Macroeconomics (NCERT class XII 2025 ed.), Money and Banking, p. 39. This went beyond land and cash; it included the division of the civil service, the military, and even physical assets like office furniture and railway wagons. Crucially, the economic linkages were severed: the jute mills remained in West Bengal (India), while the raw-jute producing fields went to East Pakistan; similarly, cotton mills in Bombay and Ahmedabad were separated from the long-staple cotton-growing areas of West Punjab and Sindh. This led to a massive refugee crisis and a period of intense economic reconstruction for both nations.

Feature	Details of the Radcliffe Award
Primary Factor	Religious demography (Muslim vs. Non-Muslim majority areas).
Secondary Factors	Natural boundaries (rivers), administrative units, railways, and canal systems.
Constraints	Extreme time pressure (6 weeks) and outdated maps/census data.

6. The Mountbatten Plan and the 'Tragic Necessity' (exam-level)

By early 1947, the dream of a united India was colliding with a brutal reality. After the Muslim League’s 'Direct Action Day' on August 16, 1946, a wave of communal violence swept across Calcutta and North India, making it clear that the Cabinet Mission’s plan for a loose federation was no longer workable History, class XII (Tamilnadu state board 2024 ed.), Communalism in Nationalist Politics, p.80. When Lord Mountbatten arrived as Viceroy in March 1947, his primary task was to find a way out of the deadlock. He soon realized that the only alternative to a partition was a prolonged civil war. This realization led to the June Third Plan (or Mountbatten Plan), which proposed the partition of the country and the creation of two separate dominions: India and Pakistan.

The mechanics of the Plan were clinical. It decided that the Provincial Legislative Assemblies of Bengal and Punjab would meet in two parts—one representing Muslim-majority districts and the other the rest—to vote on whether the province should be partitioned Introduction to the Constitution of India, D. D. Basu (26th ed.), THE MAKING OF THE CONSTITUTION, p.18. To draw the actual borders, two Boundary Commissions were appointed under Sir Cyril Radcliffe Rajiv Ahir, A Brief History of Modern India (2019 ed.), After Nehru..., p.823. Most significantly, Mountbatten advanced the date of British withdrawal to August 15, 1947, leaving a mere 11 weeks to divide an entire subcontinent's assets, military, and civil services History, class XII (Tamilnadu state board 2024 ed.), Last Phase of Indian National Movement, p.95.

Why did the Congress, which had fought for decades for a united India, finally agree? It was framed as a 'Tragic Necessity'. Senior leaders like Nehru and Patel concluded that a partitioned India with a strong central government was better than a united India that was paralyzed and bleeding from constant riots. Mahatma Gandhi, though deeply pained, eventually conceded that since communal violence had become so widespread, the Congress no longer possessed the strength to resist the division without risking further slaughter Rajiv Ahir, A Brief History of Modern India (2019 ed.), Independence with Partition, p.499. The formal acceptance came on June 15, 1947, through a resolution moved by Govind Ballabh Pant at the All India Congress Committee (AICC) History, class XII (Tamilnadu state board 2024 ed.), Last Phase of Indian National Movement, p.95.

7. Solving the Original PYQ (exam-level)

Now that you have mastered the timeline from the Cabinet Mission Plan to the Mountbatten Plan, you can see how these individual building blocks click together. The core concept at play here is the transition of the Indian National Congress from a stance of uncompromising unity to one of tragic pragmatism. By 1947, the failure of the Interim Government to function effectively and the paralysis caused by the Congress-League deadlock meant that the administrative machinery had broken down. The lessons you learned regarding Direct Action Day and the subsequent violence in Noakhali and Punjab are the direct precursors to this decision.

To arrive at the correct answer, (C) they wanted to avoid large-scale communal riots, you must think like a strategist facing a "lesser of two evils" scenario. As highlighted in A Brief History of Modern India (Spectrum), leaders like Sardar Patel argued that partition was better than having the whole of India "go the way of Pakistan" through a total collapse of law and order. The reasoning was that a surgical amputation was preferable to the gangrene of a continuous civil war. The choice was not made out of a desire for division, but out of a desperate need to secure a stable, peaceful space for the remaining parts of the country to develop.

UPSC frequently uses distractor traps to test your conceptual clarity. Option (A) is a classic trap: while Congress accepted the physical partition, they never accepted the Two-Nation Theory as an ideology; they maintained that India was a secular nation. Option (B) suggests a helplessness that historically ignores the agency of the Congress leaders who actively chose this path to save the state from anarchy. Finally, option (D) is factually weak because the Attlee Declaration had already made Indian independence a certainty by June 1948. Therefore, the decision was specifically about the terms of that freedom, specifically the urgent need to stem the communal bloodshed that threatened to consume the entire subcontinent.
