Making of the Indian Constitution: Notes, Key Dates and PYQs
How India's Constituent Assembly was formed and wrote the Constitution: key dates, committees, the Drafting Committee and borrowed features, with past exam questions.
By GK24 Editorial Team· Published · 8 min read

Almost every Polity paper in SSC, Railway and State exams has a question from this chapter. Who presided over the first sitting of the Constituent Assembly? When was the Constitution adopted, and why did it come into force only two months later? Which country gave us the Directive Principles? Learn this one chapter properly and you have marks that come back in paper after paper.
Where the idea came from
The demand that Indians should frame their own constitution grew out of the freedom movement. M.N. Roy was the first to put forward the idea of a Constituent Assembly, in 1934. The Indian National Congress made it an official demand in 1935, and the British government accepted the demand in principle in the August Offer of 1940. The Assembly was finally set up in 1946 under the Cabinet Mission Plan.
How the Assembly was formed
The Cabinet Mission Plan fixed the total strength of the Assembly at 389: 296 seats for British India and 93 for the princely states. Of the 296, 292 were for the eleven governors' provinces and 4 for the chief commissioners' provinces. Seats were shared out among the provinces broadly in proportion to their population.
The members were not elected directly by the people. The members of the provincial legislative assemblies elected them, using proportional representation by means of the single transferable vote. The representatives of the princely states were to be nominated by their rulers.
Elections to the 296 seats of British India were held in July and August 1946. The Congress won 208 seats, the Muslim League 73, and small groups and independents the remaining 15. After Partition, the members from the areas that went to Pakistan left the Assembly, and its strength came down to 299: 229 from the provinces and 70 from the princely states.
| Stage | British India (provinces) | Princely states | Total |
|---|---|---|---|
| Under the Cabinet Mission Plan, 1946 | 296 | 93 | 389 |
| After Partition, 1947 | 229 | 70 | 299 |
Remember: 389 at the start (296 + 93), 299 after Partition (229 + 70). The Assembly was indirectly elected and partly nominated, never directly elected by the people.
The Assembly at work: dates you must know
The Assembly met for the first time on 9 December 1946. The Muslim League stayed away and demanded a separate state of Pakistan. Dr Sachchidananda Sinha, the oldest member, was made the temporary President, following the French practice. Two days later, on 11 December 1946, Dr Rajendra Prasad was elected President of the Assembly, with H.C. Mukherjee and V.T. Krishnamachari as Vice-Presidents. Sir B.N. Rau was appointed its constitutional adviser.
| Date | What happened |
|---|---|
| 9 December 1946 | First meeting; Dr Sachchidananda Sinha temporary President |
| 11 December 1946 | Dr Rajendra Prasad elected President of the Assembly |
| 13 December 1946 | Jawaharlal Nehru moved the Objectives Resolution |
| 22 January 1947 | Objectives Resolution adopted |
| 22 July 1947 | National Flag adopted |
| 29 August 1947 | Drafting Committee set up under Dr B.R. Ambedkar |
| February 1948 | Draft Constitution published |
| 26 November 1949 | Constitution adopted (observed as Constitution Day) |
| 24 January 1950 | Last session; National Anthem and National Song adopted; Dr Rajendra Prasad elected first President of India |
| 26 January 1950 | Constitution came into force (Republic Day) |
The Objectives Resolution laid down the philosophy of the Constitution: India as an independent, sovereign republic, with justice, equality and freedom for all its people and safeguards for minorities and backward classes. Its ideas were later shaped into the Preamble.
The Assembly also had a second job. After independence it worked as the country's first Parliament, the Dominion Legislature. When it met as a legislature it was chaired by G.V. Mavalankar; when it met to frame the Constitution, Dr Rajendra Prasad presided.
Exam trap: 26 November 1949 is the day the Constitution was adopted; 26 January 1950 is the day it came into force. A few provisions, such as those on citizenship, elections, the provisional Parliament and temporary and transitional matters, took effect on 26 November 1949 itself. 26 January was chosen for the rest because the Congress had celebrated that day as Purna Swaraj Day in 1930.
The committees and their chairmen
The Assembly divided its work among a number of committees. Questions often give a committee and ask for its chairman, so learn them as pairs.
| Committee | Chairman |
|---|---|
| Union Powers Committee | Jawaharlal Nehru |
| Union Constitution Committee | Jawaharlal Nehru |
| States Committee (for negotiating with the princely states) | Jawaharlal Nehru |
| Provincial Constitution Committee | Sardar Vallabhbhai Patel |
| Advisory Committee on Fundamental Rights, Minorities and Tribal and Excluded Areas | Sardar Vallabhbhai Patel |
| Rules of Procedure Committee | Dr Rajendra Prasad |
| Steering Committee | Dr Rajendra Prasad |
| Ad hoc Committee on the National Flag | Dr Rajendra Prasad |
| Drafting Committee | Dr B.R. Ambedkar |
Two sub-committees of the Advisory Committee are also asked about: the Fundamental Rights Sub-Committee, chaired by J.B. Kripalani, and the Minorities Sub-Committee, chaired by H.C. Mukherjee.
Memory hook: Nehru took the Union and the States; Patel took the Provinces and the Rights; Prasad took the Rules, the Steering and the Flag; Ambedkar took the Draft.
The Drafting Committee
The most important of these, the Drafting Committee, was set up on 29 August 1947. It had seven members:
- Dr B.R. Ambedkar (Chairman)
- N. Gopalaswamy Ayyangar
- Alladi Krishnaswamy Ayyar
- Dr K.M. Munshi
- Syed Mohammad Saadullah
- N. Madhava Rau, who replaced B.L. Mitter when he resigned on grounds of health
- T.T. Krishnamachari, who replaced D.P. Khaitan after his death in 1948
The committee worked on the initial draft prepared by B.N. Rau and published its Draft Constitution in February 1948. The Assembly then went through the draft clause by clause, and more than two thousand proposed amendments were discussed on its floor. Ambedkar piloted the draft through the House, which is why he is remembered as the chief architect of the Constitution.
Time, sessions and the original document
The Assembly took 2 years, 11 months and 18 days to finish its work. In that time it held 11 sessions over 165 days, of which 114 days went into considering the draft. The total cost came to about ₹64 lakh.
As adopted in 1949, the Constitution had a Preamble, 395 Articles in 22 Parts and 8 Schedules. It has grown a great deal since then through amendments, so when a question says "originally", it means these numbers.
The original copies were written by hand, not printed. Prem Behari Narain Raizada wrote the English text in flowing italic calligraphy and Vasant Krishan Vaidya wrote the Hindi version, while artists of Shantiniketan led by Nandalal Bose decorated the pages. The elephant was the symbol (seal) of the Constituent Assembly.
Borrowed features: the sources of the Constitution
The framers studied the constitutions of many countries and adopted what suited Indian conditions, changing it where needed. The largest single source was the Government of India Act, 1935, and much of the structure of the Constitution comes from it.
| Source | Features taken |
|---|---|
| Government of India Act, 1935 | Federal scheme, office of Governor, judiciary, Public Service Commissions, emergency provisions and administrative details |
| Britain | Parliamentary government, rule of law, legislative procedure, single citizenship, cabinet system, prerogative writs, parliamentary privileges and bicameralism |
| United States | Fundamental Rights, independence of the judiciary, judicial review, impeachment of the President, removal of Supreme Court and High Court judges, and the post of Vice-President |
| Ireland | Directive Principles of State Policy, nomination of members to the Rajya Sabha and the method of election of the President |
| Canada | Federation with a strong Centre, residuary powers with the Centre, appointment of state Governors by the Centre and the advisory jurisdiction of the Supreme Court |
| Australia | Concurrent List, freedom of trade, commerce and intercourse, and the joint sitting of the two Houses of Parliament |
| Weimar Constitution of Germany | Suspension of Fundamental Rights during an Emergency |
| Former USSR | Fundamental Duties and the ideal of justice (social, economic and political) in the Preamble |
| France | Republic, and the ideals of liberty, equality and fraternity in the Preamble |
| South Africa | Procedure for amendment of the Constitution and election of members of the Rajya Sabha |
| Japan | Procedure established by law |
Memory hooks: Rights from the USA (its Bill of Rights), Directive Principles from Ireland, Duties from the USSR, the Concurrent List from Australia, emergency suspension of rights from Germany, and the amendment procedure from South Africa.

Practice MCQs on this topic
The constituent assembly was formed on the recommendation of the Cabinet Mission which visited India in______.
- A.1962
- B.1959
- C.1952
- D.1946
Show answer
Correct answer: D. 1946
Explanation
The correct answer is 1946. The Cabinet Mission came to India in 1946 to work out how power would be handed over, and its plan laid down how a Constituent Assembly would be formed: 389 seats in all, 296 for British India and 93 for the princely states, with the members from the provinces elected indirectly by the provincial legislative assemblies. Elections to the British Indian seats followed in July and August 1946, and the Assembly held its first meeting on 9 December 1946.
The other years cannot be right. The Constitution was adopted on 26 November 1949 and came into force on 26 January 1950, so an Assembly formed in 1952, 1959 or 1962 would have had nothing left to write. A good way to fix this date is to tie it to two others from the same year: the elections of July and August 1946, and the first sitting in December 1946.
When did the first meeting of the Constituent Assembly take place?
- A.January 1950
- B.August 1945
- C.December 1946
- D.July 1948
Show answer
Correct answer: C. December 1946
Explanation
The correct answer is December 1946. The Constituent Assembly met for the first time on 9 December 1946. The Muslim League boycotted the sitting and pressed its demand for a separate Pakistan, and Dr Sachchidananda Sinha, the oldest member, presided as temporary President. Two days later, on 11 December 1946, Dr Rajendra Prasad was elected the permanent President of the Assembly.
The other options are dates from before or after the Assembly's work. August 1945 is more than a year before the Cabinet Mission Plan of 1946 created the Assembly. July 1948 falls in the middle of its work, after the Draft Constitution had been published in February 1948. January 1950 is the very end: the last session was held on 24 January 1950 and the Constitution came into force on 26 January 1950. Remember the pair that is asked most often: first meeting on 9 December 1946, and Rajendra Prasad elected on 11 December 1946.
Who presided over the first meeting of the Constituent Assembly as its temporary President?
- A.Dr Rajendra Prasad
- B.Dr Sachchidananda Sinha
- C.Jawaharlal Nehru
- D.G.V. Mavalankar
Show answer
Correct answer: B. Dr Sachchidananda Sinha
Explanation
The correct answer is Dr Sachchidananda Sinha. When the Constituent Assembly met for the first time on 9 December 1946, Sinha, its oldest member, was made the temporary President, following the French practice of letting the senior-most member preside until a regular head is chosen.
Dr Rajendra Prasad is the classic trap: he was elected the permanent President of the Assembly on 11 December 1946, two days after the first sitting, so he did not preside over the first meeting. Jawaharlal Nehru's best-known role in the Assembly was moving the Objectives Resolution on 13 December 1946 and chairing committees such as the Union Powers Committee. G.V. Mavalankar presided when the Assembly sat as the Dominion Legislature, the country's first Parliament, not when it met to frame the Constitution. Keep the three offices apart: temporary President Sinha, President Prasad, and Mavalankar for the legislative sittings.
Who replaced Sachchidananda Sinha as Chairman of the Constituent Assembly of India?
- A.Pt. Jawaharlal Nehru
- B.Dr. Rajendra Prasad
- C.Sardar Vallabhbhai Patel
- D.Mohandas Karamchand Gandhi
Show answer
Correct answer: B. Dr. Rajendra Prasad
Explanation
The correct answer is Dr Rajendra Prasad. Dr Sachchidananda Sinha presided over the first sitting of the Constituent Assembly on 9 December 1946 only as its temporary President. On 11 December 1946 the Assembly elected Dr Rajendra Prasad as its permanent President, and he held that office until the Assembly finished its work. On 24 January 1950, at its last session, the Assembly also elected him the first President of India.
The other names played different parts. Jawaharlal Nehru moved the Objectives Resolution and chaired the Union Powers, Union Constitution and States Committees. Sardar Vallabhbhai Patel chaired the Provincial Constitution Committee and the Advisory Committee on Fundamental Rights and Minorities. Mahatma Gandhi was not a member of the Constituent Assembly at all. Exams like to pair the words "temporary" and "permanent", so fix the sequence: Sinha first, then Prasad two days later.
Who moved the Objective Resolution that was later adapted as the Preamble of the Constitution of India?
- A.Rajendra Prasad
- B.JB Kripalani
- C.Jawaharlal Nehru
- D.BR Ambedkar
Show answer
Correct answer: C. Jawaharlal Nehru
Explanation
The correct answer is Jawaharlal Nehru. Nehru moved the Objectives Resolution in the Constituent Assembly on 13 December 1946, and the Assembly adopted it on 22 January 1947. The resolution set out what the Constitution was meant to achieve: an independent, sovereign republic in which all people would have justice, equality and freedom, with safeguards for minorities and backward classes. Those ideas were later shaped into the Preamble.
Dr Rajendra Prasad was the President of the Assembly and presided over its debates; he did not move this resolution. J.B. Kripalani chaired the Fundamental Rights Sub-Committee. Dr B.R. Ambedkar chaired the Drafting Committee, which was set up only on 29 August 1947, months after the resolution had been adopted. A tidy way to remember the order: Nehru stated the objectives first, and Ambedkar's committee turned them into a draft later.
Who was the chairman of the drafting committee of the Constitution of India?
- A.B.R. Ambedkar
- B.K.M. Munshi
- C.Sardar Vallabhbhai Patel
- D.Mohammad Saadullah
Show answer
Correct answer: A. B.R. Ambedkar
Explanation
The correct answer is B.R. Ambedkar. The Drafting Committee was set up on 29 August 1947 with seven members, and Dr B.R. Ambedkar was its chairman. The committee published the Draft Constitution in February 1948, and Ambedkar piloted it through the Assembly's clause-by-clause debate, which is why he is remembered as the chief architect of the Constitution.
K.M. Munshi and Mohammad Saadullah were members of the same committee, not its chairman, which makes them the most tempting wrong answers. Sardar Vallabhbhai Patel was not on the Drafting Committee; he chaired the Provincial Constitution Committee and the Advisory Committee on Fundamental Rights, Minorities and Tribal and Excluded Areas. Learn the full list of seven members too, because a common variant asks which name was not a member: Ambedkar, N. Gopalaswamy Ayyangar, Alladi Krishnaswamy Ayyar, K.M. Munshi, Syed Mohammad Saadullah, N. Madhava Rau and T.T. Krishnamachari.
Who among the following personalities was appointed as the legal advisor of the Constituent Assembly that drafted the document of the Constitution?
- A.HVR Iyengar
- B.S.N. Mukherjee
- C.B.R. Ambedkar
- D.BN Rau
Show answer
Correct answer: D. BN Rau
Explanation
The correct answer is B.N. Rau. Sir Benegal Narsing Rau was appointed the constitutional (legal) adviser to the Constituent Assembly. He studied the constitutions of other countries and prepared the initial draft of the Constitution, which the Drafting Committee then worked on before publishing its own draft in February 1948.
B.R. Ambedkar is the most likely wrong pick: he chaired the Drafting Committee and steered the Constitution through the Assembly, but he was not the Assembly's adviser. H.V.R. Iyengar served as the Secretary of the Constituent Assembly, an administrative office, and S.N. Mukherjee was its chief draftsman. The distinction the question tests is between the adviser who prepared the first draft (Rau) and the committee chairman who guided the final text (Ambedkar). Questions sometimes use the words "legal adviser" and sometimes "constitutional adviser"; both point to B.N. Rau.
When did the Indian Constituent assembly adopt the constitution?
- A.26 November 1949
- B.26 January 1950
- C.26 November 1950
- D.26 January 1949
Show answer
Correct answer: A. 26 November 1949
Explanation
The correct answer is 26 November 1949. On that day the Constituent Assembly adopted the Constitution, and the date is now observed every year as Constitution Day. Some provisions, such as those on citizenship, elections, the provisional Parliament and temporary and transitional matters, took effect on 26 November 1949 itself.
26 January 1950 is the trap in this question: it is the date the Constitution came into force, now celebrated as Republic Day, not the date it was adopted. The day was chosen because the Congress had observed 26 January as Purna Swaraj Day in 1930. The other two options, 26 November 1950 and 26 January 1949, simply swap the years and match no event in the making of the Constitution. When you revise, keep the pair together in the right order: adopted on 26 November 1949, in force from 26 January 1950.
How long did the Constituent Assembly take to complete the Constitution of India?
- A.2 years, 11 months and 18 days
- B.3 years, 2 months and 10 days
- C.2 years, 6 months and 20 days
- D.1 year, 11 months and 18 days
Show answer
Correct answer: A. 2 years, 11 months and 18 days
Explanation
The correct answer is 2 years, 11 months and 18 days. The Assembly first met on 9 December 1946 and completed its work when the Constitution was adopted on 26 November 1949. In that time it held 11 sessions spread over 165 days, of which 114 days were spent considering the Draft Constitution. The total cost came to about ₹64 lakh.
The other options are built to look close. 1 year, 11 months and 18 days copies the months and days but drops a whole year. 3 years, 2 months and 10 days would carry the work past January 1950, when the Constitution had already come into force. 2 years, 6 months and 20 days is simply too short. A quick check that works in the exam hall: from December 1946 to late November 1949 is just under three years, which leaves only the first option standing.
From which country were the Directive Principles of State Policy of the Indian Constitution borrowed?
- A.The USSR
- B.The US
- C.Ireland
- D.China
Show answer
Correct answer: C. Ireland
Explanation
The correct answer is Ireland. The Directive Principles of State Policy in Part IV of the Constitution were modelled on the Irish Constitution. India also took two other features from Ireland: the nomination of members to the Rajya Sabha and the method of electing the President.
The other countries gave different features. The USSR is the source of the Fundamental Duties and of the ideal of social, economic and political justice in the Preamble. The United States gave the Fundamental Rights, judicial review, the independence of the judiciary and the impeachment of the President. China is not counted among the sources of the Indian Constitution at all. The pair most often confused is Rights and Principles: Fundamental Rights come from the USA, while the Directive Principles come from Ireland. A simple memory hook is "Rights from America, Directions from Ireland".
The concept of suspension of fundamental rights in the Indian Constitution has been taken from which country’s constitution?
- A.France
- B.Germany
- C.Russia
- D.Australia
Show answer
Correct answer: B. Germany
Explanation
The correct answer is Germany. The provision for suspending Fundamental Rights during an Emergency was taken from the Weimar Constitution of Germany. It is the only feature of the Indian Constitution usually traced to that source.
The other options are sources of different features. France gave the idea of a republic and the ideals of liberty, equality and fraternity in the Preamble. Russia, as the former USSR, gave the Fundamental Duties and the ideal of social, economic and political justice. Australia gave the Concurrent List, freedom of trade and commerce, and the joint sitting of the two Houses of Parliament. The emergency provisions as a whole are drawn largely from the Government of India Act, 1935, so a question on "emergency provisions" in general points there, while one on "suspension of Fundamental Rights during an Emergency" points to Germany. Read the wording carefully before choosing.
Who was the first to put forward the idea of a Constituent Assembly for India, in 1934?
- A.M.N. Roy
- B.Jawaharlal Nehru
- C.Mahatma Gandhi
- D.Subhas Chandra Bose
Show answer
Correct answer: A. M.N. Roy
Explanation
The correct answer is M.N. Roy. Manabendra Nath Roy, a pioneer of the communist movement in India, was the first to put forward the idea of a Constituent Assembly, in 1934. The Indian National Congress took up the idea and made it an official demand in 1935, and the British government accepted the demand in principle in the August Offer of 1940. The Assembly itself was finally formed in 1946 under the Cabinet Mission Plan.
Jawaharlal Nehru is the most tempting wrong answer, because he became closely identified with the demand and later moved the Objectives Resolution in the Assembly on 13 December 1946; but the idea was first put forward by Roy. Mahatma Gandhi and Subhas Chandra Bose are not credited with first proposing it. When a question uses the words "first" or "originally", it is usually testing exactly this: the difference between who proposed an idea and who carried it forward.
What was the total strength of the Constituent Assembly as fixed by the Cabinet Mission Plan?
- A.299
- B.389
- C.296
- D.395
Show answer
Correct answer: B. 389
Explanation
The correct answer is 389. The Cabinet Mission Plan of 1946 fixed the total strength of the Constituent Assembly at 389 seats: 296 for British India and 93 for the princely states. Of the 296 British Indian seats, 292 were for the eleven governors' provinces and 4 for the chief commissioners' provinces.
Every other option is a real number from the same chapter, placed to catch a hurried reader. 299 is the strength of the Assembly after Partition, when the members from the areas that went to Pakistan left. 296 is only the share of British India, without the princely states. 395 is not a count of members at all: it is the number of Articles in the Constitution as originally adopted. Questions on this topic often place these numbers side by side, so link each one to what it counts: 389 members at the start, 299 after Partition, 296 seats for British India and 395 original Articles.
