1947
Independence and Partition
Two dominions at midnight, and the largest forced migration in modern history. The date was advanced by ten months.
WhoJawaharlal Nehru · M. A. Jinnah · Lord Mountbatten · Sardar Patel
ImpactA sovereign India, a partitioned Punjab and Bengal, 562 states to integrate
Causes
- The Cabinet Mission’s failure and Direct Action Day, 1946
- Britain’s post-war fiscal and military exhaustion
- Mountbatten’s decision to advance the transfer to August 1947
Consequences
- Integration of 562 princely states under Patel and V. P. Menon
- The first Kashmir war, October 1947
- A Constituent Assembly that produced the Constitution by 1949
PeopleJawaharlal Nehru (First Prime Minister); Sardar Patel (Integrated the princely states); Lord Mountbatten (Last Viceroy)
For the examThe Mountbatten Plan of 3 June 1947 and the Indian Independence Act’s provisions are examined closely: the lapse of paramountcy, the right of the states to accede to either dominion, and the dominion status that continued until 26 January 1950. The three states that resisted — Junagadh, Hyderabad and Kashmir — and the instruments that settled each are the standard set.
Prelims pointerThe Radcliffe boundary awards were published on 17 August, two days after independence — the border was unknown on the day it took effect.

1947
The Mountbatten Plan sets the terms of Partition
Two dominions, provincial votes for Bengal and Punjab, a referendum for the Frontier, and a compressed ten-week timetable — the last Viceroy converts deadlock into a fixed, fast departure.
WhoLord Mountbatten · Sir Cyril Radcliffe
ImpactTurned Partition from a possibility into a fixed, dated plan, compressing what remained of the transfer into ten weeks
Causes
- The Cabinet Mission's grouping compromise had already collapsed, and Direct Action Day's violence had made continued deadlock look more dangerous than a rapid separation
- Attlee's 20 February 1947 statement had already committed Britain to withdraw by a fixed date, with or without an agreed settlement
- Congress had come to view partition as a painful but necessary alternative to prolonged civil conflict and administrative breakdown
Consequences
- Triggered one of the largest forced migrations in human history and communal violence that killed hundreds of thousands, as the compressed timetable left almost no time for orderly transition
- The Radcliffe Line, published only after independence itself, on 17 August 1947, left the new boundary genuinely unknown to millions of people on the day they became citizens of one country or the other
- The lapse of paramountcy launched the separate, sometimes contentious, process of princely state accession — Junagadh, Hyderabad and Jammu and Kashmir foremost among the disputed cases
PeopleLord Mountbatten (Last Viceroy; announced the Plan, 3 June 1947); Sir Cyril Radcliffe (Chaired the Boundary Commission that drew the Punjab and Bengal partition lines)
For the examPrelims separates the Mountbatten Plan (3 June 1947, the political decision), the Indian Independence Act (18 July 1947, its legal enactment) and the Radcliffe Line (published 17 August 1947, the actual boundary) as three distinct dated events. Mains uses the compressed timetable to explain the scale of Partition's human cost.
Prelims pointerThe Radcliffe Line was published two days AFTER independence, on 17 August 1947 — millions became citizens of India or Pakistan without yet knowing which side of the border they were on.

1950
The Constitution comes into force
Two years, eleven months and eighteen days of drafting produce the longest written constitution in the world — and a republic.
WhoB. R. Ambedkar · Rajendra Prasad · Constituent Assembly
ImpactA sovereign democratic republic with justiciable fundamental rights
Causes
- Constituent Assembly convened December 1946
- Objectives Resolution, 1947, and the Drafting Committee’s work
Consequences
- Universal adult franchise from the first general election, 1951-52
- Judicial review and fundamental rights
- A quasi-federal structure with a strong Union
PeopleB. R. Ambedkar (Chair, Drafting Committee); Rajendra Prasad (President of the Assembly)
For the examBorrowed provisions are asked every year: fundamental rights and judicial review from the United States, parliamentary government and the rule of law from Britain, directive principles from Ireland, emergency provisions from the Weimar constitution, the concurrent list from Australia and fundamental duties from the USSR. The committees and their chairs — Drafting under Ambedkar, Union Powers and Union Constitution under Nehru, Provincial Constitution and Advisory under Patel — are the other reliable set.
Prelims pointerThe Constitution was adopted on 26 November 1949 but commenced on 26 January 1950; a few articles on citizenship and elections came into force on the adoption date itself.

1956
States Reorganisation Act
India is redrawn along linguistic lines — fourteen states and six union territories replace the colonial provinces.
WhoFazl Ali Commission · Potti Sriramulu
ImpactThe linguistic state as the unit of Indian federalism
Causes
- Potti Sriramulu’s fast and death, 1952, and the creation of Andhra
- The Fazl Ali Commission report, 1955
Consequences
- Further bifurcations: Maharashtra and Gujarat 1960, Punjab and Haryana 1966
- Language as the durable basis of Indian state formation
PeoplePotti Sriramulu (Fasted for Andhra); Fazl Ali (Chaired the commission)
For the examThe commission sequence is examinable in order: the Dhar Commission of 1948 and the JVP Committee of 1949 both rejected linguistic reorganisation, then Andhra was conceded in 1953, then the Fazl Ali Commission of 1953 reported in 1955 and largely accepted the principle. The Seventh Amendment gave effect to the Act, and Article 3 remains the power under which states are still created.
Prelims pointerThe JVP Committee was Jawaharlal Nehru, Vallabhbhai Patel and Pattabhi Sitaramayya — the initials, not a department.
