Not every amendment matters equally for an exam — but these are the ones that keep coming back, and the ones below carry a sentence or two of why, not just what, because the reasoning is what actually gets tested in a well-set paper.

Memory hook — the Amendments Timeline as one chained story: "One nation reformed its Land (1st) and sorted its States (7th); then, in the crisis Seventies (24-25-26-36-39-42-44), Parliament and the courts fought — some rounds Parliament won, some the Court won back. The Eighties bought Discipline (52nd, anti-defection). The Nineties pushed power Downward — votes at 18 (61st), Delhi's own Assembly (69th), Panchayats and Municipalities (73rd/74th). The 2000s handed out Rights and tightened Rules — education (86th), a second commission for STs (89th), stricter anti-defection (91st). The 2010s built Institutions and taxed Together — co-ops (97th), NJAC struck down (99th), GST (101st), an OBC commission (102nd), EWS quota (103rd), SC/ST extension (104th). And the 2020s course-corrected — States got their SEBC power back (105th), and women got their reserved seats (106th)." Six decades, six one-word tags — Land/States, Crisis, Discipline, Downward, Rights/Rules, Institutions/Together, Course-corrected — walk the story and the amendment numbers fall into place around them.

Practice Recall. Before scanning the table below, try to name which amendment: (a) reversed Golaknath; (b) made GST possible; (c) is called the "Mini-Constitution"; (d) lowered the voting age; (e) is the corrective, post-Emergency amendment; (f) reserves seats for women.

Amendment	Year	What it did, and why
1st	1951	Added the Ninth Schedule and Articles 31A/31B to shield State land-reform laws after courts had begun striking down zamindari-abolition statutes as violating the then-Fundamental Right to property; also widened the restriction grounds under Article 19(2) after Romesh Thappar/Brij Bhushan exposed how narrowly speech restrictions were originally drafted; and enabled caste-based reservations in education by adding Article 15(4) after State of Madras v. Champakam Dorairajan had struck down a Madras communal-reservation order as violating Article 15(1).
4th	1955	Widened land-acquisition compensation rules under the original Article 31, giving legislatures more room to fix compensation without every valuation becoming a fresh court battle.
7th	1956	Gave effect to the States Reorganisation Act, 1956 by ending the old Part A/Part B/Part C State classification and repealing Article 238 (Part VII) altogether, replacing it with a uniform category of "States" and "Union Territories."
10th, 12th, 13th, 14th	1961–63	Integrated newly acquired or reorganised territories into the Union — Dadra & Nagar Haveli (10th), Goa/Daman/Diu after their 1961 liberation from Portuguese rule (12th), Nagaland as a full State (13th), and Puducherry along with Himachal Pradesh/Manipur/Tripura as Union Territories (14th).
24th	1971	Directly reversed Golaknath (1967) by expressly declaring Parliament's power under Article 368 to amend any part of the Constitution, Fundamental Rights included, and by stating that such a constitutional amendment is not "law" for the purposes of Article 13 — setting up the confrontation the Supreme Court would resolve, only partially in Parliament's favour, in Kesavananda Bharati two years later.
25th	1971	Curtailed the right to property further by replacing "compensation" with the vaguer "amount" for compulsorily acquired property, and inserted Article 31C to protect laws implementing DPSP Article 39(b)/(c) from challenge under Articles 14/19 — the provision Kesavananda and later Minerva Mills would spend years arguing over the outer limits of.
26th	1971	Abolished the privy purses and special privileges of former rulers of princely states, inserting Article 363A — a promise made at accession that the post-Emergency-era Indira Gandhi government decided the Republic's egalitarian and fiscal commitments could no longer sustain.
36th	1975	Made Sikkim a full State of the Indian Union (Article 2A, since omitted, and the 22nd Schedule item), completing its transition from an Indian protectorate.
39th	1975	Placed disputes regarding the election of the Prime Minister and the Speaker beyond the jurisdiction of any court — passed in the shadow of the Allahabad High Court's verdict against Indira Gandhi's own election; the clause was itself struck down by the Supreme Court in Indira Nehru Gandhi v. Raj Narain (1975) as violating the basic structure's guarantee of free and fair elections and judicial review.
42nd	1976	The "Mini-Constitution," passed during the Emergency with virtually no opposition scrutiny — added Socialist and Secular to the Preamble (and Integrity alongside Unity); inserted Fundamental Duties (Part IVA, Article 51A) on the Swaran Singh Committee's recommendation; created Part XIVA (Tribunals, Articles 323A–B); moved Education, Forests, Weights & Measures and the administration of justice from the State List to the Concurrent List; drastically curtailed judicial review of constitutional amendments and expanded Article 31C's DPSP-primacy — most of these last two moves were subsequently undone by the 44th Amendment and Minerva Mills (1980).
44th	1978	The corrective, post-Emergency amendment — reversed most of the 42nd Amendment's excesses; removed the right to property from Part III entirely (it survives only as the ordinary constitutional right under Article 300A in Part XII); made Articles 20 and 21 non-suspendable even during a National Emergency (Article 359); required a Cabinet's written recommendation, not the Prime Minister's word alone, before a National Emergency proclamation; and replaced "internal disturbance" with the tighter "armed rebellion" as Article 352's trigger, precisely to make a repeat of 1975 harder to engineer.
52nd	1985	Enacted the Anti-Defection Law, adding the Tenth Schedule, in response to rampant "Aaya Ram Gaya Ram" party-hopping through the 1960s–70s that had destabilised numerous State governments.
61st	1988	Lowered the voting age from 21 to 18 (Article 326), substantially widening the Indian electorate to bring young adults into the franchise.
69th	1991	Gave Delhi special Union Territory status with its own elected Assembly and Council of Ministers, inserting Article 239AA, while keeping Land, Police and Public Order with the Union — a compromise between full statehood (politically contentious, given Delhi's status as the national capital) and plain UT rule.
73rd / 74th	1992	Constitutionalised local self-government — Panchayats (Part IX, Eleventh Schedule) and Municipalities (Part IXA, Twelfth Schedule) respectively — converting what had been a discretionary DPSP aspiration (Article 40) into a mandatory, judicially enforceable structure with fixed terms, independent State Election Commissions, and guaranteed SC/ST/women's representation.
86th	2002	Inserted Article 21A, making free and compulsory education for children aged 6–14 a Fundamental Right, and simultaneously added the matching Fundamental Duty at Article 51A(k) obliging parents/guardians to provide that opportunity — the Right of Children to Free and Compulsory Education Act, 2009 later gave this right its detailed statutory content.
89th	2003	Split the single National Commission for SCs and STs into two separate constitutional bodies — a dedicated National Commission for Scheduled Tribes (Article 338A) alongside the existing one for Scheduled Castes (Article 338) — recognising that the two communities' developmental concerns had diverged enough to need separate institutional attention.
91st	2003	Tightened the Anti-Defection Law by deleting the "split" exception (which had let any breakaway faction of one-third or more of a party's legislators escape disqualification) and replacing it with a stricter two-thirds "merger" exception; also capped the size of Council of Ministers at 15% of a House's total membership, to curb the practice of oversized ministries used to reward defectors and coalition partners with berths.
97th	2011	Added Part IXB (Co-operative Societies, Articles 243ZH–ZT) and inserted the right to form co-operative societies into Article 19(1)(c) — later partly struck down (2021) for not securing the State-legislature ratification Article 368's proviso requires for provisions touching the State List.
99th	2014	Created the National Judicial Appointments Commission to replace the judiciary's own "collegium" system for appointing judges — struck down by the Supreme Court in 2015 as violating the basic structure's guarantee of judicial independence, restoring the collegium system that continues today.
101st	2016	Introduced the Goods and Services Tax, inserting Articles 246A, 269A and 279A — the single biggest indirect-tax reform since independence, replacing a patchwork of central excise, State VAT, octroi and dozens of other levies with one nationwide tax administered jointly by the Union and States through the GST Council.
102nd	2018	Elevated the National Commission for Backward Classes into a constitutional body (Article 338B) and inserted Article 342A, giving the President (and, controversially until the 105th Amendment clarified it, seemingly only the Union) the power to specify Socially and Educationally Backward Classes for each State/UT.
103rd	2019	Introduced a 10% reservation for Economically Weaker Sections (EWS) in education and public employment, inserting Articles 15(6) and 16(6) — notable for being the first reservation in India based purely on economic criteria rather than social/educational backwardness or caste, and upheld by the Supreme Court in 2022 by a narrow majority.
104th	2020	Extended the reservation of seats for SCs and STs in the Lok Sabha and State Assemblies for a further ten years, while simultaneously ending the President's/Governor's power to nominate Anglo-Indian members to the Lok Sabha and State Assemblies respectively, on the ground that the community's population had dwindled to the point that the original rationale for nomination no longer held.
105th	2021	Restored to State governments the explicit power to identify and notify their own lists of Socially and Educationally Backward Classes, after the Supreme Court's 2021 Maratha-reservation judgment had read Article 342A (as inserted by the 102nd Amendment) as vesting that power solely in the Union — a rapid legislative correction of a judicial reading Parliament considered unintended.
106th	2023	The Nari Shakti Vandan Adhiniyam — reserves one-third of seats for women in the Lok Sabha and State Legislative Assemblies (including within the SC/ST reserved-seat quota), to take effect only after the first delimitation exercise carried out following the next Census — meaning its actual implementation timeline remains a live subject of debate rather than an immediate change.
