Chapter Overview

The Preamble (प्रस्तावना) states what the Constitution of India is for. Its salient features (प्रमुख विशेषताएँ) show how it is built. Its sources (स्रोत) explain where those features came from. Together they form the base of the whole Polity syllabus: every later chapter, from Fundamental Rights to Centre–State relations, is one of these features examined in depth.

What You’ll Learn

By the end of this chapter, you will be able to:

Recite the Preamble in order and explain each key word: sovereign, socialist, secular, democratic, republic, justice, liberty, equality, fraternity
State what the 42nd Amendment (1976) changed and what the Supreme Court decided about it in November 2024
Trace the “is the Preamble part of the Constitution?” question from Berubari (1960) to Kesavananda Bharati (1973)
Give the size of the Constitution in 1950 and today, and the amendments that added the four new schedules
Explain the three methods of amendment, the “federal with a unitary bias” debate and the basic structure doctrine
Match each borrowed feature to its source (1935 Act, UK, US, Ireland, Canada, Australia and others)
Write balanced Mains answers on the Preamble’s philosophy, Indian federalism and the “borrowed constitution” charge, with a Chhattisgarh angle

Prerequisites

Constitutional Development (1773–1950) — the Government of India Act, 1935 and the Constituent Assembly that drafted the Constitution

Where It Is Asked

Paper	What to expect
Prelims P-I (Part 1, India GS)	Fact-based MCQs: words of the Preamble and their order, the 42nd Amendment, Berubari vs Kesavananda, number of parts and schedules, which amendment added which schedule, federal vs unitary features. “Source of a feature” questions usually come as match-the-following
Mains P-III (GS-I), Constitution section	Short answers (“Is the Preamble part of the Constitution?”, “rigid or flexible?”) and longer analytical answers (philosophy of the Preamble, “federal in form, unitary in spirit”, “a bag of borrowings”, the basic structure doctrine)

Exam focus

High-yield: the three words added in 1976 (Socialist, Secular, Integrity); Berubari (1960) vs Kesavananda (1973); 395/22/8 in 1950; schedules 9–12 and the amendments that added them; Art 368 methods; Ireland = DPSP, Canada = strong Centre, Australia = Concurrent List.
Common mistakes: saying the Preamble was never amended; calling India a “federation” (Art 1 says “Union of States”); swapping Canada and Australia; mixing up the Eleventh (Panchayats) and Twelfth (Municipalities) Schedules.
Chhattisgarh angle for Mains: the state was created in 2000 by an ordinary law under Art 3; CGPSC is a constitutional body under Art 315; the Fifth Schedule governs its Scheduled Areas; Ghanshyam Singh Gupta of Durg chaired the Hindi translation committee of the Constitution.
