NCERT Class 12 Political Science Part 2 Chapter 2: Era of One-Party Dominance

When India became a democracy in 1947, many people wondered whether the system would actually work in such a large and diverse country. Surprisingly, not only did it work, but one political party—the Indian National Congress—remained dominant for years. Chapter 2 of NCERT Class 12 Political Science Part 2, titled Era of One-Party Dominance, explains how Congress stayed in power during the early years after independence and why it was not just a political monopoly but part of the people’s imagination. The chapter also looks at the early elections, opposition parties, and democratic values during this period.

I wanted to write about this topic because it’s easy to think democracy means competition, but in India’s case, the same party winning again and again didn’t kill democracy—it helped stabilise it. Students often feel confused about how one-party dominance is different from dictatorship. That’s exactly why this chapter is important. It shows how democratic practices were followed even when there wasn’t strong opposition. I believe this is an important part of understanding India’s political journey, especially when today we often see coalition governments or regional parties coming into power. Understanding where we started helps us appreciate where we are now.

What This Chapter Covers

How Congress Dominated Indian Politics After Independence

  • The Indian National Congress won the first general elections in 1951-52 by a huge margin.
  • Congress was already popular due to its role in the freedom struggle, so it became the natural choice for many voters.
  • Leaders like Jawaharlal Nehru, Sardar Patel, and Maulana Azad brought credibility and stability to the party.
  • Congress functioned like a broad platform, with space for different views and factions under one umbrella.

First Three General Elections

195747.8%371/494CPI
196244.7%361/494Swatantra Party
  • Even with just 45% vote share, Congress won most seats due to the ‘first-past-the-post’ electoral system.
  • No other party was strong enough to challenge Congress nationally during these years.

Was It Really a One-Party System?

  • Yes, Congress was dominant, but no, it wasn’t undemocratic.
  • Elections were free and fair.
  • Opposition parties like CPI, Socialist Party, and Bharatiya Jana Sangh (precursor to BJP) did exist and won seats, though not in large numbers.
  • Congress also had internal democracy—different viewpoints existed within the party itself.

Role of Opposition

  • The presence of opposition parties, though weak, kept democratic debate alive.
  • They raised questions in Parliament and offered alternative policies.
  • Slowly, opposition parties started gaining strength in states like Kerala and Tamil Nadu.

Congress as a Social Coalition

  • Congress managed to unite people across regions, castes, and classes.
  • It did not represent a single ideology but worked like a rainbow platform, taking everyone along.
  • This helped maintain national unity in the early fragile years after independence.

Why Understanding This Chapter Matters

  • Helps students see how Indian democracy developed step by step.
  • Makes us aware of how even dominance can co-exist with democracy.
  • Explains why a strong opposition is important and how it slowly emerged.
  • Connects history with the present—today’s multi-party system is rooted in this early phase.

NCERT Class 10 Math Chapter 14 प्रायिकता (Probability) introduces students to the concept of chance and likelihood of events. In this chapter, students learn how to calculate the probability of simple events using the formula P(E) = Number of favourable outcomes ÷ Total number of outcomes. The chapter deals with real-life examples like tossing a coin, rolling a dice, or drawing cards, which makes the subject more interesting and practical. Since probability questions are common in board exams and are generally considered easy, this chapter is highly important for scoring well.

I am writing about this topic because probability is not only an important part of the Class 10 syllabus but also a concept that students will use in higher studies and real life. From predicting weather conditions to calculating risks in business, probability plays a key role. Many students initially find it confusing, but NCERT presents it in a simple and easy-to-understand manner. By practising from the NCERT book, students can build a strong foundation and develop confidence in solving probability problems. Having the PDF makes it easier for learners to access the chapter anytime, revise formulas, and attempt practice questions before exams.

Key Concepts in Chapter 14 प्रायिकता

This chapter focuses on:

  • The definition of probability
  • Probability of simple events
  • Formula: P(E) = Number of favourable outcomes ÷ Total number of outcomes
  • Practical examples using coins, dice, and cards
  • Application-based word problems

Example Problem

If a dice is thrown once, what is the probability of getting an even number?

  • Total outcomes = 6 (1, 2, 3, 4, 5, 6)
  • Favourable outcomes = 3 (2, 4, 6)
  • Probability = 3/6 = 1/2

Such examples make the concept clear and help students apply the formula correctly.
