Chapter Summary

The sixth edition has 14 chapters in five parts and about 784 pages. The publisher describes its organising idea as the "3Is" framework, built on interests, interactions and institutions, which is used throughout to present students with puzzles about the world around them. Two new co-authors, Susan Hyde (UC Berkeley) and Stephanie Rickard (London School of Economics), are credited with the revised international political economy chapters and with newer topics such as human migration, human rights and the environment.

Part One, Chapters 1–2: What Shaped Our World? A Historical Introduction; Understanding Interests, Interactions, and Institutions

The foundations part pairs a historical introduction with the framework chapter. The publisher's "What Shaped Our World?" feature, which presents historical events through the three Is, shares its name with the title of Chapter 1, and Chapter 2 sets out the framework that the later parts apply.

Part Two, Chapters 3–6: Why Are There Wars?; Domestic Politics and War; International Institutions and War; Violence by Nonstate Actors: Civil War and Terrorism

Four chapters on war and peace. The titles suggest that war between states is approached from several angles in turn: why wars occur, the part played by domestic politics, and the part played by international institutions. The fourth chapter moves from states to nonstate actors, covering civil war and terrorism.

Part Three, Chapters 7–10: Cross-Border Flows of Goods and Services; Cross-Border Flows of Money and People; International Monetary Relations; Development: Causes of the Wealth and Poverty of Nations

The international political economy part. According to the publisher, Chapters 7 and 8 were significantly revised and retitled in this edition, and the publisher highlights discussion of how migration can conflict with states' interests and of cryptocurrency's influence on the financial system. Chapter 9 covers international monetary relations, and Chapter 10 asks why some nations are rich and others poor.

Part Four, Chapters 11–13: International Law, Norms, and Order; Human Rights; The Global Environment

Three chapters on transnational politics, all of which the publisher lists among the significantly revised chapters. They apply the framework to rules and norms among states, to human rights and to the environment.

Part Five, Chapter 14: Challenges to the Global Order

A single closing chapter looking ahead. The publisher says contemporary themes, including democratic backsliding, the rise of authoritarianism and the spread of populism, are explored across all chapters.

Key Concepts

Part One: Foundations (Chapters 1–2)

• Interests, interactions and institutions: the three elements of the framework introduced in Chapter 2.
• Historical context: the opening chapter's account of what shaped the world the book describes.

Part Two: War and Peace (Chapters 3–6)

• Causes of war: the question of Chapter 3.
• Domestic politics and war: the role of internal political actors, treated in Chapter 4.
• International institutions and war: how institutions bear on conflict (Chapter 5).
• Nonstate violence: civil war and terrorism.

Part Three: International Political Economy (Chapters 7–10)

• Cross-border flows: goods, services, money and people.
• International monetary relations: the subject of Chapter 9.
• Development: the causes of national wealth and poverty (Chapter 10).

Parts Four and Five: Transnational Politics and the Future (Chapters 11–14)

• International law and norms, human rights and the global environment: the three transnational topics.
• Challenges to the global order: the closing chapter.

Critical Analysis

Strengths

• One framework throughout. The book applies interests, interactions and institutions to every topic, so a student who masters Chapter 2 can carry the same tools from war to trade to human rights. The publisher stresses that the framework is thoroughly integrated through the book and its digital tools.
• Puzzle-led teaching. New chapter openers pose contemporary puzzles that frame each chapter's concepts, and the revised "How Do We Know?" feature presents research findings and data. According to the publisher, this gives students a way to analyse questions critically.
• Balanced coverage of security and political economy. Four chapters are devoted to war and peace and four to political economy, with three on transnational issues, so the book can serve as the main text for a course built around security and the international economy.
• Updated for current debates. The edition adds new international political economy material on migration and cryptocurrency, revised chapters on law, human rights and the environment, and attention to backsliding, authoritarianism and populism.
• Digital support. The Norton Illumine Ebook adds end-of-section Check Your Understanding questions with answer-specific feedback, and InQuizitive is an adaptive learning tool; the publisher also lists an instructor's manual, slides and a test bank.

Limitations

• One analytical lens. The contents list shows no chapters comparing the major schools of international relations theory, so students who need a survey of realism, liberalism, constructivism and critical approaches will need a theory-centred text alongside this one.
• Length. About 784 pages across 14 chapters is more than a single short course can cover, so selecting parts is necessary.
• Digital features tied to access codes. Norton UK lists access to the ebook and learning tools as included through a bind-in card, so students using older or used copies may need to buy access separately to reach the full set of study aids.

Where It Fits in the Course

This is the framework-driven, issue-centred introduction in the international-relations list. Sørensen and Møller's Introduction to International Relations and Global Politics is organised the other way round, by theory, with a chapter on each school, and works well as a companion for students who want the theories this book does not set out separately. Baylis, Smith and Owens's The Globalization of World Politics is an edited introductory text covering the history of the international system, the main theories, structures and processes, and global issues; it overlaps with this book in range but not in method. Reus-Smit's International Relations: A Very Short Introduction is a short first read organised around how political authority is arranged globally.

The two primary texts on the list serve as follow-ups: Waltz's Theory of International Politics is the statement of structural realism and Wendt's Social Theory of International Politics the foundational statement of constructivism, each a school this book treats through its framework rather than in a chapter of its own.

How to Use This Book

The book is aimed at undergraduates in a first course in international relations. The publisher's page lists no prerequisites.

A practical plan:

• Read first: Chapter 2, because every later chapter applies its framework, and Chapter 1 for the historical background.
• Core for most courses: Part Two on war and peace and Part Three on international political economy, which together make up eight of the 14 chapters.
• Select by emphasis: Part Four (law and norms, human rights, the environment) can be read as a block or by single chapter, and Chapter 14 works as a closing seminar reading.
• Use the learning features: the Check Your Understanding questions in the ebook and the "How Do We Know?" boxes are meant to turn the framework into a routine, so attempt them as each section is finished rather than after the chapter.
• Pair with theory: if the course covers IR theory, read the relevant chapters of a theory-centred textbook next to Chapters 2–6.
