This chapter presents a fleeting history of key changes in global trade and finance in the post-war period, organised around the themes of crisis and cooperation. The first section of the chapter discusses the key themes. The second section considers the emergence of the post-World War II Bretton Woods regime. The third section outlines the rise of private capital in the 1970s through to the debt crisis of the 1980s. The fourth section considers discussions of global financial architecture in the 1990s to the 2000s. The fifth section discusses changes in the last fifteen years, focusing on how the trade regime has stalled and the financial regime has been partially rolled back. Finally, the concluding section reflects on the ever-present need to foster cooperation in the global financial and trade architecture.

This chapter examines the politics of global poverty, inequality and development. The first section provides the background for our analysis of global poverty and inequality. Any meaningful discussion of poverty and inequality necessarily has to be in relation to development – which, as we show, is itself contested in theory and practice. The second section provides an outline of a relational perspective of global development. The third section focuses on the United Nations’ 2030 Sustainable Development Goals (SDGs) agenda. We conclude with some critical observations about the political significance of the relationship between development, poverty and inequality.

This chapter tracks the emergence and acceleration of global environmental problems since the end of World War II and delineates the field of global environmental politics. It also introduces the proposed new geological epoch called ‘the Anthropocene’ and the concept of planetary boundaries along with the key global environmental discourses of limits to growth/degrowth, sustainable development/green growth, ecological security and environmental justice. The chapter then examines how scholars working in the major theoretical traditions of International Relations – realism, liberalism, Critical Theory, constructivism and English School theory – have approached global environmental challenges. The conclusion reflects on the pivotal roles of the United States and China in tackling global warming.

This chapter examines the rise and growth of human rights. First, it discusses the historical development of human rights. Second, it outlines how human rights are understood today. Third, it explains how the liberal universalism that lies behind human rights has come up against cultural resistance. Finally, the chapter touches on some challenges that lie ahead in the struggle for human rights.

This chapter introduces an idea that has enjoyed a remarkable, if hotly contested, development in the post-Cold War era: humanitarian intervention. Based on a commitment to principles of humanity and respect for life, such action seeks to alleviate the unnecessary suffering caused by violent conflict through intervening in another state, with force under limited conditions. The chapter outlines the origins of humanitarianism and the history of humanitarian intervention before discussing the shift to the responsibility to protect (R2P). As world politics becomes ever more complex, debate about global responsibilities to protect suffering strangers will continue to shape the theory and practice of international relations. While abuse of human beings has not become less widespread, the preoccupation with COVID-19 and domestic priorities meant that little consideration was given to robust action against middle powers perpetrating mass atrocities in such places as Myanmar and Tigray, let alone against major powers in Ukraine and Xinjiang.

This chapter reflects on the tradition of Western political thought known as realism. Its main purpose is to identify who realists are, and to explain what realism is in the study of international relations. The first part of the chapter introduces students to some important thinkers, both ancient and modern, ascribed to the realist tradition. It also identifies two broad strands of realist thought: ‘classical’ and ‘structural’ or ‘neorealist’. The second part investigates attempts to conceive realism as a unified theory and practice of international relations. It highlights realism’s central concepts of the state and anarchy before reflecting on realism’s normative dimension.

Processes of arms control and disarmament remain relevant in a world where armed conflict between states is still highly visible in international politics, and where civil wars and domestic conflicts claim hundreds of thousands of lives every year. Much attention is focused on the need to control and eliminate weapons of mass destruction (WMDs), especially nuclear weapons, given the hugely destructive nature of these armaments, but controlling so-called ‘conventional weapons’ – those not classed as WMDs – is also important. Conventional weapons, especially small arms and light weapons, are responsible for most of the casualties we see today, even as arms control efforts have only recently begun to focus on these.

This chapter presents the outlines of a constructivist understanding of world politics. We begin with a discussion of state identity and explore how identity defines and bounds state actions. To illustrate this concept, we address issues central to the study of world politics: change, governance and security. Overall, our goal is to present a textured, layered understanding of the international realm based on a notion taken for granted in much of IR theory, meaning. Constructivism is the newest but perhaps the most dynamic of the main theories of international relations. Unlike liberalism and realism (see Chapters 2 and 3), which have taken their bearings from developments in economic and political theory, constructivism – like Critical Theory (see Chapter 4) – is rooted in insights from social theory (e.g. Berger and Luckmann 1967; Giddens 1984) and the philosophy of knowledge (Golinski 2005; Hacking 1999; Searle 1995).

This chapter gives an overview of the theory and practice of global climate politics. First, it provides a brief history of the politics of climate change as they play out in the international negotiations on the issue overseen by the United Nations . Second, it looks at the formal organisational and institutional structures that exist to manage the international community’s response to climate change. Third, it reviews the ways in which different theories of International Relations have been applied to climate change, assessing both their potential and their limitations. Finally, the conclusion offers some thoughts on the evolving nature of the ‘global’ governance of climate change.

This chapter explores the role of three global economic institutions (GEIs) in contemporary economic governance: the International Monetary Fund, (IMF), the World Bank and the World Trade Organisation (WTO). GEIs are key components of global economic governance, and their activities are central to the pursuit of accountability, efficiency and equity in the global economy. The impact of GEIs on states and societies is complex and widely varying assessments of the performance of these organisations can be found in the literature. Given the absence of theoretical consensus on the roles and functions of GEIs, the first part of the chapter examines competing perspectives on international organisations.

The first section of this chapter looks at how the two terms ‘migrant’ and ‘refugee’ came to be defined as distinct from each other in the context of the modern state. The second examines how states define and categorise refugees through laws that seek to contain and limit their flow. The third section is concerned with the consequences of limiting the definition of a refugee, which has led to an unequal burden between developed and developing states. The final section will canvass the various options presented to reduce the present imbalance where the vast majority of the world’s refugees eke out an existence in refugee camps in developing countries. Ultimately, this chapter seeks to demonstrate that the choices made by states in border protection become the key determinants of how refugees will be accepted. Adherence to international refugee law will not necessarily address all the problems associated with refugees, but nor will seeing refugees as unwanted intruders in contrast to ‘desirable’ migrants.

This chapter gives an overview of the long history, nature and significance of terrorism for international relations. It first addresses the topic’s recent prominence. Terrorism is by no means the most brutal type of violence, especially compared to wars in which states have killed millions of people. But it garners outsized attention through its symbolic nature. Only by educating ourselves can we rob terrorism of the source of its power. Second, it addresses key academic debates, which usually go back to the definition. The chapter argues that there are core areas of international agreement about what a terrorist act is, and that it can and should be distinguished from other types of violence. It also explains the lively debate over digital technology and the future of terrorism. Third, it lays out intellectual frameworks that help us to understand and analyse terrorism, including types of terrorism, historical patterns and the strategies used by terrorist groups. The chapter concludes with reflections about what is at stake in countering this type of illegitimate act.
