This chapter examines how thinking about international relations (IR) has evolved since IR became an academic subject around the time of the First World War. The focus is on four established IR traditions: realism, liberalism, International Society, and International Political Economy (IPE). The chapter first considers three major debates that have arisen since IR became an academic subject at the end of the First World War: the first was between utopian liberalism and realism; the second between traditional approaches and behaviouralism; the third between neorealism/neoliberalism and neo-Marxism. There is an emerging fourth debate, that between established traditions and post-positivist alternatives. The chapter concludes with an analysis of alternative approaches that challenge the established traditions of IR, and with a discussion about criteria for good theory in IR.

This chapter examines the three most important classical theories within the field of International Political Economy (IPE): mercantilism, economic liberalism, and neo-Marxism. It considers the relationship between politics and economics, and between states and markets in world affairs, that IR has to be able to grasp. It suggests that IPE is about wealth, poverty, and power, about who gets what in the international economic and political system. The outlook of mercantilism has much in common with realism, while economic liberalism is an addition to liberalism. Mercantilism and economic liberalism thus represent views on IPE that are basically realist and liberal. The chapter concludes with a discussion about the original theoretical position of Marxism and how this has inspired neo-Marxist IPE theories.

This chapter examines the social constructivist theory of IR. It first discusses the rise of social constructivism and why it has established itself as an important approach in IR. It then considers constructivism as social theory, and more specifically as both a meta-theory about the nature of the social world and as a set of substantial theories of IR. Several examples of constructivist IR theory are presented, followed by reflections on the strengths and weaknesses of the constructivist approach. The chapter proceeds by exploring constructivist theories of international relations, focusing on cultures of anarchy, norms of International Society, the power of international organizations, a constructivist approach to European cooperation, and domestic formation of identity and norms. The chapter concludes with an analysis of some of the major criticisms of constructivism and by emphasizing internal debates within constructivism.

This chapter examines four major issues in International Political Economy (IPE). The first concerns power and the relationship between politics and economics, and more specifically whether politics is in charge of economics or whether it is the other way around. The second issue deals with development and underdevelopment in developing countries. The third is about the nature and extent of economic globalization, and currently takes places in a context of increasing inequality between and inside countries. The fourth and final issue concerns how to study the real world from an IPE perspective and it pits the hard science American School against the more qualitative and normative British School.

This final chapter addresses a really big question: are international relations heading towards order or chaos? To answer this question, it interrogates the different IR theories presented in previous chapters. An initial section provides a conceptual map, based on a review of different understandings of the concept of world order. The chapter proceeds by discussing the effect of the rise of authoritarian power such as China, new challenges in established democracies, fragile states in the Global South, and the governance provided by international institutions. The chapter ends by arguing that the glass is at the same time half-full and half-empty: the world faces new and formidable challenges and we are very far from meeting current aspirations for world order; at the same time, global relations are much more ordered than they used to be just a few generations ago—and things are far better than many pessimists claim.

Introduction to International Relations provides a concise introduction to the principal international relations theories and approaches, and explores how theory can be used to analyse contemporary issues. Throughout the text, the chapters encourage readers to consider the strengths and weaknesses of the theories presented, and the major points of contention between them. In so doing, the text helps you to build a clear understanding of how major theoretical debates link up with each other, and how the structure of the discipline of international relations is established. The book places a strong emphasis throughout on the relationship between theory and practice, carefully explaining how theories organise and shape our view of the world. It also shows how a historical perspective can often refine theories and provide a frame of reference for contemporary problems of international relations. Topics include realism, liberalism, International Society, International Political Economy, social constructivism, post-positivism in international relations, major issues in IPE and IR, and foreign policy. Each chapter ends by discussing how different theories have attempted to integrate or combine international and domestic factors in their explanatory frameworks. The final chapter is dedicated to discussing the state of the world: are we seeing world chaos or world order? The text is accompanied by an Online Resource Centre, which includes: short case studies, review questions, annotated web links, and a flashcard glossary.

This chapter examines the realist tradition in international relations (IR), which is best seen as a research programme with several approaches using a common starting point. It highlights an important dichotomy in realist thought between classical realism and contemporary realism, including strategic and structural approaches. After describing the elements of realism, the chapter discusses the international thought of three outstanding classical realists of the past: Thucydides, Niccolò Machiavelli, and Thomas Hobbes. It then analyses the classical realist thought of Hans J. Morgenthau, along with strategic realism, neorealism, and neoclassical realism. Special attention is devoted to the defensive realism of Kenneth Waltz and the offensive realism of John Mearsheimer. Furthermore, the chapter looks at the recent theoretical debate among realist IR scholars concerning the relevance of the balance of power concept and it shows that realists often disagree among themselves. The chapter concludes with an overview of how the different realist theories treat international and domestic factors.

This chapter examines four of the most important issues in international relations (IR): climate change, international terrorism, religion, and balance and hegemony in world history. It also considers the different ways in which these issues are analysed by the various theories presented in this book. The chapter begins with a discussion of what the issue is about in empirical terms, the problems raised and why they are claimed to be important, and the relative significance of the issue on the agenda of IR. It then explores the nature of the theoretical challenge that the issues present to IR and how classical and contemporary theories handle the analysis of these issues. The chapter addresses how climate change has become a first order challenge of international relations and IR theories, Samuel Huntington’s ‘clash of civilizations’ thesis, the influence of religion on politics, and how throughout history different state systems have come to equilibrate on either balance of power or hegemony.

This chapter examines post-positivist approaches in international relations (IR). Post-positivism rejects any claim of an established truth valid for all. Instead, its focus is on analysing the world from a large variety of political, social, cultural, economic, ethnic, and gendered perspectives. The chapter considers three of the most important issues taken up by post-positivist approaches: post-structuralism, which is concerned with language and discourse; postcolonialism, which adopts a post-structural attitude in order to understand the situation in areas that were conquered by Europe, particularly Africa, Asia, and Latin America; and feminism, which argues that women are a disadvantaged group in the world, in both material terms and in terms of a value system which favours men over women. It also reflects on recent calls for ‘Global IR’, where voices from outside of Western research environments are heard. The chapter concludes with an overview of criticisms against post-positivist approaches and the post-positivist research programme.

This chapter examines the liberal tradition in international relations (IR). It first considers the basic liberal assumptions, including a positive view of human nature and the belief that IR can be cooperative rather than conflictual. In their conceptions of international cooperation, liberal theorists emphasize different features of world politics. The chapter explores the ideas associated with four strands of liberal thought, namely: sociological liberalism, interdependence liberalism, institutional liberalism, and republican liberalism. It also discusses the debate between proponents of liberalism and neorealism, and it identifies a general distinction between weak liberal theories that are close to neorealism and strong liberal theories that challenge neorealism. Finally, it reviews the liberal view of world order and the notion that there is a ‘dark’ side of democracy.

This chapter examines theories and approaches involved in foreign policy analysis. Foreign policy analysis (FPA) is concerned with the study of the management of external relations and activities of nation-states, as distinguished from their domestic policies. The chapter first explains the concept of foreign policy before discussing various approaches to foreign policy analysis. It then evaluates the arguments of major theories by using a ‘level-of-analysis’ approach that addresses the international system level, the nation-state level, and the level of the individual decision maker. It also presents a case-study on the Gulf War to illustrate how insights from various approaches to foreign policy analysis can be brought together. The chapters ends with reflections on Donald Trump’s foreign policy and a discussion of how FPA theories have combined domestic and international factors.

This chapter examines the International Society tradition of international relations (IR). International Society, also known as the ‘English School’, is an approach to world politics that places emphasis on international history, ideas, structures, institutions, and values. After providing an overview of International Society’s basic assumptions and claims, the chapter considers the three traditions associated with the leading ideas of the most outstanding classical theorists of IR such as Niccolò Machiavelli and Immanuel Kant: realism, rationalism, and revolutionism. It then explores International Society’s views regarding order and justice, world society, statecraft and responsibility, and humanitarian responsibility and war; as well as how International Society scholars have used a historical approach to understand earlier international systems and the development of international society. It also discusses several major criticisms against the International Society approach to IR and concludes with an overview of the research agenda of International Society after the Cold War.

A note on foreign policy experts and ‘think tanks’ is included to highlight the extent of research on the subject which extends well beyond universities.

Chapter 7 addresses film censorship in the South, and places this history in the larger context of the American film industry as a whole. From early boxing films such as the Johnson-Jeffries fight of 1910, which led southern politicians to ban interracial boxing films (and, in some cases, all boxing films) to the prodigious work of individual southern censors including Lloyd T. Binford of Memphis and Evan R. Chesterman of the State of Virginia, this history reveals the embeddedness of Jim Crow ideology within all sorts of film institutions. In the years after World War II, when film censorship practices came under greater scrutiny and legal threat, the work of southern film censors largely petered out, anticipating some of the coming confrontations of the Civil Rights Movement.

This conclusion settles on 1948 as an apt, if provisional, endpoint for the history of the southern cinema, citing several key events of that year: the presidential election and its exposure of deepening racial fissures, the US Supreme Court’s landmark decision in United States v. Paramount Pictures, Inc., and the launch of widespread commercial television programming. D. W. Griffith’s death, the last of James Agee’s brilliant film criticism, and the publication of William Faulkner’s novel Intruder in the Dust also made 1948 significant in these contexts of region, race, and media, suggesting the major events and transformations to come in the near future—not the least of which was the Civil Rights Movement.

Fade In, Crossroads is a history of the relations between southerners and motion pictures from the silent era to midcentury. In providing a narrative of the South’s contributions to the film medium from the late nineteenth century through the golden age of Hollywood, it considers the many southerners who worked as inventors, executives, filmmakers, screenwriters, performers, and critics during this period. It explores early production centers within the South as well as the effects of the migration of millions of black and white southerners beyond the region to such destinations as Los Angeles, where they made inroads in the growing film industry. It is also the story of how the rise and fall of the American film industry coincided with the rise and fall of the South’s most important modern product and export—Jim Crow segregation. This work looks at important southern historical legacies on film: the Civil War film tradition (which includes the two most successful films of all time, The Birth of a Nation and Gone with the Wind); the notorious tradition of lynching films during an era of prolific lynching in the South; and the remarkable race film industry, whose independent African American filmmakers forged an important cinematic tradition in response to the racial limitations of both the South and Hollywood. It also examines the activities of southern censorship officials, who utilized the medium in the service of Jim Crow, and traces the influence of film on future Civil Rights Movement figures.

Chapter 3 is devoted to the film-related activities of southern literary figures. From nineteenth-century writers including Mark Twain and Harriet Beecher Stowe (not a southerner by birth, but, as author of Uncle Tom’s Cabin, a huge influence on southern literary history) to modern figures like Thomas Dixon, William Faulkner, Lillian Hellman, and the Nashville Agrarians, the southern literary tradition made myriad contributions to film. Faulkner’s screenwriting work provides perhaps the most engaging example. Meanwhile, the efforts of African American writers to make similar contributions were limited by the hard facts of Jim Crow, leaving such important figures as Richard Wright and Langston Hughes, among many others, to generate their own opportunities, often abroad, in a far more uneven fashion. Black film critics like Lester A. Walton also emerged as important literary figures.

Chapter 6 places the African American race film industry into the context of southern history as well as the studio system. Hollywood’s combination of derivative typecasting of African American characters and strict segregation in institutional practices evidenced a broad neglect of black topics, themes, and audiences, and well before the studio system’s consolidation, African American filmmakers showed an interest in the possibilities of the medium. In the years after World War I especially, a tradition of African American filmmaking sought to redress the commercial, aesthetic, and political deficiencies of the mainstream film industry. Through figures such as Oscar Micheaux, Spencer Williams, and others, race film played a number of key roles in a black culture within and beyond the South, even as civil rights figures like the NAACP’s Walter F. White attempted, with modest success, to bring about reform within Hollywood.

This introduction lays out the topic, arguments, and structure of the entire book. It begins with a brief case study of Annie Minerva Turnbo Malone’s use of motion pictures as part of her growing business empire in the early twentieth century, argues for the centrality of motion pictures to modern southern history and the influence of the South on the half-century development of the film industry from its beginnings to the early postwar era, and identifies the topics of each chapter to follow.

Chapter 5 examines lynching, a longstanding practice in the United States that became more regionally associated with the South in the late nineteenth century, as a force in film history from the earliest days of the medium through a cycle of anti-lynching films during the years around midcentury. Paradoxically, the Western genre is important here, absorbing many of the common rituals and generating a powerful ideological defense of lynching. During different periods across this half-century, different attitudes about lynching led to a variety of film representations, culminating with a number of films in the late 1930s and beyond questioning both lynching and its cinematic traces.

Chapter 1 surveys the contributions of southerners to film with an emphasis on activity within the South. Linking the early development of the medium to post-Reconstruction “New South” ideology and grounding it in the efforts of several early innovators from Virginia, this chapter covers a number of important events and movements: the Spanish-American War of 1898, the emergence of Jacksonville, Florida as a major production center in the 1910s, the diverse history of North Carolina’s early film cultures (Asheville as a production center, Karl Brown’s Stark Love, diverse filmmaking ventures throughout the state, the state’s popular education film program, the brilliant career of town documentarian H. Lee Waters), and the long career of King Vidor.

Chapter 4 deals with the cinematic legacies of the Civil War, from very early documentary films featuring Confederate Memorial Days and battlefield reenactments to the two most significant feature films in the history of American motion pictures: The Birth of a Nation and Gone with the Wind. D. W. Griffith’s singular career, and his enduring influence of the institutional structure of the medium and industry, is a central presence here, while the extraordinary popularity of Gone with the Wind as novel and film provided a sense of continuity with earlier Civil War films sympathetic to the Confederacy and its partisans.

This chapter examines the three most important classical theories within the field of International Political Economy (IPE): mercantilism, economic liberalism, and neo-Marxism. It also considers the relationship between politics and economics, and between states and markets in world affairs, that IR has to be able to grasp.

This chapter examines the realist tradition in international relations (IR). It highlights an important dichotomy in realist thought between classical realism and contemporary realism, including strategic and structural approaches. It also considers both classical and social scientific strands of realist thought. After describing the elements of realism, the chapter discusses the international thought of three outstanding classical realists of the past: Thucydides, Niccolò Machiavelli, and Thomas Hobbes. It then analyses the classical realist thought of Hans J. Morgenthau, along with strategic realism and neorealism. Furthermore, it looks at the recent theoretical debate among realist IR scholars concerning the relevance of the balance of power concept, as well as two critiques of realist doctrine: an International Society critique and a revisionist and emancipatory critique. The chapter concludes with an overview of the prospects for the realist tradition as a research programme in IR.

This chapter examines the social constructivist theory of International Political Economy (IPE). It first discusses the rise of social constructivism and why it has established itself as an important approach in IR. It then considers constructivism as social theory, and more specifically as both a meta-theory about the nature of the social world and a substantial theory of IR.

This chapter examines four of the most important contemporary issues in international relations (IR): international terrorism, religion, the environment, and new patterns of war and peace. It also considers the different ways in which these issues are analysed by the various theories presented in this book. The chapter begins with a discussion of what the issue is about in empirical terms, the problems raised and why they are claimed to be important, and the relative significance of the issue on the agenda of IR. It then explores the nature of the theoretical challenge that the issues present to IR and how classical and contemporary theories handle the analysis of these issues. The chapter addresses Samuel Huntington's ‘clash of civilizations’ thesis, the influence of religion on politics, opposing views on the environment issue, and how new patterns of war and peace are linked to changes in statehood.

This chapter examines post-positivist approaches in international relations (IR). Post-positivism rejects any claim of an established truth valid for all. Instead, its focus is on analysing the world from a large variety of political, social, cultural, economic, ethnic, and gendered perspectives. The chapter considers three of the most important issues taken up by post-positivist approaches: post-structuralism, which is concerned with language and discourse; post-colonialism, which adopts a post-structural attitude in order to understand the situation in areas that were conquered by Europe, particularly Africa, Asia, and Latin America; and feminism, which argues that women are a disadvantaged group in the world, in both material terms and in terms of a value system which favours men over women. The chapter concludes with an overview of criticisms against post-positivist approaches and the post-positivist research programme.

This chapter examines three important debates in International Political Economy (IPE). The first debate concerns power and the relationship between politics and economics, and more specifically whether politics is in charge of economics or whether it is the other way around. The second debate deals with development and underdevelopment in developing countries. The third debate is about the nature and extent of economic globalization, and currently takes places in a context of increasing inequality between and inside countries. This debate is also informed by the serious financial crisis of 2008 and has raised questions regarding the viability of the current model of capitalism in the United States and Western Europe.

This chapter examines the International Society tradition of international relations (IR). International Society, also known as the ‘English School’, is an approach to world politics that places emphasis on international history, ideas, structures, institutions, and values. After providing an overview of International Society's basic assumptions and claims, the chapter considers the three traditions associated with the leading ideas of the most outstanding classical theorists of IR such as Niccolò Machiavelli and Immanuel Kant: realism, rationalism, and revolutionism. It then explores International Society's views regarding order and justice, empire and world society, statecraft and responsibility, and humanitarian responsibility and war. It also discusses several major criticisms against the International Society approach to IR and concludes with an overview of the current research agenda of International Society.

This chapter examines how thinking about international relations (IR) has evolved since IR became an academic subject around the time of the First World War. The focus is on four established IR traditions: realism, liberalism, International Society, and International Political Economy (IPE). The chapter first considers three major debates that have arisen since IR became an academic subject at the end of the First World War: the first was between utopian liberalism and realism; the second between traditional approaches and behaviouralism; the third between neorealism/neoliberalism and neo-Marxism. There is an emerging fourth debate, that between established traditions and post-positivist alternatives. The chapter concludes with an analysis of alternative approaches that challenge the established traditions of IR.
