Charles Maier offers a new narrative of the long twentieth century, focused on institutions that shaped politics and societies: project-states, driven by democratic or authoritarian ideologies; capital; and advocates of apolitical values, such as health, human rights, and international law. In this we discern the unfolding of our own troubled time.

Throughout history, human societies have been organized preeminently as territories—politically bounded regions whose borders define the jurisdiction of laws and the movement of peoples. At a time when the technologies of globalization are eroding barriers to communication, transportation, and trade, Once Within Borders explores the fitful evolution of territorial organization as a worldwide practice of human societies. Master historian Charles S. Maier tracks the epochal changes that have defined territories over five centuries and draws attention to ideas and technologies that contribute to territoriality’s remarkable resilience. Territorial boundaries transform geography into history by providing a framework for organizing political and economic life. But properties of territory—their meanings and applications—have changed considerably across space and time. In the West, modern territoriality developed in tandem with ideas of sovereignty in the seventeenth century. Sovereign rulers took steps to fortify their borders, map and privatize the land, and centralize their sway over the populations and resources within their domain. The arrival of railroads and the telegraph enabled territorial expansion at home and abroad as well as the extension of control over large spaces. By the late nineteenth century, the extent of a nation’s territory had become an index of its power, with overseas colonial possessions augmenting prestige and wealth and redefining territoriality. Turning to the geopolitical crises of the twentieth century, Maier pays close attention to our present moment, asking in what ways modern nations and economies still live within borders and to what degree our societies have moved toward a post-territiorial world.

Thomas Hobbes laid the theoretical groundwork of the nation-state in Leviathan, his tough-minded treatise of 1651. Leviathan 2.0 updates this classic account to explain how modern statehood took shape between the mid-nineteenth and mid-twentieth centuries, before it unraveled into the political uncertainty that persists today. Modern states were far from immune to the modernizing forces of war, technology, and ideology. From 1845 to 1880, the United States, Canada, Mexico, and Argentina were all reconstituted through territorial violence. Europe witnessed the unification of Germany and Italy, while Asian nations such as Japan tried to mitigate foreign incursions through state-building reforms. A global wave of revolution at the turn of the century pushed the modernization process further in China, Russia, Iran, and Ottoman Turkey. By the late 1930s, with the rise of the Soviet Union and Nazi Germany, the momentum of history seemed to shift toward war-glorifying totalitarian states. But several variants of the modern state survived World War II: the welfare states of Western democracies; single-party socialist governments; and governments dominated by the military, especially prevalent in Latin America, Asia, and the Middle East. Toward the end of the twentieth century, all of these forms stood in growing tension with the transformative influences of globalized capitalism. Modern statehood recreated itself in many ways, Charles S. Maier concludes, but finally had to adopt a precarious equilibrium with ever more powerful economic forces.

Contemporary America, with its unparalleled armaments and ambition, seems to many commentators a new empire. Others angrily reject the designation. What stakes would being an empire have for our identity at home and our role abroad? A preeminent American historian addresses these issues in light of the history of empires since antiquity. This elegantly written book examines the structure and impact of these mega-states and asks whether the United States shares their traits and behavior. Eschewing the standard focus on current U.S. foreign policy and the recent spate of pro- and anti-empire polemics, Charles S. Maier uses comparative history to test the relevance of a concept often invoked but not always understood. Marshaling a remarkable array of evidence—from Roman, Ottoman, Moghul, Spanish, Russian, Chinese, and British experience—Maier outlines the essentials of empire throughout history. He then explores the exercise of U.S. power in the nineteenth and twentieth centuries, carefully analyzing its economic and strategic sources and the nation’s relationship to predecessors and rivals. To inquire about empire is to ask what the United States has become as a result of its wealth, inventiveness, and ambitions. It is to confront lofty national aspirations with the realities of the violence that often attends imperial politics and thus to question both the costs and the opportunities of the current U.S. global ascendancy. With learning, dispassion, and clarity, Among Empires offers bold comparisons and an original account of American power. It confirms that the issue of empire must be a concern of every citizen.

In a brilliantly conceived book, Jeremi Suri puts the tumultuous 1960s into a truly international perspective in the first study to examine the connections between great power diplomacy and global social protest. Profoundly disturbed by increasing social and political discontent, Cold War powers united on the international front, in the policy of detente. Though reflecting traditional balance of power considerations, detente thus also developed from a common urge for stability among leaders who by the late 1960s were worried about increasingly threatening domestic social activism. In the early part of the decade, Cold War pressures simultaneously inspired activists and constrained leaders; within a few years activism turned revolutionary on a global scale. Suri examines the decade through leaders and protesters on three continents, including Mao Zedong, Charles de Gaulle, Martin Luther King Jr., Daniel Cohn-Bendit, and Aleksandr Solzhenitsyn. He describes connections between policy and protest from the Berkeley riots to the Prague Spring, from the Paris strikes to massive unrest in Wuhan, China. Designed to protect the existing political order and repress movements for change, detente gradually isolated politics from the public. The growth of distrust and disillusion in nearly every society left a lasting legacy of global unrest, fragmentation, and unprecedented public skepticism toward authority.

Of all the horrors of the last century—perhaps the bloodiest century of the past millennium—ethnic cleansing ranks among the worst. The term burst forth in public discourse in the spring of 1992 as a way to describe Serbian attacks on the Muslims of Bosnia-Herzegovina, but as this landmark book attests, ethnic cleansing is neither new nor likely to cease in our time. Norman Naimark, distinguished historian of Europe and Russia, provides an insightful history of ethnic cleansing and its relationship to genocide and population transfer. Focusing on five specific cases, he exposes the myths about ethnic cleansing, in particular the commonly held belief that the practice stems from ancient hatreds. Naimark shows that this face of genocide had its roots in the European nationalism of the late nineteenth century but found its most virulent expression in the twentieth century as modern states and societies began to organize themselves by ethnic criteria. The most obvious example, and one of Naimark’s cases, is the Nazi attack on the Jews that culminated in the Holocaust. Naimark also discusses the Armenian genocide of 1915 and the expulsion of Greeks from Anatolia during the Greco–Turkish War of 1921–22; the Soviet forced deportation of the Chechens-Ingush and the Crimean Tatars in 1944; the Polish and Czechoslovak expulsion of the Germans in 1944–47; and Bosnia and Kosovo. In this harrowing history, Naimark reveals how over and over, as racism and religious hatreds picked up an ethnic name tag, war provided a cover for violence and mayhem, an evil tapestry behind which nations acted with impunity.

Fatal Misconception is the disturbing story of our quest to remake humanity by policing national borders and breeding better people. As the population of the world doubled once, and then again, well-meaning people concluded that only population control could preserve the “quality of life.” This movement eventually spanned the globe and carried out a series of astonishing experiments, from banning Asian immigration to paying poor people to be sterilized. Supported by affluent countries, foundations, and non-governmental organizations, the population control movement experimented with ways to limit population growth. But it had to contend with the Catholic Church’s ban on contraception and nationalist leaders who warned of “race suicide.” The ensuing struggle caused untold suffering for those caught in the middle—particularly women and children. It culminated in the horrors of sterilization camps in India and the one-child policy in China. Matthew Connelly offers the first global history of a movement that changed how people regard their children and ultimately the face of humankind. It was the most ambitious social engineering project of the twentieth century, one that continues to alarm the global community. Though promoted as a way to lift people out of poverty—perhaps even to save the earth—family planning became a means to plan other people‘s families. With its transnational scope and exhaustive research into such archives as Planned Parenthood and the newly opened Vatican Secret Archives, Connelly’s withering critique uncovers the cost inflicted by a humanitarian movement gone terribly awry and urges renewed commitment to the reproductive rights of all people.
