In 1917 Congress passed the Trading with the Enemy Act to prevent trade with Germany and the Central Powers. It was a wartime law designed for wartime conditions but one that, over the course of the following century, took on a secret, surprising life of its own. Eventually it became the basis for a project of worldwide economic sanctions applied by the United States at the discretion of the president during times of both war and peace. This article traces the history of the law in order to explore how the expansion of American power in the twentieth century required a transformation of the American state and the extensive use of executive powers justified by repeated declarations of national emergency.

This essay explores the internationalist vision of Wendell Willkie during World War II, especially as illustrated in his 1943 bestseller, One World. Willkie proposed three mid-century popular geographies of the globe—ways of seeing the relationship between the United States and the world in the context of the expanding ambit of American power and influence. Willkie offered a universal view of the planet, one that envisioned a new kind of global space free of borders; a depiction of imperial power contested, which critiqued the racial thinking that underpinned conquest abroad and discrimination at home; and a view of imperial power obscured, which left unmapped the actual contours of already existing American empire, a dilemma revealed by the omission of the Puerto Rico stop on his 1942 world tour from One World. Willkie's widely debated vision revealed the conflicted state of American opinion about U.S. empire during the war.

This article presents an intellectual and social history of the concept of the baby boom. Researchers first invented the notion of a population bulge in the mid-twentieth-century United States to explain birth rates that were higher than predicted by their theories of a mature population and economy. As the children born during this “baby boom” entered schools in the 1950s, they were drawn into a pre-existing conversation about an educational emergency that confirmed researchers’ suspicions that the bulge would spread crisis over time throughout all of the nation's age-graded institutions. New sociological and demographic explanations of the bulge subsequently merged with heightened talk of generational conflict during the 1960s and 1970s to define, with journalistic help in 1980, the “baby boom generation” and the “baby boomer.” Crisis talk has pursued the boomers into the present, mobilized most effectively by opponents of the welfare state.

W. E. B. Du Bois stands as one of the most celebrated and studied African Americans in United States history. Nevertheless, Du Bois's substantial body of writings on World War I has received little scholarly attention. This article explores Du Bois's published and unpublished work, revealing the centrality of World War I to Du Bois's life and historical imagination. Du Bois devoted decades to writing about and grappling with the historical legacy of World War I for African Americans, broadly, and for himself, individually. His inability to find both collective and personal redemptive meaning in the war reflects his struggle to reconcile the tension between history and memory, as well as the still contested place of World War I in African American history.

In the 1950s, the top American Jewish organizations chose a single man, John Stone, to represent their collective interests in Hollywood. Over the course of the decade, Stone's Motion Picture Project sought to prevent antisemitism on film and to inspire the creation of positive Jewish characters. Negotiating the cultural politics of the era, however, resulted in an increasing tendency to favor depictions of biblical Jews over contemporary American ones. In a strange twist, Stone endorsed no film with as much zeal as Ben-Hur, a New Testament celebration of Jesus. By following Stone's tortuous attempts to navigate Cold War controversies, and by casting new light on the phenomenal success of biblical epics in the 1950s, this essay suggests that at the heart of postwar popular culture was a shift toward a particular discourse of liberal humanism.

This article examines the Amway Corporation, one of the largest direct sales companies in the world, and its founders, Republican kingmakers Richard DeVos and Jay Van Andel. It argues that Amway and its cofounders embodied small-business conservatism, an ideology that simultaneously critiqued government largesse and corporate capitalism, viewing both as threats to individual freedom. Beginning in the 1970s, DeVos and Van Andel became involved in the conservative effort to promote free enterprise and roll back government. At the same time, Amway and its allies presented direct sales as a more rewarding and liberating alternative to traditional, nine-to-five employment. This history highlights the important role that small-business conservatives played in the Right's campaign against the New Deal state between the 1930s and the 1980s.

The main components of the Israel lobby in the United States were organized in the spring of 1954, six years after the State of Israel declared independence, in response to a crisis in U.S.–Israel diplomacy that erupted in October 1953. Israeli soldiers had massacred more than sixty Palestinian villagers in Qibya, on the West Bank, eliciting widespread condemnation; American Jews, in reply, mobilized to defend Israel in new ways. The American Zionist Committee for Public Affairs (later renamed AIPAC) and the Conference of Presidents of Major American Jewish Organizations, established at this time, displayed two outstanding features. They were Jewish united front organizations that brought together Zionist with “non-Zionist” groups. They also emerged from transnational contacts with Israeli leaders and realities. A staunch near-consensus in defense of Israel in the most trying circumstances established a lasting framework in American Jewish life.

In the early 1970s, the African American divestment and boycott campaign against Gulf Oil's operations in colonial Angola bridged the gap between Black Power and anti-apartheid, two movements generally viewed separately. The success of the Boston-based activist couple Randall and Brenda Robinson in educating and mobilizing African Americans against investment in colonialism—first with the Southern Africa Relief Fund (SARF) and later with the Pan-African Liberation Committee (PALC)—reveals how a leftist anti-imperial ideology linked the domestic concerns of black Americans with African revolutions. At the same time, the Gulf campaign's participatory tactics, moral appeals, and critique of the global economic system proved attractive beyond radical Black Power advocates, allowing the PALC to cultivate relationships with African American politicians and build alliances across racial divides. Randall Robinson later replicated this organizing model as the founding director of TransAfrica, which became the most prominent African American organization opposing apartheid in the 1980s.

During the 1970s, activists first popularized the concept of “environmental justice” in the context of growing environmental degradation, racialized urban poverty, and working-class fears of plant closure. To address these problems, leaders in the United Auto Workers and other unions formed coalitions with civil rights and environmental groups, and advocated federal policies that would reduce both pollution and unemployment. This article argues that the defeat of these efforts, and the political marginalization of full employment and other social-democratic goals in the 1980s, resulted in a narrower conception of environmental justice among many scholars and activists. Revisiting this forgotten history calls into question common claims about environmentalism in recent scholarship on the 1970s, and suggests the need to revise conventional narratives of the emergence of the environmental justice movement.

Oil is the elephant in every room in modern American history. From the consumer-culture room to the politics room, the labor room to the U.S.-and-the-world room, oil is right there, as big as Texas, yet hardly anyone notices. That is less true than it used to be. The Journal of American History even devoted a special issue to oil in 2012. Yet modern American historians still have not thought enough about “crude reality.”
