Hal Brands argues that a better understanding of Eurasia's strategic geography can illuminate the contours of rivalry and conflict in today's world. The Eurasian Century explains how revolutions in technology and warfare, and the rise of toxic ideologies of conquest, made Eurasia the center of twentieth-century geopolitics—with pressing implications for the struggles that will define the twenty-first.

Fight for the Final Frontier uses the concepts associated with irregular warfare to offer new insights for understanding the nature of strategic competition in space. Today's most pressing security concerns are best considered using an irregular warfare lens because incidents and points of potential conflict fall outside the definition of armed conflict.

In 2016, the United States was stunned by evidence of Russian meddling in the US presidential elections. But it shouldn't have been. Subversion—domestic interference to undermine or manipulate a rival—is as old as statecraft itself. The basic idea would have been familiar to Sun Tzu, Thucydides, Elizabeth I, or Bismarck. It came as a surprise in 2016 because the sole superpower had fallen asleep at the wheel. But what's really new? Have we entered a new age of vulnerability?

At the dawn of the twentieth century, José Cuervo inherited his family's humble distillery, La Rojeña, in the Tequila Valley. Within a decade, it would become Mexico's leading producer of tequila. But when the Mexican Revolution erupted, a charge of treason and a death threat against him by Pancho Villa forced Cuervo to flee. In Tequila Wars, award-winning author Ted Genoways restores Cuervo to his place as a key player in Mexico's formative period. Before the revolution, Cuervo's acclaim spread worldwide, and once war broke out, Cuervo remained an impresario, kingmaker, and cultural force.

Although the fundamental nature of war has not altered over the centuries, constant change, innovation, and adaptation have repeatedly reshaped how wars are fought in the West.

In this epic narrative, Frederic Raphael explores the most significant moments, ideas and figures that have shaped the world’s stage. He takes us on a journey through history: from the reigns of Julius Caesar and Alexander the Great, to Plato and Socrates and the origins of philosophy, the turning point of World War Two and the invention of the atom bomb, and, finally, the social and cultural divisions of modern day. It is often a story of conflict: the rise of anti-Semitism, the tensions between science and faith, progress and strife, comedy and ruthlessness.

Marcus Rediker, one of the leading scholars of maritime history, puts his command of archival research on full display in this luminous portrait of the Atlantic waterfront as a place of conspiracy, mutiny, and liberation.

In 1898, on the eve of the Spanish-American War, the US Army seemed minuscule and ill-equipped for global conflict. Yet over the next fifteen years, its soldiers defeated Spain and pacified nationalist insurgencies in both Cuba and the Philippines.

After the Supreme Court ruled in 2023 that the use of race in college admissions was unconstitutional, many predicted that the black middle class was doomed. One byproduct of a half century of affirmative action is that it has given people the impression that blacks can’t advance without special treatment. In The Affirmative Action Myth, Jason L. Riley details the neglected history of black achievement without government intervention. Using empirical data, Riley shows how black families lifted themselves out of poverty prior to the racial preference policies of the 1960s and 1970s.
