“Year of meteors! brooding year!” wrote Walt Whitman about the year 1860. New York City was a tinderbox. As the country’s trading capital, the city was caught in an unholy alliance with slave-owning cotton planters. Southern sympathizers—the mayor among them—shared the streets with abolitionists like Henry Ward Beecher. Abraham Lincoln began his unlikely march to the presidency in a speech at Cooper Union, and torch-bearing militiamen marched for him while merchants and secessionists organized against him. The city was a place of parades, séances, human trafficking and slavecatching, quack cures, dire poverty, and political fervor, hopelessly riven by the looming presidential election.
This book is a biography of New York City in the year before the Civil War, from the moment the telegraph brought news of John Brown’s raid on Harper’s Ferry in October 1859 to the first shots on Fort Sumter in the spring of 1861. Joshua K. Leon tells this story month by month through the eyes of those who lived it, weaving together the intersecting lives of the giants of the age, forgotten celebrities, and the everyday people in the city’s swelling crowds: the obsessive diarist George Templeton Strong, the “Queen of Bohemia” Ada Clare, the journalist Thomas Butler Gunn as he goes undercover in the secessionist South, the showman P. T. Barnum and his American Museum in downtown Manhattan, the frustrated actor John Wilkes Booth, and many more. New York, 1860 recovers lives led in the shadow of catastrophe, capturing the dreams, romances, laughter, and fears of New Yorkers as history bore down on them. In vivid detail, this book brings their city to life in all its filth and glory.
He spoke on project, midway through researching it, for New York Historical.

Joshua K. Leon’s most recent book is called World Cities in History: Urban Networks From Ancient Mesopotamia to the Dutch Empire, from Cambridge University Press. It has been called “the definitive worldwide analysis of pre-industrial cities.” World Cities in History explores 6,000 years of urban networks and the politics that drove them, from Uruk in the fourth millennium BCE to Amsterdam’s seventeenth-century ‘golden age.’ It provides a fresh, interdisciplinary reading of significant periods in history, showing how global networks have shaped everyday life. Alongside grand architecture, art and literature, these extraordinary places also innovated ways to exert control over far-flung hinterlands, the labor of their citizens, and rigid class, race and gender divides. Asking what it meant for ordinary people to live in Athens, Rome, Chang’an, or Baghdad – those who built and fed these cities, not just their rulers – he offers one of the few fully rendered applications of world cities theory to historical cases. The result is not only vividly detailed and accessible, but an intriguing and theoretically original contribution to urban history. As one critic pointed out, the book is an “invigorating comparative grand tour of ‘world cities’ over the past five thousand years which is sure to spark much debate.” See synopsis here.
New review:
“The strength of this volume, authored by political scientist Joshua K. Leon, lies in its use of ten selected case studies to illustrate the diverse preconditions and primary factors that drove the rise of specific cities—or urban networks—and to highlight several intriguing phenomena.”
-Sven Günther, Historische Zeitschrift.
His first book, The Rise of Global Health: The Evolution of Effective Collective Action, was released in 2015, with a paperback release in 2016. The book analyzes how major actors such as the World Health Organization and World Bank fostered an expanded global health regime, aggressively addressing the health related aspects of globalization.
