For the Mexican government to go to war with its more powerful northern neighbor in 1846 was folly. Mexico surrendered to the United States more than half a million square miles of territory, contributing to a legacy of distrust and bitterness towards the U.S. that has never entirely dissipated. The real prize was California. The Californios--Spanish speaking, non-native inhabitants of the province of Alta (Upper) California--had ambiguous loyalties to the Mexican government and minimal military capabilities. American control of California was considered the keystone of Manifest Destiny, and naval and amphibious operations along the Pacific coast began as early as 1821 and continued for weeks after the end of the war. This book describes the often overlooked military and naval operations in California before and during the Mexican War, and introduces readers to the colorful Californios, the American adventurers who arrived after them, and the Indians, who preceded them both.

Antonio María Osio’s La Historia de Alta California was the first written history of upper California during the era of Mexican rule, and this is its first complete English translation. A Mexican-Californian, government official, and the landowner of Angel Island and Point Reyes, Osio writes colorfully of life in old Monterey, Los Angeles, and San Francisco, and gives a first-hand account of the political intrigues of the 1830s that led to the appointment of Juan Bautista Alvarado as governor. Osio wrote his History in 1851, conveying with immediacy and detail the years of the U.S.-Mexican War of 1846–1848 and the social upheaval that followed. As he witnesses California’s territorial transition from Mexico to the United States, he recalls with pride the achievements of Mexican California in earlier decades and writes critically of the onset of U.S. influence and imperialism. Unable to endure life as foreigners in their home of twenty-seven years, Osio and his family left Alta California for Mexico in 1852. Osio’s account predates by a quarter century the better-known reminiscences of Mariano Guadalupe Vallejo and Juan Bautista Alvarado and the memoirs of Californios dictated to Hubert Howe Bancroft’s staff in the 1870s. Editors Rose Marie Beebe and Robert M. Senkewicz have provided an accurate, complete translation of Osio’s original manuscript, and their helpful introduction and notes offer further details of Osio’s life and of society in Alta California.

""Decline of the Californios" is one of those rare works that first gained fame for its pathbreaking and original nature, but which now maintains its status as a classic of California and ethnic history."--Douglas Monroy, author of "Thrown among Strangers"

Presents an account of the Mexican War, providing an analysis of its cause, battles, weapons, and outcome.

Between 1846 and 1873, California’s Indian population plunged from perhaps 150,000 to 30,000. Benjamin Madley is the first historian to uncover the full extent of the slaughter, the involvement of state and federal officials, the taxpayer dollars that supported the violence, indigenous resistance, who did the killing, and why the killings ended. This deeply researched book is a comprehensive and chilling history of an American genocide. Madley describes pre-contact California and precursors to the genocide before explaining how the Gold Rush stirred vigilante violence against California Indians. He narrates the rise of a state-sanctioned killing machine and the broad societal, judicial, and political support for genocide. Many participated: vigilantes, volunteer state militiamen, U.S. Army soldiers, U.S. congressmen, California governors, and others. The state and federal governments spent at least $1,700,000 on campaigns against California Indians. Besides evaluating government officials’ culpability, Madley considers why the slaughter constituted genocide and how other possible genocides within and beyond the Americas might be investigated using the methods presented in this groundbreaking book.

The Mexican-American War of the 1840s, precipitated by border disputes and the U.S. annexation of Texas, ended with the military occupation of Mexico City by General Winfield Scott. In the subsequent treaty, the United States gained territory that would become California, Nevada, New Mexico, Arizona, Utah, and parts of Wyoming and Colorado. In this highly readable account, John S. D. Eisenhower provides a comprehensive survey of this frequently overlooked war. NOTE: This edition does not include photographs.

Celebrating the 150th birthday of the state of California offers the opportunity to reexamine the founding of modern California, from the earliest days through the Gold Rush and up to 1870. In this four-volume series, published in association with the California Historical Society, leading scholars offer a contemporary perspective on such issues as the evolution of a distinctive California culture, the interaction between people and the natural environment, the ways in which California's development affected the United States and the world, and the legacy of cultural and ethnic diversity in the state. California before the Gold Rush, the first California Sesquicentennial volume, combines topics of interest to scholars and general readers alike. The essays investigate traditional historical subjects and also explore such areas as environmental science, women's history, and Indian history. Authored by distinguished scholars in their respective fields, each essay contains excellent summary bibliographies of leading works on pertinent topics. This volume also features an extraordinary full-color photographic essay on the artistic record of the conquest of California by Europeans, as well as over seventy black-and-white photographs, some never before published.
