The Latino Big Bang in California presents a Spanish transcription and English translation of a diary written by Forty-Niner Justo Veytia, a Mexican immigrant seeking riches during California's Gold Rush. Veytia's diary offers insights into the dilemmas and choices of an adventurous and ambitious young mexicano and provides a detailed glimpse into the life of Latinos who participated in this tumultuous moment in California history. In doing so, Veytia's diary demonstrates that the US-Mexico War together with the Gold Rush constituted a Latino "big bang" in California that attracted large swaths of fortune seekers from across the Spanish-speaking world throughout the latter half of the nineteenth century. Combining archival research with quantitative methods to extrapolate demographic information about the persistent presence of Latino communities in California from the mid-nineteenth century to today, The Latino Big Bang in California shows how Latino migration and labor forever changed the course of California history.

During 1873 a jury trial took place in San Diego to decide whether Pio Pico, the last Mexican governor of California, had been the victim of a fraud by his brother-in-law, John Forster.Pico claimed title to the huge Rancho Santa Margarita y Las Flores land grant in southern California, located approximately 208 square miles north of San Diego on the California coastline, and today occupied by Camp Pendleton. Pico's battle to retain that grant in the face of formidable legal challenges from John Forster and others, provides an absorbing view of California during its transitional era and Americanization. The introductory chapters are a sweeping view of early California history with an account of the important roles the Pico family and John Forster played in it. Based on meticulous research, including many records, letters, and photographs never before published, the intimate lives and foibles of some of California's most colorful historical figures are examined in unprecedented detail. After a full description of the trial, a definitive analysis of the evidence is given which proves that the controversial verdict should have been different. The underlying circumstances and motives of the struggle between Forster and Pico are fully explained.
