A Complex History

Indigenous and Colonial Eras

Before European arrival, California was home to a vast array of Indigenous tribes with diverse languages and cultures.

European contact began in earnest in 1542 when Portuguese explorer Juan Rodríguez Cabrillo claimed the region for the Spanish Empire. This paved the way for the Spanish period, characterized by the establishment of missions, such as Mission San Juan Capistrano in 1776, intended to spread Catholicism and secure Spanish control.

From Mexico to American Statehood

Following Mexican independence, California became a Mexican territory. However, the 1830s and 40s saw rising tensions and movements for independence, including the 1836 movement led by Juan Bautista Alvarado.

The 1846 Bear Flag Revolt declared the California Republic, which served as a precursor to the American conquest. The conflict ended with the Treaty of Cahuenga in 1847, a ceasefire signed by Andrés Pico and John C. Frémont.

The California Genocide and Modern Era

The transition to American rule was marked by a dark period known as the California genocide. Between 1846 and 1873, government agents and private settlers perpetrated massacres against Indigenous Californians, with death estimates ranging from 9,456 to 100,000.

The 20th century brought transformative events, including the devastating 1906 San Francisco earthquake and the rise of the entertainment industry in Hollywood, which solidified Los Angeles as a global economic hub.
