The ECCA Project
The Early California Cultural Atlas (ECCA) is developing a digital atlas to integrate and manage historical resources and enable analysis of historical data related to the colonization and settlement of early California. The project is in the early stages of development. So far, several exploratory studies and interfaces have been constructed. Multiple types of data have been collected and integrated for two missions in the Monterey area and work is beginning for the Los Angeles area. Please read more: About the project
Early History of California - Demographic and land use changes from first encounter to California Statehood
Beginning in 1769, California was resettled by Spanish Franciscans, soldiers, and colonists. Over the next eighty years the peoples and lands of California were remade by political and biological forces that we are only now beginning to understand in their totality. The establishment of Mission San Diego in 1769 as the first of twenty-one Franciscan missions in California initiated the movement of tens of thousands of Indians to the missions where most died prematurely from disease. At that same time, Spanish livestock began to crowd out California’s native fauna, and introduced vegetation pushed aside indigenous plants, greatly undermining the subsistence practices of California Indians. During the 1830s and 1840s, the ownership of much of California passed from Indians to Spaniards and Mexicans, as Mexican governors granted large tracts of land to their followers, friends, and subordinates. The Early California Cultural Atlas (ECCA) attempts to demonstrate visually the spatial and temporal aspects of these enormous changes and thereby promote new ways of understanding California before 1850.
