History

Early Years

The diocese was created amid growing Catholic communities in the mission territories of Alta and Baja California following Mexican independence. Bishop Francisco Garcia Diego y Moreno, appointed as the first and only residential ordinary, focused on restoring mission properties and establishing new parishes.

Suppression

The see was suppressed in 1849 following the Mexican-American War and the cession of Alta California to the United States. Its territory was reorganized, with the northern portion becoming the Diocese of Monterey.

Geography

The diocese covered the historical regions of Alta California and Baja California, corresponding to modern-day California in the United States and the Baja California peninsula in Mexico. It formed part of the broader ecclesiastical structure in northern Mexico during the early nineteenth century.

Mother Church

The Cathedral of Our Lady of Guadalupe in San Diego served as the mother church until the see's reorganization.

Fun facts

Below are some fun facts about the Diocese of Both Californias:

Did you know? The Diocese of Both Californias was the very first Catholic diocese established specifically for the Californias, created by Pope Gregory XVI in 1840 to bring order to the old Spanish missions after Mexican independence!

Surprise! Its only residential bishop, Franciscan friar Francisco Garcia Diego y Moreno, traveled extensively on horseback to visit far-flung missions across both Alta and Baja California.

Here's something cool: The diocese existed during the dramatic shift from Mexican rule to American control after the 1848 Treaty of Guadalupe Hidalgo, making it a bridge between two eras of California history.

Wow moment: The mother church was the Cathedral of Our Lady of Guadalupe in San Diego, one of the earliest permanent Catholic centers in the region.

Little-known gem: After just nine years the diocese was divided, giving rise to the modern Diocese of Monterey and eventually the Archdiocese of Los Angeles.
