The 1822 Monterey Meeting: Alta California's Declaration of Independence

April 1822: A Pivotal Moment in Californian History

In April 1822, leaders of Alta California convened in Monterey to formally declare independence from Spain. This assembly marked the region's alignment with the newly established First Mexican Empire under Agustín de Iturbide.

Outcomes of the Meeting

• Political Realignment: Alta California transitioned from a Spanish colony to a territory of the Mexican Empire.
• Administrative Formation: The Alta California Territory was officially organized under Mexican governance.
• End of Spanish Rule: The meeting symbolized the practical end of over three centuries of Spanish colonial authority in the region.

Historical Context

Mexico had won its independence from Spain in 1821. News traveled slowly to the distant northern frontier. The Monterey meeting was the local manifestation of this sweeping change, setting the stage for the Mexican period in California (1822–1846), which preceded American annexation.
