In late 1776 Mission San Juan Capistrano was established amid Acjachemen (Juaneño) tribal territory by the Franciscan religious order and the Spanish army. But by Spring 1778, the Acjachemen were planning an uprising. While the uprising was ultimately unsuccessful, military reports surrounding the incident – including the interrogation of its leaders — shed a great deal of light on the Acjachemen’s cultural motivations for warfare, on their view of Spanish aggression toward their people, and on the consensus-building process among clans necessary for such a major undertaking. When studied in concert with demographic data from the mission register, these records also tell us more about local villages and their chiefs. Studying this event provides us with a better understanding of the Acjachemen response to the Euro-Christian attack on their traditional culture, including both active defense and withdrawal.
