Garage Door Opener Installation in San Juan Capistrano, CA

The region was populated by the Acjachemen, referred to by the Spanish as Juaneños, an Indigenous Californian nation. They lived in the area for approximately 10,000 years, with some of their oldest villages being confirmed as over 9,600 years old. The mother village of Putuidem was located in what is now San Juan Capistrano, as well as the village of Acjacheme.

San Juan Capistrano was established by the Spanish in 1776, when Saint Junípero Serra founded Mission San Juan Capistrano, the seventh of the Spanish missions in California. The mission was built less than 60 yards from the village of Acjacheme, which was exploited as a source of labor for the mission. The mission was named after St. John of Capistrano, a 14th-15th century Franciscan saint. The 1812 San Juan Capistrano earthquake resulted in the deaths of thirty-nine Acjachemen people, thirty-one of whom were women, when the stone church at the Mission collapsed.

The Mexican Congress of the Union enacted the secularization of the Californian missions in 1833. In the mission period, 4,317 natives had been baptized at the mission (1,689 adults and 2,628 children). In that same period, 3,158 of those baptized had died. Some of the native people who survived the mission period continued to live at the mission for a short period after the secularization act, while others settled in the surrounding areas.
