Security Guard in Duarte, CA

Around 500 B.C., a band of Shoshonean-speaking Indians established settlements in what is now the San Gabriel Valley. These Native Americans came to be called the Gabrieliño Indians (after San Gabriel, the local mission) by early Spanish explorers, but now prefer to be called the Tongva. The Tongva did not practice agriculture, but instead relied upon the wild seeds, berries, and plants that grew near the rivers and marshlands. Since the San Gabriel Valley area was home to large numbers of oak trees such as coast live oak and interior live oak, a staple of the Tongva diet was an acorn mush made by boiling acorn flour.

Duarte’s history with Europeans dates back to 1769, when all land in California was claimed by the king of Spain. The first Europeans visited the San Gabriel Valley, including Duarte, during a 1769 expedition from San Diego to Monterey Bay commanded by Don Gaspar de Portolà. Accompanying Portolà was a Franciscan priest from Junípero Serra’s order in Mexico, Juan Crespí, who served as the diarist of the expedition. Much of what is known of early California is known only from the detailed descriptions recorded by Crespi.

On September 8, 1771, the Franciscans established the Mission San Gabriel Arcangel in the San Gabriel Valley. The mission was a resting point for early California travelers and gathered most of the native Tongva into an agricultural lifestyle. Following Mexican independence in 1821, the mission lands were nationalized.
