Governor Alvarado granted Rancho San Antonio to Juan Prado Mesa in 1839. The chief commercial products of the ranchos were cattle hides and tallow. After 1833, land grants were mainly given to army veterans and many ranchos were established. In 1822, Mexico became independent and the Secularization Act stripped the missions of their holdings. Mission Santa Clara de Asis was founded in October of the same year. An expedition led by Colonel Juan Baptista de Anza passed through this area in March of 1776.

A large village, known as Partacsi, was located in this general area. The Ohlone Indians lived in the Rancho San Antonio area for over 3,000 years prior to the arrival of the Europeans.
