However, the greater military power of the Europeans resulted in the indigenous people getting pushed further and further back from their native lands; this did not change when California became part of Mexico in 1821, despite the fact that the new government secularized the Spanish missions and as a result freed many enslaved indigenous people. Additionally, from 1820, El Camino Viejo a route between Los Angeles and San Francisco Bay along the west side the San Joaquin Valley began, which brought settlements into the valley. During Mexican rule, the mission lands in the San Joaquin Valley were subdivided to wealthy landowners ("rancheros") and caused even more conflicts between the Mexicans and the Native Americans. A famous leader of the natives was the Yokut Estanislao, who led revolts against the Mexicans in the late 1820s until finally defeated in 1829 on the Stanislaus River, which bears his name today.
