Contra Costa County, California
In 1821 Mexico gained independence from Spain. While little changed in ranchero life, the Mexican War of Independence resulted in the secularization of the missions with the re-distribution of their lands, and a new system of land grants under the Mexican Federal Law of 1824. Mission lands extended throughout the Bay Area, including portions of Contra Costa County. Between 1836 and 1846, during the era when California was a province of independent Mexico, the following 15 land grants were made in Contra Costa County.

It was through the means of armed combat that Mexico achieved its independence from Spain. From then on, the course of history was marked by several armed conflicts, including the American (1846–48) and French (1861–67) conflicts, as well as indigenous struggles due to the several forms of government that ruled over Mexican territory, culminating with the Mexican Revolution (1910–20) and the Cristero War (1926–29).
