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.
Cry of Dolores
The Cry of Dolores has assumed an almost mythical status. Since the late 20th century, the event has come to symbolize Mexican independence and to initiate Independence Day ceremonies the following day (16 September). Independence Day in Mexico is a patriotic holiday, marked by parades, concerts, patriotic programs, drum and bugle and marching band competitions, and special programs on the national and local media outlets.
