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.
Celebration of Mexican political anniversaries in 2010
The two dates represent the beginning of the Mexican War of Independence and Mexican Revolution respectively. The anniversary of the War of Independence is called "El Grito" (The Shout or The Cry) and takes place at 11 pm on 15 September, with the following day 16 September officially marking Mexico's Independence. El Grito is a re-enactment of the call made by Miguel Hidalgo y Costilla in Dolores Hidalgo, Guanajuato at around 6 am on 16 September 1810 to his parish to take up arms against the Spanish colonial government. Each year, this re-enactment occurs not only on the main square (Zócalo) of the capital, Mexico City, but also on every main plaza in almost all communities in the country.
