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.
Fredonian Rebellion
After winning independence in 1821, several of Spain's colonies in the New World joined together to create a new country, Mexico. The country divided itself into several states, and the area known as Mexican Texas became part of the border state Coahuila y Tejas. To assist in governing the large area, the state created several departments; all of Texas was included in the Department of Béxar. The department was further subdivided into municipalities, which were each governed by an alcalde, similar to a modern-day mayor. A large portion of East Texas, ranging from the Sabine to the Trinity Rivers and from the Gulf Coast to the Red River, became part of the municipality of Nacogdoches. Most residents of the municipality were Spanish-speaking families who had occupied their land for generations. An increasing number were English-speaking residents who had immigrated illegally during the Mexican War of Independence. Many of the immigrants were adventurers who had arrived as part of various military filibustering groups, which had attempted to create independent republics within Texas during Spanish rule.
