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.
Name of Mexico
In September 1821, the independence of Mexico was finally recognized by Spain, achieved through an alliance of royalist and revolutionary forces. The former tried to preserve the "status quo" of the vice-royalty, menaced by the liberal reforms taking place in Spain, through the establishment of an autonomous constitutional monarchy under an independence hero. Agustín was crowned and given the titles of: Agustin de Iturbide por la divina providencia y por el Congreso de la Nación, primer Emperador Constitucional de Mexico (Agustín de Iurbide First Constitutional Emperor of Mexico by Divine Providence and by the Congress of the Nation). The name chosen for the country was "Imperio Mexicano", "Mexican Empire". The empire collapsed in 1823, and the republican forces drafted a constitution the following year whereby a federal form of government was instituted. In the 1824 constitution, which gave rise to the Mexican federation, "Estados Unidos Mexicanos" (also "Estados-unidos mexicanos")—literally the "Mexican United States" or "Mexican United-States" (official English translation: "United Mexican States")—was adopted as the country's official name. The constitution of 1857 used the term "República Mexicana" ("Mexican Republic") interchangeably with "Estados Unidos Mexicanos"; the current constitution, promulgated in 1917, only uses the latter and "United Mexican States" is the normative English translation. The name "Mexican Empire" was briefly revived from 1863 to 1867 by the conservative government that instituted a constitutional monarchy for a second time under Maximilian of Habsburg.
