It is funny how the action of one person affects the history of mankind, or in this case for America. The infamous Battle of the Alamo of 1836 brought forth the ultimate conquest of California and nine other nearby states. In the Battle of the Alamo, Texans who claimed their loyalty to the United States died trying to protect the land that they found, but ended up being massacred by the Mexican army outnumbered. News of this battle eventually reached the citizens of the United States, causing a new form of patronization and a sense of unification once felt during the American Revolution. The Mexican Army surrended, and the Mexican War had ended peacefully (source).
Through the Treaty of Guadalupe Hidalgo, the United States gained control over California, Nevada, Utah, Arizona, Kansas, Colorado, Wyoming, Oklahoma, New Mexico, and Texas.
