This clip from Latino Americans focuses on Mariano Guadalupe Vallejo. Vallejo was an elite californio who experienced the transformation of California from the northern outpost of Mexico to the burgeoning western frontier of the United States. Though he was made a prisoner during the Bear Flag revolt, he would embrace his new nation. Land grabs and even lynchings were common in the Gold Rush era. In order to protect his property and rights, Vallejo would eventually take his case all the way to the Supreme Court.
