White Americans became increasingly hostile and suspicious of Mexican Americans both during and after the Plan of San Diego raids. Small personal conflicts between Mexican Americans and white Americans led to the lynching and the execution of Mexicans by Texas Rangers, local officers and law enforcement, and civilians.[1] Local whites founded the vigilante Law and Order League in 1915, fueled by suspicions of Mexican and Tejano insurrection.[2] Federal officials estimated that from late 1915 to 1916, more than 300 Mexican Americans were slain in Texas.[5]
