"the book is a landmark treatment of Flores Magon. It provides new information regarding the importance of his early work with Mexican and Mexican-American labor and political issues....This study has far-reaching implications for Mexican as well as United States history." John M. Hart "MacLachlan’s study now points out that further inquiry needs to be done about the Magonista movement in Southern California with its unique followers. A two-story brick building in downtown Los Angeles was the headquarters for this radical crusade throughout the American Southwest and in parts of Mexico. The Magonistas in South Texas faithfully read the Los Angeles anarchist materials that arrived constantly in their region. In reading MacLachlan’s work, one quickly realizes that the Magonista drive was a complex political activity. His chapter "Arizona" reveals how in each state Magonismo effected every region along the Mexican border.[…]As a reference book, MacLachlan’s study is essential to understanding the Chicano experience during the first part of the twentieth century.
