This chronological anthology consists of documents and articles on the history of Mexican American people in the 20th century. The anthology may be directed to students in higher education, historians, and those interested in the Mexican American people. Section I spans the period from 1900 to 1920 and introduces immigration as the starting point for the history of La Raza in this century. Section II, covering from 1920 to 1930, describes the movement of Mexicans and Mexican Americans from their Southwest heartland to steel mills, packing plants, and "colonias" of the Midwest. Other sections address themselves to the development of a hostile attitude on the part of many Americans to the rising tide of Mexican immigration, as was exemplified by the Harris and Box bills in Congress. Section III deals with repatriation in the 1930's. Chicano World War II experiences both at home and overseas are described in Section IV. The Second World War introduced a new era in Mexico-United States relations, formalizing the use of bracero labor. Section V traces continuing postwar demands for Mexican labor and the resultant increase in both braceros and majados. The impact of these workers eventually led to "Operation Wetback" and finally to termination of the bracero program in 1964. Section VI encompasses a broad spectrum of contemporary Chicano activities and ideology, especially an increased and more aggressive political activity. These 6 sections are chronologically sequential, with some unavoidable overlap. (FF)
