In the years since the first edition of this important study was published, the changes in the Mexican American community in the United States have been great indeed. This extensively revised edition-with a new title-includes expanded chapters on these new developments of the recent past: the Chicano Movimiento of the late sixties and seventies; their considerable political and economic achievements; improvements in immigration law; the creative explosion in literature and the fine arts; the increased role of Chicanas; the rise and decline of four great leaders-César Chávez, "Corky" Gonzales, Reies López Tijerina, and José Angel Gutiérrez. An extensive account of the pre-Columbian world and the impact of the early Spanish explorers and settlers takes note of new findings and interpretations.
