This study examines in detail the public career of Santos Degollado during the era of the Mexican Reforma, and, because of his central role in national events of that period, the story is presented in the context of a general history of the Reforma. Sources of information were largely primary, including manuscripts and newspapers from Mexican archives. The richest of these were the collection of Degollado's letters at the Instituto de Antropologia e Historia; manuscripts from the Secretaria de Relaciones Exteriores archive, the Archivo Juarez of the Biblioteca Nacional, and the Centro de Estudios de Historia de Mexico; as well as documents from various collections at the University of Texas Latin American Collection. Important published sources included the 36-volume collection edited by Genaro Garcia and the 15 volumes of Benito Juarez papers edited by Jorge L. Tamayo. In seeking to explain and justify aspects of Degollado's conduct and behavior which have heretofore often been characterized as aberrations, this study has suggested some revised interpretation of the role of Benito Juarez in the Reforma. This great Mexican hero of the nineteenth century has long overshadowed the other important figures of the period, including Degollado. This study contends that not only should other Mexicans receive a larger share of credit for the progressive advances made during the Reforma, but also that Juarez should receive less.
