This study is concerned with the struggle between the Roman Catholic Church and the Mexican government following the Revolution of 1910 to 1920. The purpose is to investigate and evaluate both the role of the Church in the politics, economy, and society of Mexico in the post-Revolutionary era and the efforts of the liberal governments of Alvaro Obregón, Plutarco Calles, and others to diminish that role.

This thesis examines the imagery of Jose Guadalupe Posada in the context of the Mexican Revolution with particular reference to the corrido as a major manifestation of Mexican culture. Particular emphasis is given to three corridos: "La Cucaracha," "La Valentina," and "La Adelita." An investigation of Posada's background, style, and technique places him in the tradition of Mexican art. Using examples of works by Posada which illustrate Mexico's history, culture, and politics, this thesis puts Posada into the climate of the Porfiriato and Revolutionary Mexico. After a brief introduction to the corrido, a stylistic analysis of each image, research into the background of the song and subject matter, and comments on the music draw together the concepts of image, music, and text.

The purpose of this study is to examine the role of Santos Degollado in the history of Mexico during the 1850's and to determine his contributions to the cause of constitutional reform in that period.
