From 1924 to 1929 the Roman Catholic Church and the Mexican State engaged in the crucial stage of a long-time struggle to determine whether the former would be independent of or subordinate to the latter. This thesis analyzes Church-State relations during this five year period and stresses the activities of President Plutarco Elías Calles, the Roman Catholic hierarchy, and more fanatic Mexican Catholics.

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.

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.
