It was the purpose of this study to bring together for the first time the story of how the Democratic Convention of 1928 was brought to Houston; how that convention, including the events leading up to it, took place; and how those events and the subsequent issues raised, were reflected in the platform of the party. The actions described are important both as a local event, in Houston, and as a national event. Some writers have been inclined to interpret these events of 1928 as a test of religious toleration in the United States, but the facts refute this interpretation. Although it is true that there was more than one issue involved in the convention and the subsequent campaign and election, the dominant factor was a question of prohibition, not a question of religion. The history of the development of the question of prohibition and its injection into the convention of 1928 is traced in chapter II. Chapter I relates the events that led to choosing Houston as the convention site, and the events that took place in Houston when it was learned that this city had been chosen. Chapter II traces the efforts of the various leading candidates within the party as they struggled for control of the votes that would make them the nominees of the party. Chapter III relates the happenings of the convention, and Chapter IV concludes the thesis with a discussion of the platform adopted by the convention, of the issues involved at the convention, and of the effect of the convention on Houston. Throughout the thesis short political biographies of the leading candidates are included to give the reader an idea of the importance of these persons and their places in the party. Appendix A gives a short history of the site of the Sam Houston Hall, and Appendix B gives an accounting of the voting, person by person, for the city in which the convention would be held.
