This paper provides a thematic approach to three major United States government document series relating to topics of early United States diplomatic relations with Mexico; treaty negotiations, the Santa 'Fe trade, the Texas question, and claims. The document series examined are .the United States presidential papers, United States Congressional documents , and the National Archives Record Group 59, diplomatic dispatches from United State Ministers to Mexico. Historians must make an evaluation of all: documentary evidence available for an accurate assessment of historical events. Inadequate analysis of these major United States document series has limited this necessary assessment in the area of United States Mexican diplomatic relations, 1821-1846.

This thesis presents a history of the United States' war with Mexico with a focus on the maturing of the United States artillery on the battlefields of Mexico.

This study analyzes the procedures and operations of the Quartermaster, Ordnance, Commissary, and Medical Departments during Scott's campaign to determine the efficiency of the prevailing logistical system. Unpublished and published government documents, official records, manuscript collections, memoirs, diaries, and newspapers provide the data. The first chapter describes the logistical departments interworkings; the remaining chapters detail the operations of the bureaus during the expedition's assembly and campaign against Mexico City. The evidence revealed organizational deficiencies which caused severe shortages, particularly in transportation, for Scott's army. The shortages severely hampered the expedition. Because of .the numerous victories over 'Mexican forces, however,. American leaders ignored the organizational deficiencies, These shortcomings reappeared to .impede operations during the Civil War.

This study examines the efforts of the Union and Confederate diplomatic agents to influence the events along the Rio Grande during the Civil War. The paper compares the successful accomplishments of Confederate agent Jose Quintero to the hindered maneuverings of the Union representatives, Leonard Pierce and M. M. Kimuey. Utilizing microfilmed sources from State Department records and Confederate despatches, the paper relates the steps Quintero took to secure the Confederate-Mexico border trade, obtain favorable responses from the various ruling parties in northern Mexico, and hamper the Union agents' attempts to quell the border trade.

The Revolution of 1910 in Mexico marked a great political and social upheaval. At the same time a recasting of Mexico's music occurred. Modern Mexican music is a unique combination of the influence inherited from Europe and the indigenous music of the country. This work attempts to trace the development of that combination. Chapter I gives a background of music in Mexico through Pre-Cortesian times, the colonial period and the operatic nineteenth century. Chapter II deals with the men who shaped present day music in Mexico. Chapter III is an analysis of selected twentieth century piano works. The analysis shows the tendencies of ten Mexican composers in their use of melody and rhythm. It includes a discussion of harmonic structure and tonality. The composers whose works were chosen for consideration in the analysis range from Manuel M. Ponce, considered the father of modern Mexican music, to Carlos Chavez, recognized as the outstanding exponent of music in Mexico today.

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.

This thesis examines newspapers and correspondence of public men in the era of the Mexican war to provide some answers to pertinent questions regarding the South's role in the Mexican War. It attempts to reveal to some degree whether Southerners uniformly supported the war, whether their support arose from an expansionist sentiment or a desire to extend the area of slavery, whether any strong opposition to the war existed in the South, and why they supported or opposed it.

This thesis contributes analyses of two works by Mexican composers: Rayo nocturnal (1989) by Victor Rasgado (b. 1959), and the Cuarteto da do (1988) by Juan Trigos (b. 1965). Although composed according to structuralist principles, a postmodern interpretation is offered. The analytical method applied is based on Allen Forte's set theory, including rhythmic and timbral dimensions that are integral to the conceptions of these works. A survey of modernism and postmodernism in twentieth-century Mexico serves to place these works in their cultural context.
