The Mexican Revolution probably affected Texas more than any other state. As the Revolution intensified, Texans responded with increased efforts to shape the Mexican policies of the Woodrow Wilson administration. Some became directly involved in the Revolution and the U.S. reaction to it, but most Texans sought to influence American policy toward Mexico through pressure on their political leaders in Austin and Washington. Based primarily on research in the private and public papers of leading state and national political figures, archival sources such as the Congressional Record and the Department of State's decimal file, major newspapers of the era, and respected works, this study details the successes and failures that Texans experienced in their endeavors to influence Wilson's Mexican policies.

The Comanche Indians presented a major challenge to the Republic of Texas throughout its nine-year history. The presence of the Comanches greatly slowed the westward advancement of the Texas frontier, just as it had hindered the advancing frontiers of the Spaniards and Mexicans who colonized Texas before the creation of the Republic. The Indian policy of the Republic of Texas was inconsistent. Changes in leadership brought drastic alterations in the policy pursued toward the Comanche nation. The author examines the Indian policy of the Republic, how the Comanches responded to that policy, and the impact of Texan-Comanche relations on both parties.
