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.
