Although most Americans view Sam Houston as a military leader and practical politician with little understanding of intellectual issues, he actually possessed a complex moral and political philosophy which he elaborated and demonstrated during a fifty-year public career. He based his philosophy on a mixture of Christian idealism and pragmatic realism, with duty, honor, and strict morality serving to restrain his love of reality, reason, and physical pleasures. The dual nature of his moral beliefs extended into his politics, which mixed Jeffersonian republicanism, individual rights, and limited government, with Jacksonian democracy, the needs of society, and the will of the people. Throughout most of his career he kept those conflicting sets of ideals successfully in balance, with only the turmoil of the 1850s leading him into extreme positions.

This thesis examines the letters, proclamations, and addresses of the four presidents of the Republic of Texas, David G. Burnet, Sam Houston, Mirabeau B. Lamar, and Anson Jones, to determine how these men faced the major crises of Texas and shaped policy regarding land, relations with Native Americans, finances, internal improvements, annexation by the United States, and foreign relations. Research materials include manuscript and published speeches and letters, diaries, and secondary materials.
