Several books have been written about Sam Rayburn, but thus far there has been no attempt to analyze Rayburn's rise to power. No one has delved sufficiently into his political philosophy, his motivations, and his personal convictions regarding the pivotal events of the turbulent 1930s. This dissertation endeavors to fill that void by tracing the course of events which led Sam Rayburn to the speakership of the United States House of Representatives. It records his triumphs, his shortcomings, the concessions he made, and the people he served in order to achieve his life's ambition. The scope of this study ranges from Rayburn's first expression of interest in the speakership to his elevation to that position in 1940. Brief coverage is given to his three terms in the Texas Legislature, beginning in 1906, and his election to Congress in 1912. A more extensive analysis is made of his early congressional association with John Nance Garner and its pivotal influence on his career. A brief analysis is offered of Rayburn's political and legislative activities prior to the election of 1932. The primary emphasis of this study, however, revolves around Rayburn's activities during the years 1932-1940-- the first two terms of President Franklin D. Roosevelt, and the period in which Sam Rayburn completed his methodical odyssey to the speakership.
