The purpose of the study was to compile an in-depth biography of Jonathan Jennings, the first state governor of Indiana. It was the first such research to originate on the central political figure in the development of Indiana statehood.All published or unpublished manuscript collections pertaining to Indiana politicians contemporary with Jennings were researched. Every Indiana state or territorial newspaper collection available during Jennings's years in government service were searched for references pertaining to his career. All federal, territorial or state public documents that could possibly refer to his career were studied. Fifty-three secondary books, fourteen journal articles, and seven published sets of reminiscences were utilized to complete this project.Findings1. Jonathan Jennings was a superb political organizer possessing a keen sense of timing and an ability to emotionalize political issues, to create personality clashes.2. Though generally Jeffersonian in outlook, Jennings was not an ideologue. He was a pragmatic politician, able to adapt his philosophy to the contingencies of the issues he supported.3. As a member of Congress, Jennings consistently voted from a provincial point of view.National issues, such as those which led the United States to the War of 1812, were viewed by Jennings as irritants which prevented Congress from legislating for the local needs of his constituents.4. Jennings's two terms as governor were his most valuable years of public service. His persistent support of state-financed public education, as well as aid to the elderly and infirm, indicated a sense of government responsibility uncommon for political leaders his day.5. Jennings was a frustrated, driven man who turned to alcohol rather than attempt to resolve deeply embedded feelings of inadequacy, a character flaw instrumental in his demise.Conclusions1. Rather than a prolific legislator in Congress, Jonathan Jennings was better characterized as an agitator, symbolizing the anti-Harrison, anti-slavery forces.2. Jennings's concern for local development enhanced his effectiveness as state governor. 3. Jennings's weakness for alcohol combined with the changing political structure produced by the emerging Jacksonian forces, brought to conclusion a political career which might otherwise have contributed for several years beyond its time. / Department of History
