This study is an examination of the contributions made by George A. Smith (1817-1875) to the Mormon society in the Utah Territory. It is an historical exposition and appraisal of his work as a Church leader, colonizer, historian, military leader, and politician.George A. Smith was one of the most distinguished Mormon leaders during Brigham Young's administration as Church President. He played a vital role in aiding the exiled saints living in Iowa to complete the long exodus to Utah. The first colonizing mission to venture south of Utah Valley was led by George A. Smith. He acted as an administrative overseer to the central and southern Utah communities during most of his career in the territory. He assisted in the establishment of new communities in the region and concerned himself with their spiritual well-being as a Church leader, their political and economic growth as a legislator and economist, and their protection as a military leader. The study concludes that probably no man, save Brigham Young himself, made greater contributions as a Mormon colonizer and community builder. It is also maintained in the dissertation, that George A. Smith's achievements as a Mormon historian apparently exceeded that of any other nineteenth century Church member.

The purpose of this study is to analyze the influence exerted upon the people of the "Iron Mission" by George A. Smith through the spoken word, and to determine if the influence thus exerted played a major part in the success or failure of the mission.
