This study establishes an intellectual profile of Albert Gallatin through his vision of government’s role in a democratic republic and the republic’s role in the community of nations. Only through a comprehensive analysis of Gallatin’s political and diplomatic activities can the student of history learn to see his actions as expressions of clearly formulated principles. Gallatin was much more involved in the shaping of administrative policy than has been recognized. Moreover, he followed his unique Gallatinian approach to domestic policy as well as international diplomacy, always in pursuit of one paramount objective: the preservation of individual liberty within the context of a republic.
