These letters were later collected and reprinted as The Federalist. He became secretary of the Treasury under Washington in 1789. Disputes with Madison andJefferson in the early 1790s led to the development of the Federalist Party which he led at a critical period in American political history. As first secretary of the Treasury Hamilton attempted to put the United States on a sound financial footing especially since debt was consuming more than 50 percent of annual government revenues. He had a plan as did a successor Albert Gallatin to totally extricate the country from debt within 15 years but the Louisiana Purchase would intervene. Hamilton s main contributions to business were twofold. As Treasury secretary he favored establishing a national bank and also opposed excessive government spending. He also supported businessmen whom he believed were the lifeblood of the nation. His essay The Report On Manufactures 1791 strongly supported early forms of manufacturing as a way of developing a strong economy less dependent upon agriculture and imports of finished goods from Britain.
