American Economic History, Part II examines how markets, political power, and financial institutions shaped the United States from the sectional crisis through the Depression of 1920–21. The course begins with slavery, tariffs, banking privileges, wartime mobilization, Republican political economy, and the economic consequences of the War Between the States. It then follows the National Banking System through monetary expansion, international capital flows, recurring panics, liquidation, and the campaign that culminated in the Federal Reserve. A broader study of industrial society considers fiscal policy, regulation, labor and migration, land use, capital accumulation, technological change, and rising standards of living. The final lessons show how the First World War expanded federal control over production, labor, finance, taxation, and debt, before tracing the inflation, contraction, fiscal retrenchment, and recovery surrounding the Depression of 1920–21.
