Presented by Willard Hurst as part of his course "Introduction to Modern American Legal History" at the University of Wisconsin Law School in 1978. This lecture serves as a continuation of the previous discussion on conflicts of interests, but narrows in on lobbying and special interest groups. Madison's Federalist Number Ten essay is investigated for its ideas on social and political peace, and this leads into a consideration of social peace and the inherent nature of power. The presence of power and conflicts of interests are found within the examples of the Whiskey Rebellion, the 1824 case of Gibbons v. Ogden, and the way the Marshall court handled the commerce clause. The expansion of the federal government's powers are examined and presented as mainly positive and facilitative acts. This begins with a consideration of the effects of John Marshall's handling of interstate commerce, federal taxation to raise revenue, the 1830 protective tariff, and subsidies awarded to the private market. The element of competitive bargain and selfish interests are also examined through Henry Clay's ideas on national use of the economy, and Calhoun's desire to protect southern power.
