Dual federalism was used in the U.S. under Jacksonian democracy (Andrew Jackson), emphasizing local autonomy and individual liberty. After the Civil War, the federal government increased power and moved away from dual federalism. Key Terms laissez-faire: an economic environment in which transactions between private parties are free from tariffs, government subsidies, and enforced monopolies with only enough government regulations sufficient to protect property rights against theft and aggression.
Expansion of Federal Power During the Civil War. Professor ERIC FONER (Columbia University): The Civil War expanded federal power in enormous ways. The financing was one. You never had a national currency before the Civil War. Now you had it. The federal taxation system was miniscule. Before the Civil War, basically, the tariff paid for the federal government. Now you had taxes on everything, which means a whole Internal Revenue Service, which means tax collectors, revenue officers. And in many, many other ways: the first draft in American history is during the Civil War. The federal government intervenes, you might say, into the lives of individual citizens in ways that were unprecedented, in order to mobilize resources to fight the war.
