This PowerPoint presentation deals with the creation and ratification of the U.S. Constitution. It begins with a brief examination of the 55 delegates who gathered in Philadelphia in 1787 and their motivations. It then deals with the "bundle of compromises" that they created including the Great Compromise (Connecticut Compromise) the compromise over commerce, the creation of the Electoral College and the Three-Fifths Compromise. It goes on to look at the ways in which the power of the federal government was expanded including the Supremacy Clause and the Necessary and Proper Clause (Elastic Clause). It briefly touches on the system of checks and balances before it delves into the ratification process. The specific arguments made by the Federalists and Anti-Federalists are covered. It concludes with an examination of the argument made by James Madison in the Federalist No. 10. This PowerPoint is used in an A.P. United States history class and is based, in part, on Chapter 9 of The American Pageant, 14th ed.
