American political ideology forms the strong basis of American Dream. The key dominating ideology that is ingrained into American politics is placed on the concept of Republicanism and classical liberalism. Documents that showcase the strong American political ideology are: Declaration of Independence (1776), Constitution(1787), The Federalist Papers (1788), Bill of Rights (1791), and Abraham Lincolnā€˜s Gettysburg Address (1863) respectively. There are many others in the list though! Laissez-faire ideology was quickly dumped in the 1930s at the time of Great Depression.
