Cyclical theory (United States history) (original) (raw)

The cyclical theory refers to a model used by historians Arthur M. Schlesinger Sr. and Arthur M. Schlesinger Jr. to explain the fluctuations in politics throughout American history. In this theory, the United States's national mood alternates between liberalism and conservatism. Each phase has characteristic features, and each phase is self-limiting, generating the other phase. This alternation has repeated itself several times over the history of the United States. Several other cycles of American history have been proposed, with varying degrees of support.
