At the end of the Reconstruction, the spread of science and technology, industrialism, urbanization, immigration, and economic depressions eroded Americans' conventional beliefs in individualism and a divinely ordained social system. In The Search for Order, 1877-1920, Robert H. Wiebe shows how, in subsequent years, during the Progressive Era of Theodore Roosevelt and Woodrow Wilson, Americans sought the organizing principles around which a new viable social order could be constructed in the modern world. This subtle and sophisticated study combines the virtues of historical narrative, sociological analysis, and social criticism.
