Abstract:

The America's profound socio-economic changes and transformations in the late 19^th and early 20 ^thcenturies led to the rise of the so-called Progressive Movement, whose advocates and supporters came from major American social classes and groups. Common senses of social responsibility and anx-iousness tied those progressive reformers together, and made them dedicated to their cause. As both a successor to and a pillar of the liberal tradition in American history, the Progressive Movement contributed a lot though it borrowed much from all kinds of social reform practice. Due to the complexity of then American society in transition, the story of Progressivism contains many paradoxes that need examining thoroughly.

Key words: U. S. A., society in transition, Progressive Movement, reform
