Progressives were a diverse group of reformers in the late 19th and early 20th centuries who sought to address the social, political, and economic challenges posed by industrialization, urbanization, and corruption in government. They believed in using government action to improve society and aimed to create a more equitable distribution of wealth, enhance democratic governance, and promote social justice. This ideology significantly influenced policy making and economic policy, shaping the direction of American politics during this transformative era.
