The Progressive Era was a period of social activism and political reform in the United States that spanned from the 1890s to the 1920s. Caused by cultural decline, muckrakers exposing issues, and economic changes from industrialization, progressives fought for reforms addressing issues like corruption, child labor, women's suffrage, and prohibition. Key leaders included Theodore Roosevelt, Woodrow Wilson, and Robert LaFollette. Roosevelt proposed a New Nationalism with trust busting and consumer protections. Wilson advocated a New Freedom through antitrust acts and the Federal Reserve. Women and African Americans also led important reform movements during this era of social change.
