The main focus of the Progressive Era in the United States, spanning roughly from the 1890s to the 1920s, was to address the social, political, and economic issues arising from industrialization, urbanization, and corruption. Reformers aimed to improve societal conditions through various initiatives, including labor rights, women's suffrage, antitrust legislation, and public health reforms. The movement sought to reduce the power of monopolies and improve democratic governance, leading to significant changes like the direct election of senators and the establishment of regulatory agencies. Notable figures of the Progressive Era include Theodore Roosevelt and Jane Addams, whose contributions helped shape modern America and emphasized the importance of social welfare and civic responsibility.
