The Progressive Movement was a social and political movement in the United States during the late 19th and early 20th centuries. It aimed to address the issues caused by industrialization, urbanization, and corruption in government. Reformers sought to improve living conditions, promote labor rights, and expand democracy through various initiatives. Key figures in the movement included Theodore Roosevelt and Jane Addams, who advocated for reforms such as women's suffrage and child labor laws. The movement led to significant changes in American society, including the establishment of regulatory agencies and the implementation of social welfare programs.
