Four main detailed concept of the progressive era

1. Social Reform: One of the main focuses of the Progressive Era was social reform, particularly in areas such as women's rights, labor rights, and racial equality. Activists and reformers worked to address issues such as child labor, poor working conditions, and the lack of rights for minority groups.

2. Political Reform: Progressives advocated for political reforms to make government more responsive to the needs of the people. They pushed for initiatives such as direct primaries, the initiative, referendum, and recall, and the direct election of senators, which aimed to make the political process more transparent and democratic.

3. Economic Reform: Progressive reformers also sought to address the economic inequalities and abuses that were prevalent during the Gilded Age. They advocated for antitrust laws, regulations on big business, and reforms to the banking and financial sectors in order to promote fair competition and protect consumers.

4. Conservation and Environmental Reform: Progressives were also concerned with conservation and environmental issues, as industrialization and urbanization were taking a toll on the country's natural resources. They worked to establish national parks, forests, and wildlife refuges, as well as regulations to protect clean air and water. Teddy Roosevelt was a notable supporter of conservation efforts during this time.
