Final answer:
In the Progressive Era, political rights expanded through state-level and national-level reforms, including suffrage, regulations, and civil rights movements.
Step-by-step explanation:
In the Progressive Era, political rights expanded for regular people through a variety of state-level and national-level reforms. Grassroots Progressives advocated for direct democracy, leading to the passage of state-level reforms that expanded suffrage. At the national level, legislative and constitutional changes were made to address social problems, such as regulating trusts and monopolies, guaranteeing consumer safety, pursuing labor abuses, and stabilizing the banking system.
Furthermore, the Progressive Era also saw the growth of movements for civil rights for African Americans and women's suffrage. African Americans identified an agenda for civil rights and economic opportunity, while the women's movement cultivated leaders and organizations advocating for women's rights, including the right to vote.
Overall, the Progressive Era was characterized by efforts to promote a more perfect democracy, address social inequities, and expand political rights for regular people.
