During the Progressive Era in America, which spanned from the 1890s to the 1920s, significant changes included reforms aimed at addressing social issues caused by industrialization, urbanization, and political corruption. Reformers advocated for women's suffrage, labor rights, and regulations on monopolies, leading to the establishment of laws for child labor protection, food safety standards, and antitrust regulations. The era also saw increased engagement in politics, with the introduction of initiatives, referendums, and direct primaries. Ultimately, these changes sought to enhance democratic governance and improve living conditions for Americans, reflecting a growing commitment to social justice and governmental accountability.
