Over time, the idea of who belongs and who can participate in government broadened from a narrow, colonial pattern to a federally defined membership. In colonial times, voting and citizenship were limited to a small group—typically free white men with property or certain wealth qualifications—and there wasn’t a single national standard. After the Civil War, a series of amendments redefined membership and rights: the 13th ended slavery, the 14th made anyone born or naturalized in the U.S. a citizen with equal protection under the law, and the 15th barred denying the vote because of race or former enslavement. This established citizenship and voting rights for formerly enslaved people. While the struggle to make these rights real continued (due to discriminatory practices and other barriers), the framework created during Reconstruction opened eligibility in law and set the stage for further expansion, including women’s suffrage later on with the 19th Amendment.
