This activity explores the Supreme Court case Guinn v. United States (1915) and its impact on voting rights and government power. Students will learn how the Court ruled against Oklahoma’s “grandfather clause,” which unfairly restricted voting rights for Black citizens. The case shows how the government used the Constitution—especially the 15th Amendment—to protect individual freedoms and stop discriminatory laws. Guinn v. United States highlights the role of the courts in defending citizens’ right to vote and continues to spark conversations about civil rights, equal access to voting, and the balance between state laws and constitutional protections.
