Key Concepts

The 15th Amendment

During Reconstruction, Congress passed the 15th Amendment on February 26, 1869 and it was ratified on February 3, 1870. The amendment barred the denying or abridging of a citizen’s right to vote “on account of race, color, or previous condition of servitude,” and granted the Congress the power to enforce it through “appropriate legislation.” No longer could citizens be disenfranchised because of their race by northern or southern states by law.

Legacy of 15th Amendment

The 15th Amendment, however, was limited. It did not provide protections against discrimination based on sex or economics, leaving the door open for states to exclude women and the impoverished from the polls and from being full citizens and participants in American democracy. Furthermore, the 15th Amendment did not prevent states from using the 15th Amendment’s loopholes and other ways to disenfranchise African Americans, including “grandfather clauses” and literacy tests, or violence and intimidation. It would take organizing, picketing, marching, incarceration, and enduring or succumbing to violence to protect and expand suffrage, resulting in the 19th Amendment to protect women’s right to vote, the 24th Amendment to eliminate the poll tax, and the Voting Rights Act of 1965 to enforce the 15th Amendment and close the loopholes.

Relevant Cases or Laws

United States v. Reese (1876)

The Supreme Court struck down the Enforcement Act of 1870 as an unconstitutional law passed to enforce the 15th Amendment. The Court held that the 15th Amendment did not protect the vote, but instead was focused on preventing racial discrimination. The Enforcement Act, created to prevent intimidation of and violence against African Americans exercising their civil and political rights, was not narrowly tailored to only focus on discrimination based on race at the polls.

Voting Rights Act of 1965

Signed into law on August 6, 1965, the Voting Rights Act represented the culmination of Civil Rights organizing to protect suffrage and eliminate discrimination and disenfranchisement. It outlawed literacy tests and provided for federal oversight of registration and voting in some southern states and for preclearance of election laws or changes to them. Learn More
