What right did the 15th Amendment grant?

The 15th Amendment, ratified in 1870, specifically addresses voting rights by prohibiting the federal and state governments from denying a citizen the right to vote based on "race, color, or previous condition of servitude." This amendment was a significant step toward ensuring that African American men could participate in the electoral process following the Civil War, reflecting the effort to secure voting rights for individuals who had historically been marginalized and disenfranchised.

The options related to women's voting rights, income tax collection, and the direct election of Senators refer to different constitutional amendments and legislative changes. Women's right to vote was granted by the 19th Amendment in 1920. The 16th Amendment established the income tax collection by the federal government, and the 17th Amendment allowed for the direct election of Senators. Each of these amendments addresses separate and distinct areas of voting rights and governance, further emphasizing the specific focus of the 15th Amendment on racial equality in voting.
