Which amendment to the U.S. Constitution protects the right to vote regardless of race?

The 15th Amendment to the U.S. Constitution specifically prohibits the federal and state governments from denying a citizen the right to vote based on "race, color, or previous condition of servitude." Ratified in 1870, this amendment was a significant milestone in American history, particularly during the Reconstruction era, as it aimed to ensure that African American men and other minority groups could participate in elections following the Civil War.

By establishing this protection, the 15th Amendment was instrumental in advancing voting rights and challenged discriminatory practices that had been prevalent. It laid the groundwork for subsequent civil rights legislation and amendments that further sought to expand and protect the right to vote for all U.S. citizens, regardless of race. This context underscores why the 15th Amendment is recognized as the amendment that directly addresses racial discrimination concerning voting rights.
