Which amendment to the Constitution provides the right to vote regardless of race?

The 15th Amendment to the United States Constitution specifically addresses the right to vote and 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, it was a crucial part of Reconstruction efforts aimed at securing voting rights for former slaves after the Civil War. This amendment laid the groundwork for future civil rights legislation and was instrumental in expanding suffrage in the United States.

The other amendments mentioned address different aspects of voting rights: the 19th Amendment grants women the right to vote, the 24th Amendment prohibits poll taxes in federal elections, and the 26th Amendment lowers the voting age to 18. Each of these amendments plays a vital role in the progression of voting rights in the U.S., but none specifically targets the issue of race in the same manner as the 15th Amendment.
