What amendment grants voting rights regardless of race, color, or previous condition of servitude?

The amendment that specifically grants voting rights regardless of race, color, or previous condition of servitude is the 15th Amendment. Ratified in 1870, this amendment was a significant advancement in the fight for civil rights, as it aimed to secure the right to vote for African American men following the Civil War. The language of the amendment explicitly prohibits the federal or state governments from denying a citizen's right to vote based on these characteristics, marking a crucial step towards equality in the political process.

The 12th Amendment relates to the electoral process for the President and Vice President and does not address voting rights based on race. The 13th Amendment abolished slavery and involuntary servitude, which is essential for civil rights but does not directly address voting. The 14th Amendment guarantees citizenship rights and equal protection under the law but does not explicitly mention voting rights as the 15th Amendment does.
