Which amendment granted the right to vote to all males, regardless of race or previous condition of servitude?

The correct choice is indeed the amendment that specifically prohibits the denial of the right to vote based on race or previous condition of servitude. The 15th Amendment, ratified in 1870, was a pivotal part of the Reconstruction Era legislation aimed at ensuring that African American men could participate in the electoral process following the Civil War. This amendment aimed to eliminate barriers to voting that had been used to disenfranchise Black men, reinforcing their citizenship and political rights.

The 13th Amendment abolished slavery and involuntary servitude, addressing the broader issue of freedom but not specifically voting rights. The 14th Amendment established citizenship for all persons born or naturalized in the United States and included provisions for equal protection under the law, but it did not explicitly grant voting rights. The 19th Amendment, ratified in 1920, extended the right to vote to women but is not related to the voting rights of men regardless of race. Thus, the 15th Amendment is the correct answer solely focused on voting rights for men at that time.
