Which amendment granted African American men the right to vote?

The Fifteenth Amendment is significant because it 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 crucial milestone in the struggle for civil rights, as it aimed to ensure that African American men could participate in the electoral process following the Civil War.

Other amendments mentioned do not directly pertain to the voting rights of African American men. The Fourteenth Amendment addresses citizenship and equal protection under the law but does not explicitly grant voting rights. The Sixteenth Amendment deals with income tax and is unrelated to voting. The Nineteenth Amendment, on the other hand, granted women the right to vote, highlighting the ongoing struggle for voting rights across different demographics but not focusing on African American men specifically. Thus, the Fifteenth Amendment plays a foundational role in the history of voting rights for African American men in the United States.
