Which amendment granted African American men the right to vote?

The 15th Amendment, ratified in 1870, specifically addresses the voting rights of citizens and prohibits the federal and state governments from denying a citizen the right to vote based on "race, color, or previous condition of servitude." This amendment was a significant milestone in the fight for civil rights, as it aimed to secure the voting rights of African American men after the Civil War.

In contrast, the 13th Amendment abolished slavery, while the 14th Amendment granted citizenship to all persons born or naturalized in the United States and included provisions for equal protection under the law, but it did not explicitly guarantee the right to vote. The 19th Amendment, ratified in 1920, granted women the right to vote, expanding voting rights further but not specifically to African American men.
