Which amendment provided African American men with the right to vote?

The 15th Amendment to the United States Constitution is the one that granted African American men the right to vote. Ratified in 1870, this amendment specifically prohibits the federal and state governments from denying a citizen the right to vote based on "race, color, or previous condition of servitude." This was a crucial step in the post-Civil War era, as it aimed to ensure that African American men, who had been enslaved and denied various rights, were allowed to participate in the democratic process.

The 13th Amendment abolished slavery and involuntary servitude, while the 14th Amendment granted citizenship and equal protection under the law to all persons born or naturalized in the United States, which also included African Americans. However, it was the 15th Amendment that explicitly focused on voting rights. The 16th Amendment pertains to income tax and does not relate to voting rights. Therefore, the 15th Amendment is clearly the amendment that established voting rights for African American men.
