The 15th Amendment to the United States Constitution was passed on February 3, 1870, and granted African American men the right to vote. The amendment stated that the "right of citizens of the United States to vote shall not be denied or abridged by the United States or by any State on account of race, color, or previous condition of servitude."

This amendment was a significant milestone in Black history as it officially granted African American men the right to participate in the political process and have a say in the governance of the country. This was a crucial step towards equality and civil rights for African Americans, as voting rights are essential to full participation in a democratic society.

While the 15th Amendment was a momentous achievement, it did not guarantee equal voting rights for all African Americans. Many states implemented discriminatory practices such as poll taxes, literacy tests, and intimidation tactics to prevent Black people from exercising their right to vote. It was not until the Voting Rights Act of 1965 that these barriers were effectively dismantled, and African Americans were able to fully exercise their voting rights.

Overall, the 15th Amendment was a significant moment in Black history, marking a step towards greater political inclusion and equality for African Americans in the United States.
