The 15th Amendment to the United States Constitution was ratified on February 3, 1870. It was a pivotal moment in Black history as it granted African American men the right to vote. The amendment states that the right 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 step forward in the fight for civil rights and racial equality in the United States. It was a direct result of the abolition of slavery following the Civil War and the Reconstruction era that followed. However, despite the passage of the 15th Amendment, African Americans still faced many obstacles when trying to exercise their right to vote due to discriminatory practices such as poll taxes, literacy tests, and intimidation tactics.

It wasn't until the Civil Rights Movement of the 1960s that significant progress was made in securing voting rights for African Americans through legislation such as the Voting Rights Act of 1965. The 15th Amendment remains an important milestone in Black history as it marked a crucial moment in the ongoing struggle for equal rights and representation for African Americans in the United States.
