The 15th Amendment was significant for granting voting rights to which group?

The 15th Amendment, ratified in 1870, is significant because it granted African American men the legal right to vote, specifically prohibiting the denial of the right to vote based on "race, color, or previous condition of servitude." This constitutional change was a landmark achievement for civil rights during the Reconstruction era following the Civil War. While it applied to all male citizens, the primary focus was on securing voting rights for those who had been previously excluded from the electoral process due to systemic discrimination.

In this context, the amendment did not extend voting rights to women, who continued to fight for suffrage for several more decades. Children are not considered eligible voters, and the amendment does not address voting rights for Native American tribes, as they were often at that time considered outside the purview of U.S. citizens and the constitution. Thus, the correct answer reflects the primary intent and impact of the 15th Amendment in extending voting rights to universal male citizens, particularly addressing the enfranchisement of African American men who had previously been denied that right.
