The group of people most directly affected by the 15th Amendment were African Americans. Here's why:
1. The 15th Amendment, ratified in 1870, granted African American men the right to vote. This amendment aimed to ensure that race would not be a barrier to voting rights.
2. Prior to the 15th Amendment, many states had laws and practices in place that disenfranchised African Americans, denying them the right to vote based on their race.
3. The passage of the 15th Amendment was a significant step forward in the fight for civil rights and equality for African Americans, though challenges and obstacles to voting rights persisted.
Overall, the 15th Amendment played a crucial role in advancing the rights of African Americans by granting them the constitutional right to vote, marking an important milestone in the ongoing struggle for equality and civil rights in the United States.
