Final answer:
The 15th Amendment gave Black men the right to vote in the United States.
Step-by-step explanation:
The 15th Amendment to the United States Constitution gave Black men the right to vote. It was ratified in 1870 and aimed to protect the voting rights of African American men following the Civil War. This amendment prohibited the denial of the right to vote based on race, color, or previous condition of servitude. However, it did not grant suffrage to Black women, and it was not until the 19th Amendment in 1920 that women were granted the right to vote.
