Answer :
It was technically women who received the right to vote last, but it should be noted that many impediments existed for African Americans in voting long after it was technically made legal.
The correct answer is all women.
African-American men were granted the right to vote with the 15th amendment in 1870. However, women were not granted the right to vote until 1920. Women gained the right to vote with the 19th amendment of the US Constitution. This was the last group to technically get the legal right to vote, even though many African American men were limited by laws in Southern states like grandfather clauses, poll taxes, and literacy tests.
