Answer:
The 19th Amendment
Step-by-step explanation:
The Nineteenth Amendment to the Constitution of the United States prohibits states and the federal government from denying the right to vote to United States citizens on the basis of sex. It was ratified on August 18, 1920. Until the 1910s, most states did not give women the right to vote. The change was the culmination of the women's suffrage movement in the United States, which fought at the state and national levels to reach the vote.
