Which amendment granted women the right to vote?

The 19th Amendment to the United States Constitution is the correct answer, as it specifically granted women the right to vote. Ratified on August 18, 1920, this amendment marked a significant milestone in the women's suffrage movement, which advocated for equal voting rights for women. The language of the amendment clearly states that the right to vote shall not be denied on the basis of sex, thereby officially establishing women's suffrage at the federal level in the United States.

Understanding this context is essential, as the other amendments listed address different voting rights issues. The 15th Amendment, for example, was ratified in 1870 and aimed to protect the voting rights of African American men, prohibiting discrimination based on race. The 24th Amendment, ratified in 1964, eliminated poll taxes in federal elections, ensuring that financial barriers could not prevent individuals from voting. Lastly, the 26th Amendment, ratified in 1971, lowered the voting age from 21 to 18, extending voting rights to a younger demographic. Each of these amendments contributes to the larger tapestry of voting rights in the U.S., but the 19th Amendment distinctly focuses on women's right to vote.
