What amendment granted women the right to vote?

The 19th Amendment is significant because it explicitly grants women the right to vote in the United States. Ratified in 1920, this amendment declared that the right to vote shall not be denied or abridged on account of sex. This was a monumental achievement in the women's suffrage movement, which fought tirelessly for decades to secure this fundamental right.

In contrast, the other amendments listed play different roles in voting rights. The 15th Amendment, for example, focuses on prohibiting the denial of voting rights based on race. The 21st Amendment is about repealing Prohibition and has no relevance to voting rights, while the 24th Amendment prohibits poll taxes in federal elections, which was another barrier to voting, but it does not specifically address women's suffrage. The 19th Amendment remains the pivotal milestone in providing women with equal voting rights.
