Which amendment granted women the right to vote?

The amendment that granted women the right to vote is the 19th Amendment. Ratified in 1920, this amendment states that the right to vote shall not be denied or abridged on account of sex, effectively granting women equal voting rights with men. This was a significant milestone in the women's suffrage movement, which had been advocating for women's rights in the United States for decades.

The other amendments mentioned are related to voting but do not pertain specifically to women's suffrage. The 15th Amendment prohibits denying a citizen the right to vote based on race, color, or previous condition of servitude, but it does not address gender. The 24th Amendment prohibits poll taxes in federal elections, and while it aimed to eliminate economic barriers to voting, it also does not relate directly to women's right to vote. The 1st Amendment guarantees freedoms concerning religion, expression, assembly, and the right to petition the government, but it does not specifically include voting rights. Therefore, the 19th Amendment is clearly recognized as the legislation that secured voting rights for women in the United States.
