Which amendment granted women the right to vote?

The 19th Amendment, ratified in 1920, is the amendment that granted women the legal right to vote in the United States. This significant change followed decades of activism and the women's suffrage movement, which played a vital role in advocating for women's rights. The passage of the 19th Amendment marked a crucial turning point in American history, solidifying the principle that voting rights cannot be denied based on gender.

The other amendments mentioned have different focuses. The 15th Amendment prohibits the denial of the right to vote based on race, color, or previous condition of servitude but does not specifically address gender. The 24th Amendment, ratified in 1964, eliminated poll taxes in federal elections, which were often used to disenfranchise voters, particularly African Americans. Lastly, the 26th Amendment, ratified in 1971, lowered the voting age to 18 years but also does not pertain to women's voting rights. Thus, the 19th Amendment is uniquely recognized for granting women the right to vote.
