Which amendment granted women the right to vote?

The Nineteenth Amendment is significant because it officially granted women the right to vote in the United States, a pivotal change in the constitutional framework regarding suffrage. Ratified in 1920, this amendment marked the culmination of a lengthy struggle for women's rights that involved decades of activism, protests, and advocacy. The amendment specifically states, "The right of citizens of the United States to vote shall not be denied or abridged by the United States or by any State on account of sex." This fundamental change ensured that women could participate equally in the democratic process, addressing longstanding issues of gender inequality in electoral rights.

In contrast, the other amendments listed address different aspects of voting and governance. The Sixteenth Amendment deals with income tax, the Twenty-First Amendment focuses on the repeal of Prohibition, and the Twenty-Fourth Amendment prohibits poll taxes in federal elections, none of which pertain directly to granting women the right to vote.
