Which amendment guarantees women the right to vote?

The 19th Amendment to the United States Constitution is the one that guarantees women the right to vote. Ratified in 1920, it states that the right to vote cannot be denied or abridged on account of sex. This amendment was the culmination of decades of activism by women's suffrage movements, which fought for equality in voting rights.

The significance of the 19th Amendment lies in its role in expanding democracy and ensuring that women's voices are equally represented in the electoral process. Prior to this amendment, many women were denied the fundamental right to participate in elections solely based on their gender. The ratification of the 19th Amendment marked a pivotal moment in U.S. history, allowing women to fully engage in the political system and influencing future movements for equal rights.
