Which amendment granted women the right to vote?

The 19th Amendment is significant as it specifically grants women the right to vote in the United States. Ratified in 1920, this amendment was a major milestone in the women's suffrage movement, which sought to eliminate the legal barriers preventing women from participating fully in the electoral process. The passage of the 19th Amendment was the result of decades of activism and advocacy by women and their allies, highlighting the importance of gender equality in civic participation.

In contrast, the other amendments listed do not address women's voting rights. The 15th Amendment focuses on prohibiting the denial of the right to vote based on race, the 24th Amendment addresses voting rights in the context of federal elections and prohibits poll taxes, while the 1st Amendment ensures freedoms such as speech, religion, and assembly but does not specifically relate to voting rights.
