Which amendment granted women the right to vote?

The 19th Amendment is significant as it specifically granted women the legal right to vote, marking a crucial victory in the women's suffrage movement in the United States. Ratified on August 18, 1920, it 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 amendment was the culmination of extensive advocacy, protests, and campaigns by women and their allies who fought for equal voting rights in the years leading up to its passage.

Understanding the context of the other amendments can help clarify why the 19th is the correct answer. The 15th Amendment, ratified in 1870, prohibits the denial of the right to vote based on race, color, or previous condition of servitude, but it does not address gender. The 24th Amendment, ratified in 1964, prohibits poll taxes in federal elections, and the 26th Amendment, ratified in 1971, lowers the voting age to 18. While all these amendments relate to voting rights, the 19th clearly and specifically focuses on women's suffrage.
