What amendment granted women the right to vote in the United States?

The 19th Amendment to the United States Constitution granted women the right to vote, a significant milestone in the women's suffrage movement. Ratified in 1920, the amendment 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 decades of activism by women who campaigned for equal voting rights, highlighting the importance of women's participation in democracy.

In contrast, the other amendments listed address different rights or governmental procedures. The 17th Amendment deals with the election of U.S. Senators by direct popular vote, the 21st Amendment repealed Prohibition, and the 15th Amendment prohibits denying the right to vote based on race, color, or previous condition of servitude, but does not address gender. Understanding the 19th Amendment is crucial for recognizing the broader context of social reforms and civil rights movements in American history.
