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

The 19th Amendment, ratified in 1920, states that the right to vote shall not be denied on the basis of sex. This landmark amendment granted women in the United States the legal right to participate in elections, marking a significant victory in the women’s suffrage movement. The amendment symbolized a shift towards gender equality in voting rights, acknowledging women's contributions to society and politics.

In contrast, the 17th Amendment, ratified in 1913, concerns the direct election of U.S. senators, making changes to how senators are selected rather than addressing voting rights for women. The 21st Amendment, ratified in 1933, dealt with the repeal of Prohibition and does not pertain to voting rights at all. Lastly, the 15th Amendment, ratified in 1870, prohibits denying the right to vote based on race, color, or previous condition of servitude, but it does not grant women the right to vote. Therefore, the 19th Amendment is recognized as the critical legal provision that enfranchised women in the United States.
