Which amendment to the Constitution granted women the right to vote?

The 19th Amendment to the Constitution is significant as it explicitly granted women the legal right to vote. Ratified in 1920, this amendment marked a pivotal victory in the women's suffrage movement, which sought to ensure that women had the same voting rights as men. Prior to the 19th Amendment, women's rights to vote were largely denied throughout the United States. The amendment was the culmination of years of activism and campaigning, reflecting a changing societal view on gender equality and the role of women in civic life.

The other amendments mentioned do not pertain to women's voting rights: the 15th Amendment addresses the voting rights of African American men, the 26th Amendment lowers the voting age to 18, and the 14th Amendment deals primarily with civil rights and equal protection under the law. Thus, the 19th Amendment stands out as the critical change that enfranchised women and reshaped American democracy.
