Which amendment granted women the right to vote?

The amendment that granted women the right to vote is the 19th Amendment. Ratified in 1920, this amendment specifically prohibits any U.S. citizen from being denied the right to vote on the basis of sex. It represented a significant milestone in the women's suffrage movement, which fought for decades to secure voting rights for women.

The 15th Amendment, ratified in 1870, addresses voting rights but specifically focuses on prohibiting the denial of voting rights based on race, color, or previous condition of servitude, not gender. The 21st Amendment, ratified in 1933, deals with the repeal of Prohibition and has no connection to voting rights. Lastly, the 26th Amendment, ratified in 1971, lowered the voting age to 18 but does not pertain to women's voting rights. Thus, the 19th Amendment is directly responsible for granting women the right to vote in the United States.
