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 significant piece of legislation marked a pivotal moment in the fight for women's suffrage in the United States. It states clearly that the right to vote cannot be denied on the basis of sex, which finally provided women with legal recognition of their right to participate in electoral processes. This amendment was the culmination of decades of activism and struggle by women's rights advocates, highlighting the long and difficult journey toward achieving gender equality in voting rights.

In contrast, the 15th Amendment primarily addresses voting rights regardless of race, color, or previous condition of servitude, and does not mention gender. The 21st Amendment deals with the repeal of Prohibition, and the 23rd Amendment grants residents of Washington, D.C. the right to vote in presidential elections, none of which pertain to women's suffrage.
