Which amendment granted women the right to vote?

The 19th Amendment, ratified in 1920, is significant because it explicitly states that the right to vote cannot be denied on the basis of sex, thereby granting women the legal right to participate in elections. This amendment was the culmination of a long and difficult struggle for women's suffrage in the United States, with activists campaigning for decades to secure this basic civil right.

The other amendments listed do not specifically address women's voting rights. The 15th Amendment prohibits denying the right to vote based on race but does not mention gender. The 23rd Amendment grants residents of Washington, D.C., the right to vote in presidential elections, and the 26th Amendment lowers the voting age to 18 but does not relate to gender rights. Understanding the purpose and impact of the 19th Amendment is crucial in recognizing the advancements made in voting rights and gender equality in the U.S.
