Which amendment granted women the right to vote?

The 19th Amendment to the United States Constitution, ratified in 1920, is the pivotal amendment that granted women the right to vote. This landmark change was the result of a long-fought battle by women’s suffrage activists who campaigned for equal voting rights. The amendment ensures that the right to vote cannot be denied or abridged on the basis of sex, effectively acknowledging women's eligibility to participate in elections at all levels of government.

In contrast, the other amendments mentioned are associated with different voting rights. The 15th Amendment focuses on prohibiting the denial of voting rights based on race, color, or previous condition of servitude, while the 24th Amendment abolished poll taxes in federal elections, removing a financial barrier that disproportionately affected low-income voters, often including African Americans. The 26th Amendment lowered the voting age from 21 to 18 years, ensuring that younger citizens could also engage in the electoral process. Each of these amendments plays a distinct role in the evolution of voting rights in America, but it is the 19th Amendment that specifically addresses women's suffrage.
