What amendment granted women the right to vote?

The 19th Amendment, ratified in 1920, was a significant milestone in the women's suffrage movement, as it explicitly granted women the legal right to vote in the United States. This amendment marked the culmination of decades of activism and advocacy by women who campaigned tirelessly for equal voting rights. The amendment's passage represented a crucial victory in the struggle for gender equality and ensured that citizenship was no longer contingent upon gender.

In contrast, the 15th Amendment, ratified in 1870, addressed voting rights for African American men but did not extend the same rights to women. The 24th Amendment, ratified in 1964, prohibited poll taxes in federal elections, further protecting voting rights but not specifically regarding women's suffrage. The 26th Amendment, ratified in 1971, lowered the voting age to 18 but also did not relate to women's right to vote. Therefore, the 19th Amendment is the correct answer as it directly pertains to granting women the right to participate in elections.
