Which constitutional amendment granted women the right to vote?

The 19th Amendment to the United States Constitution granted women the right to vote, which was a significant achievement in the women's suffrage movement. Ratified in 1920, this amendment states that the right to vote shall not be denied or abridged on account of sex, ensuring that women could participate equally in elections and the democratic process. The passage of this amendment was the culmination of decades of activism aimed at securing voting rights for women, making it a landmark moment in American history and a fundamental progression towards gender equality in voting rights.

In contrast, the other amendments mentioned have different focuses; the 15th Amendment is concerned with voting rights regardless of race, the 24th Amendment abolished poll taxes in federal elections, and the 26th Amendment lowered the voting age to 18. Each of these amendments contributes to the expansion of voting rights in different ways, but it is the 19th Amendment specifically that enshrined the right to vote for women.
