Which amendment granted women the right to vote in the United States?

The 19th Amendment, ratified in 1920, is the amendment that granted women the legal right to vote in the United States. This significant change in the Constitution marked the culmination of decades of activism and struggle by women suffragists, who advocated for equal voting rights as a fundamental aspect of democracy and equality. The 19th Amendment removed any federal or state restrictions on voting based on sex, thus ensuring that women could participate fully in the electoral process.
