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

The 19th Amendment to the United States Constitution, ratified in 1920, granted women the legal right to vote. This significant amendment emerged from a long-fought battle for women's suffrage, reflecting the changing attitudes towards gender equality and the role of women in society. Activists and suffragists worked tirelessly for decades, advocating for women's rights and ultimately culminated in this landmark achievement, allowing women to participate fully in the democratic process by voting in elections.

The other amendments listed do not pertain specifically to women's voting rights. The 15th Amendment focuses on prohibiting the denial of the right to vote based on race, color, or previous condition of servitude. The 24th Amendment addresses the prohibition of poll taxes in federal elections, and the 26th Amendment lowers the voting age to 18. Each of these amendments serves important functions in expanding voting rights, but it was the 19th Amendment that specifically enfranchised women.
