In what year was the 19th amendment, which granted women the right to vote, passed?

The 19th Amendment, which granted women the right to vote in the United States, was officially ratified on August 18, 1920, and certified on August 26 of the same year. This significant milestone in the women's suffrage movement marked a pivotal moment in American history, as it secured voting rights for women after decades of activism and struggle. The amendment's passage was the culmination of efforts by many advocates advocating for gender equality and civic participation, ultimately leading to the constitutional guarantee that women would not be denied the right to vote based on sex. Therefore, the correct answer is 1920, not 1919, 1918, or 1921. These dates were significant in the suffrage movement's timeline, but they do not reflect the year the amendment was ratified.
