Final answer:
Women in the United States were nationally recognized as having the right to vote in 1920 with the ratification of the 19th Amendment. Wyoming was the first state to grant full voting rights to women in 1869, and this right became nationally recognized after decades of advocacy by women's suffrage movements.
Step-by-step explanation:
The year women were nationally recognized as having the right to vote was 1920, which marked a pivotal moment in the women's suffrage movement. Before this landmark year, only certain states had granted women this right. Wyoming, known as "the Equality State," was the first to grant full voting rights to women in 1869. This right was only recognized nationally with the ratification of the 19th Amendment in August 1920. Women's suffrage activists, including Carrie Chapman Catt and Alice Paul, cast their first ballots in a presidential election in November 1920. The National American Woman Suffrage Association (NAWSA), formed in 1890 by women's rights pioneers including Stanton and Anthony, played a significant role in winning this right, shifting strategies from advocating equality to linking suffrage to women's traditional caretaker roles.
