How did World War I impact the women's suffrage movement?

The women's suffrage movement gained significant momentum during World War I, largely due to the essential roles women played while men were away fighting. As women took on jobs traditionally held by men, such as in factories, transportation, and other essential services, they demonstrated their capability and the necessity of their involvement in public life.

This shift in societal roles showcased women's contributions not only to the war effort but also to the nation as a whole. The work women did during the war helped change perceptions about gender roles and increased support for their right to vote. The argument that women who contribute to the country through their labor and sacrifice deserve a voice in government gained traction, ultimately leading to increased advocacy for women's suffrage.

When the war ended, the National American Woman Suffrage Association (NAWSA) successfully leveraged the argument that women's participation in the war effort justified the extension of voting rights. This culminated in Congress passing the Nineteenth Amendment in 1920, granting women the right to vote. Thus, the contributions made by women during World War I played a pivotal role in advancing the cause of women's suffrage, making this option the correct answer.
