How did World War 1 contribute to the nineteenth amendment?

World War I played a significant role in the passage of the Nineteenth Amendment, which granted women the right to vote in the United States. During the war, women took on roles traditionally held by men, working in factories and serving in various capacities to support the war effort. This shift demonstrated women’s capabilities and contributions to society, leading to increased support for women's suffrage. Additionally, the war fostered a sense of national unity and progressivism, helping to sway public opinion and political will in favor of women’s voting rights.
