Women's suffrage: The women's suffrage movement also played a significant role in the push for prohibition. Many suffragists believed that alcohol was a major obstacle to women's rights and suffrage. They argued that alcohol contributed to domestic violence, poverty, and other societal problems that affected women disproportionately. As women gained more political influence through suffrage, they became a powerful force in the prohibition movement.
Progressive movement: The Progressive movement, which aimed to reform society and promote social justice, also supported prohibition. Progressives viewed alcohol as a threat to public health, morality, and social progress. They argued that prohibition would reduce crime, improve public health, and strengthen families and communities.
World War I: The entry of the United States into World War I in 1917 further contributed to the momentum for prohibition. The war effort required the conservation of resources, and alcohol was seen as a luxury that could be sacrificed. Additionally, concerns about the impact of alcohol on the health and efficiency of soldiers and workers in the war industries fueled support for prohibition.
These factors combined to create a strong political consensus in favor of prohibition, leading to the ratification of the 18th Amendment to the United States Constitution in 1919, which prohibited the manufacture, sale, and transportation of alcohol.
