The movement aimed at reforming society through the abolition of alcohol is known as the Temperance Movement, which gained momentum in the 19th and early 20th centuries. Advocates believed that alcohol consumption led to societal issues such as crime, domestic violence, and poverty. The movement was fueled by various social and religious groups, most notably the Women’s Christian Temperance Union (WCTU). The culmination of this movement was the passage of the 18th Amendment to the U.S. Constitution, which prohibited the manufacture and sale of alcohol from 1920 until its repeal in 1933. It marked a significant social experiment with far-reaching impacts on American society.
