What social movement is characterized by the advocacy against alcohol consumption in the early 20th century?

The Temperance Movement is indeed characterized by advocacy against alcohol consumption in the early 20th century. This movement began in the 19th century and gained significant momentum leading up to Prohibition in the 1920s. Its primary goal was to limit or eliminate the use of alcoholic beverages, which advocates believed were the cause of various social issues, including domestic violence, poverty, and moral decay. Organizations such as the Woman's Christian Temperance Union and the Anti-Saloon League were instrumental in promoting the message of temperance and lobbying for laws to restrict alcohol sales and consumption. Ultimately, this movement led to the ratification of the 18th Amendment in 1919, which prohibited the manufacture, sale, and transportation of alcoholic beverages in the United States.

The significance of the Temperance Movement lies in its association with broader social reform movements of the time, including women's suffrage and various Progressive Era reforms aimed at improving society through legislation and public awareness.
