What did th 18 amendment prohibit when it was ratified in 1919?

The 18th Amendment, ratified in 1919, prohibited the manufacture, sale, and transportation of Alcoholic Beverages in the United States. This marked the beginning of Prohibition, a nationwide constitutional ban aimed at reducing alcohol consumption and its associated social issues. However, the amendment proved difficult to enforce and led to a rise in illegal activities, ultimately resulting in its repeal by the 21st Amendment in 1933.
