Which amendment was a major achievement for the temperance movement?

The 18th Amendment, ratified in 1919, was a major achievement for the temperance movement as it prohibited the manufacture, sale, and transportation of Alcoholic Beverages in the United States. This amendment marked the culmination of decades of advocacy by temperance activists who sought to address the social issues associated with alcohol consumption. However, it ultimately led to unintended consequences, including the rise of organized crime and the eventual repeal of the amendment with the 21st Amendment in 1933.
