The Eighteenth Amendment

"Section 1.

After one year from the ratification of this article the manufacture, sale, or transportation of intoxicating liquors within, the importation thereof into, or the exportation thereof from the United States and all territory subject to the jurisdiction thereof beverage purposes is hereby prohibited. 

Section 2.

The Congress and the several States shall have concurrent power to enforce this article by appropriate legislation. 

Section 3.

This article shall be inoperative unless it shall have been ratified as an amendment to the Constitution by the legislatures of the several States, as provided in the Constitution, within seven years from the date of submission hereof to the States by the Congress."

This amendment has to do with the prohibition of alcohol.  It was amended to the Constitution because it was thought that getting rid of alcohol would put an end to the problem.  It also had a lot to do with taxes and the sixteenth amendment.  This amendment made it illegal to import or export any alcohol.  

This image shows how many people were against the prohibition of alcohol, and how willing people were to campaign and get it back.  

This image is just an article showing the date that all states ratified the prohibition of alcohol and how it was called a "momentous day in world's history" which I am guessing is because it was so outrageous.
