What is the 18th Amendment in simple terms?

The 18th Amendment, known as Prohibition (1919-1933), banned making, selling, or transporting alcoholic drinks in the U.S., driven by temperance movements to curb societal problems from drinking, but it led to organized crime, corruption, and was eventually repealed by the 21st Amendment, leaving alcohol laws to states.

The 18th Amendment (Prohibition) was overturned by the 21st Amendment in 1933 because it failed miserably, leading to massive organized crime (Al Capone, St. Valentine's Day Massacre), widespread defiance, rampant corruption, and a huge loss of public support, especially during the Great Depression when tax revenue from alcohol was desperately needed. The federal government couldn't effectively enforce it, and the public realized it created more problems than it solved, making repeal a popular political goal.
