What did the eighteenth amendment to the us constitution accomplish?

What the Eighteenth Amendment to the US Constitution accomplished was that it banned the production, sale, and transportation of alcohol in the US. Prior to the writing of this amendment, there were several "temperance" groups consisting mostly of women who wanted to ban alcohol within America because of all the negative side-effects it has. In time, this movement led to the actual amendment being written and adopted, although it was repealed in 1933.
