Prohibition in the United States
1920 to 1933
Although the Eighteenth Amendment to the US Constitution and the Volstead Act were enacted in 1920 there was a vigorous campaign for prohibition many years before 1920.
I came across a 1913 newspaper from Alabama which might give you a little bit more insight into why the amendment was adopted.

Here are some of the articles in the newspaper:
The Anti-Saloon League Convention
Eighty-one Pupils in School Drunk
A Trail of Blood Increase of Crime from Records
The Physiological Effect of Alcohol

If you would like to learn more about the history of prohibition you can always go to the Wikipedia web page:

From Wikipedia, the free encyclopedia

I understand there is also a documentary available:

A Film by Ken Burns and Lynn Novick
I hope this little bit of 1913 history will add to your understanding of why prohibition became the law.
Thank You.
Thanks – I enjoy your posts. An excellent book also on this topic is Southern Prohibition: Race, Reform, and Public Life in Middle Florida, 1821-1920

Wonder how many young men came home from WWI with a “drinking problem”? I think of all the vets we have coming home now who are emotional wrecks, and the help offered to them. It’s not nearly enough, but I’m betting it’s 100x more than boys of this era were offered upon their return.
Do you suppose that there was a link between the soldiers returning home and the support of the prohibition laws?
