Prohibition was the banning of production, transport and consumption of alcohol under the 18th amendment passed in 1920. Prohibition was instigated for several reasons. Firstly, a lot of alcohol - particularly beer - was produced in Germany, and it was seen as unpartriotic to drink this so soon after the war. Secondly, the anti-salloon league and Christian Temperance Movements both campaigned strongly against consuming alcohol as they saw it as a root for crime, unhappy family life, an inability to work correctly and as agaist God. Finally, through cutting the production of alcohol grains such as barley could be saved. Prohibition failed for a number of reasons, primarily that there were not enough prohibition agents to enforce the laws and control the growing organised crime that came with going against prohibition. Gangs led by people such as Al Capone began illegal production of alcohol, supplying speakeasies. This in turn led to other illegal activities such as protection racketeering, and events including the St Valentines Day massacre where seven members of Moran's gang were killed by members of Al Capone's. Finally, there was not enough support amongst the general public for prohibition, who continued to visit speakeasies and brewed their own alcohol - moonshine - whoch could be deadly. In 1929, the Wickersham report stated prohibition was not working and it was repealed.
