Beer in the United States
On January 16, 1919, the Eighteenth Amendment to the United States Constitution was enacted into law, creating the Prohibition era, wherein the production, sale and transportation of alcoholic beverages was made illegal. All legal American brewing came to a halt when prohibition was imposed, though the earlier temperance movement had already reduced the number of breweries significantly. Only a few breweries, mainly the largest, were able to stay in business by manufacturing near beer, malt syrup, or other non-alcohol grain products, in addition to soft drinks such as colas and root beers. Production and shipping of alcohol was largely confined to illegal operations that could deliver compact distilled beverages—smuggled rum and domestic moonshine—more efficiently and reliably than bulkier products such as beer.
Anti-Saloon League
It was a key component of the Progressive Era, and was strongest in the South and rural North, drawing heavy support from pietistic Protestant ministers and their congregations, especially Methodists, Baptists, Disciples and Congregationalists. It concentrated on legislation, and cared about how legislators voted, not whether they drank or not. Founded as a state society in Oberlin, Ohio, in 1893, its influence spread rapidly. In 1895, it became a national organization and quickly rose to become the most powerful prohibition lobby in America, overshadowing the older Woman's Christian Temperance Union and the Prohibition Party. Its triumph was nationwide prohibition locked into the Constitution with passage of the 18th Amendment in 1920. It was decisively defeated when Prohibition was repealed in 1933.
