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.
Prohibition
Between 1880 and 1890, although several states enacted local option laws that allowed counties or towns to go dry by referendum, only six states had statewide prohibition by state statute or constitutional amendment. The League, with the support of evangelical Protestant churches and other Progressive-era reformers continued to press for prohibition legislation. Opposition to prohibition was strong in America's urban industrial centers, where a large, immigrant, working-class population generally opposed it, as did Jewish and Catholic religious groups. In the years leading up to World War I, nativism, American patriotism, distrust of immigrants, and anti-German sentiment became associated with the prohibition movement. Through the use of pressure politics on legislators, the League and other temperance reformers achieved the goal of nationwide prohibition by emphasizing the need to destroy the moral corruption of the saloons and the political power of the brewing industry, and to reduce domestic violence in the home. By 1913 nine states had stateside prohibition and thirty-one others had local option laws in effect, which included nearly fifty percent of the U.S. population. At that time the League and other reformers turned their efforts toward attaining a constitutional amendment and grassroots support for nationwide prohibition.
