6. Amending the Constitution

Since 1876, a congressional resolution for a Prohibition amendment was introduced in every Congress, but none ever made it out of committee. The growing political clout of the Anti-Saloon League changed that pattern. In 1906, the ASL launched a campaign to ban the sale of booze at the state level.
Within a decade, 23 out of 48 states had enacted laws against saloons, and some had even banned the manufacture of alcohol in the first place. Sensing a political tailwind behind their back, and the opening of a window of opportunity before them, the ASL shifted gears and set its eyes on nationwide Prohibition. On December 18th, 1917, Congress approved the submission to the states of the Eighteenth Amendment to the US Constitution, banning the manufacture, sale, or transportation of liquor.
