”Prohibition had a lot of unintended consequences that backfired on the people who worked so hard to establish the law,” said Harvard history professor Lisa McGirr, whose 2015 book “The War on Alcohol” examines Prohibition’s political and social repercussions.

“It helped to activate and enfranchise men and women who had not been part of the political process earlier,” she said. “That was not the intention of Prohibition supporters.”

Ratification of the 18th Amendment in 1919, which set the stage for Prohibition’s launch a year later, culminated a century of advocacy by the temperance movement. Leading forces included the Women’s Christian Temperance Union, the Anti-Saloon League and many Protestant denominations. Prohibition supporters assailed the impact of booze on families and the prominent role that saloons played in immigrant communities.
