Chicago
The ratification of the 18th amendment to the Constitution in 1919 made the production and sale (including exportation) of alcoholic beverages illegal in the United States. This ushered in the beginning of what is known as the Gangster Era, a time that roughly spans from 1919 until 1933 when Prohibition was repealed. The 1920s saw gangsters, including Al Capone, Dion O'Banion, Bugs Moran and Tony Accardo battle law enforcement and each other on the streets of Chicago during the Prohibition era. Chicago was the location of the infamous St. Valentine's Day Massacre in 1929, when Al Capone sent men to gun down members of a rival gang, North Side, led by Bugs Moran.
Prohibitionism
Acts of prohibition have included prohibitions on types of clothing (and prohibitions on lack of clothing), prohibitions on gambling and exotic dancing, the prohibition of drugs (for example, alcohol prohibition and cannabis prohibition), prohibitions on tobacco smoking, and gun prohibition. Indeed, the period of Prohibition in the United States between 1920 and 1933 due to the Eighteenth Amendment and the Volstead Act often is referred to simply as "Prohibition", as is the "War on Drugs" that succeeded it. 
An additional example, called "nettle war": Since 2002 in France the sale of nettle liquid manure was prohibited, and since 2006, unauthorized plant protection products (such as nettle liquid manure) to sell, own and operate. Even advertising and recommendations for these products were not allowed. Only since 2011, it was legalized again. The film by Arte about it was completed in 2010 ("Nettle-war, mysterious plants - Nettle", 42:04 minutes)
