Linfred Schuttler gave the final program of the year; it was a narrative regarding early prohibition years in South Dakota.
The national era of prohibition didn't occur until 1919, when the 18th Amendment to the U.S. Constitution was ratified by 36 states. While it didn't ban the consumption of alcohol, it placed severe restrictions that made consumption seemingly impossible. It took effect in 1920, but was circumvented in a variety of ways.
More than a decade later, in 1933, the government came to recognize the futility of the law, and prohibition ended with the ratification of the the 21st Amendment. It is the sole case where an amendment to the U.S. Constitution has been repealed.
Schuttler's May presentation focused on earlier "temperance" laws in South Dakota. He recounted how three different periods of prohibition occurred between 1889 and 1933.
