Quick Summary

In 1946, Indiana faced a resurgence of white supremacist groups like the Ku Klux Klan and neo-Nazi Columbians. In response, Indiana passed an anti-hate law in February 1947 that criminalized "racketeering in hatred," imposing up to ten years imprisonment and a $10,000 fine for actions promoting racial or religious hatred leading to public disorder. This measure was widely supported and influenced similar legislation across the United States. The Indiana law aimed to protect civil rights by penalizing those who spread hate that incited violence or disruption.

Story summary

In the 1940s, Indiana faced a resurgence of white supremacist groups like the Ku Klux Klan and a new neo-Nazi organization called Columbians, Inc. After The Indianapolis Star exposed these efforts in 1946, Indiana's leaders responded by passing an "anti-hate" law to penalize "racketeering in hatred," which included spreading racial or religious hate that could lead to riots, violence, or denial of civil rights. This was the first such legislation aimed at preventing racist gatherings and punishing hate group leaders. The measure defined the crime as acting with malice to create, advocate, spread, or disseminate hatred based on race, color, or religion if it threatened public order or safety.
