Date: 30 September, 1926

The Immorality Act, a key component of Apartheid legislation, was passed into law. The law made it illegal to have sex with people of different races in the area of marriage as well as casual sex. The law was followed by a ban on mixed marriages and a ban on sexual relations between Black and White people. The law was repealed by P W Botha in 1985 signaling a growing crisis and end of Apartheid.
