De Klerk began a systematic dismantling of many of the building blocks of apartheid. He opened South African beaches to people of all colors, and stated that the Reservation of Separate Amenities Act would soon be repealed. Since 1953 this act had enforced what was known as “petty apartheid,” segregating parks, theaters, restaurants, buses, libraries, toilets, and other public facilities, according to race. In November, he announced that the National Security Management System, a secret structure set up under P. W. Botha to combat anti-apartheid forces, would be dissolved.
