In 1928, a few years after unionization, South Africa adopted its first national flag, which consisted of a past version of the flag of the Netherlands combined with miniature flags representing the different colonies that came together to form South Africa. After the end of apartheid, South Africa adopted a new national flag in 1994, as the previous flag had come to symbolize the apartheid regime.
Since 1994, white supremacists in South Africa and elsewhere around the world, including the United States, have adopted the 1928 flag as a symbol of white supremacy.
