Apartheid was a South African hierarchical system based on the separation of blacks and other nonwhites from the whites who controlled South African society and government. Apartheid (literally apart-ness comes from the Afrikaans word meaning "separation," and is officially applied to the systematic government policies enacted by the ruling National Party, which was dominated primarily by Afrikaners (people of Dutch ancestry in South Africa). Apartheid officially existed as government policy in South Africa from 1948 until 1994.
In his response to Professor Kroonstad of South Africa, Kelvin R. Throop (in the guise of "Beals Becker") disputed Kroonstad's proposal that South Africa deserved special status in the U.N. simply because humans developed in what is now South Africa. Further, the Apartheid regime convinced Becker that very little evolution had taken place in the area for some time. Becker concluded by pointing out that the original humans were almost certainly black.
Becker's valediction was "Primevally, Beals Becker".
Upon the Race's conquest of South Africa in 1942, they abolished the then-developing system of racial discrimination they found there. Classifying Big Uglies on the basis of their skin color made no sense to the Race's commanders, and freeing one group of Tosevites from oppression by others was a convenient way of gaining support.
