Why did the Afrikaans decide to settle Africa in the first place? Surly they knew that they would eventually enter into conflict with the natives. Why not do what they did in New Zealand and much earlier in the United States. They made treaties with the natives.
shareWhen the Dutch arrived, they did not know about any natives. When they met the first natives, it was with the Khoisan (the so-called Brown people or Coloureds of South Africa), not the Bantu people (the black people of South Africa). They intermarried and lived more or less in peace (as much as settlers did in those days). Soon more Europeans came to the Cape and they wished to distance themselves from their kin in Europe, who forced many of them to leave due to religious prosecution. They then called themselves Afrikaners (Afrikaans being the language of the Afrikaners) in order to differentiate themselves.
Then finally, the Afrikaners were colonised by the British and became even more nationalistic and wished for independence. During this time the British declared war against the Xhosas and Zulus. The British also had the power to make laws as they saw fit (language of instruction in schools, the abolisment of slavery etc). Some of the Afrikaners who then went north to find their own countries (the so-called Boer Republics) came into contact with the Bantus (the black people). This is where their first major conflicts came, after almost 200 years of already living in South Africa.
Diamonds and gold were then discovered in the Boer Republics. The British then once again moved against the Afrikaners (or the Boere as they were known in the North) and declared war. The Boere admitted defeat after their women and children were placed in concentration camps (where many died).
Finally, the Afrikaners (the Cape Dutch and the Boere of the North)began to unite and became so nationalistic, that they implemented a social system where they could live... apart. Apartheid. The British (by now the English South Africans) also voted for this, as they would financially benefit as well.
This is certainly not an excuse of the horrible things that were committed during Apartheid, but it is the beginning of an explanation as to why it happened in the first place.
The Afrikaners never went to New Zealand or the USA (I assume you mean the Dutch explorers). Different people, different places and different outcomes, I assume.
