Why are people in some African countries not black?

Mainly due to historical reasons and latitude factors.

The ethnic groups in North Africa (mainly including Egyptian, Libyan, Moroccan, Algerian and Tunisia) are mainly white, of which more than 70% are Arabs, and Arabs belong to white in ethnic classification. The main reason is the expansion of the Arab Empire in history, and the whole of North Africa was incorporated into the empire territory. Further on, Persia and the Roman Empire once occupied the whole of North Africa, attracting huge Eurasian immigrants.

Let's talk about South Africa. The population of South Africa is 38,565,654,38+0,000, accounting for 79.2% of the population, 4,379,200 people of color, accounting for 9% of the population, 65,438 Indians/Asians+0,243,500 people, accounting for 2.6% of the population and 4,000 whites. Black people mainly include Zulu, Xhosa, Swazi, Tswana, North Soto, South Soto, Kanga, Venda and Ndebele. White people are mainly South African whites of Dutch descent (about 57%) and British whites (about 39%). Colored people are a mixture of whites, aborigines and slaves during the colonial period. Asians are mainly Indians (about 99%) and China. As can be seen from the above, the main historical reason for whites and colored people is European colonial rule, and Asians are mainly immigrants for more than a century. However, due to the dominance of white people in South Africa, most of them live in cities, while the vast majority of black people are either urban poor or rural people, so most of them appear on TV in South Africa.
