[Introduction to World History] (6) African nations and cultures from BC 10000 to BC 1000.

The origin of human beings originated in sub-Saharan Africa, but there are few historical records later, which may also be related to the fact that its historical sites are found less. Some historians even suspect that Africa's national culture is developing slowly. Facts have proved that there are some misunderstandings in this view.

Before 1 10,000 BC, most parts of the Sahara were wet, welcoming the earliest inhabitants and fishermen in Africa. From 10000 BC to 2000 BC, immigrants lived in the northern Rift Valley in East Africa and the Nile Valley in Sudan, including Ghana. The fishing gear used by fishermen is a biting harpoon.

Around 7000 BC, a large number of cattle began to graze near the Huojia Mountain in the Sahara in western Egypt. The Nile Delta has begun to introduce wheat and barley technology from West Asia. The situation in Sudan is somewhat special. Most of them are sorghum and all kinds of millet grown by themselves.

From 4000 to 3000 BC, as the climate of the Sahara desert became dry, farming began to enter the Nile Valley. In 2000, due to the development of cattle industry and tropical crops, the population of Sudan increased significantly. In the last few centuries BC. The Nile Valley in Sudan, the Ethiopian Plateau and the Nile Delta are all urban centers.

In North Africa, Egyptian civilization rose in isolation. In 4000 BC, Egypt began to use copper, and in 3000 BC, it turned to bronze. It was not until 1000 BC that iron was used. Then Egypt declined. Kush Kingdom prospered in the Nile Valley of Sudan. Later, it was defeated by the Ethiopian kingdom of aksum.

Black Africa always gives people a reverie, and the splendid civilization and history of ancient Egypt sometimes seem to have faults. The long-term colonization of Africa by the west and the history of blood and tears of hundreds of millions of slaves. An amazing number of wild animals on the African savannah. Black Africa is now on the fast track of economic development, thanks to the win of China's reciprocal economy, which ushered in a new page.
