1. Location: Ancient Asian-African civilizations were mainly located in large basins, such as ancient Egypt in the Nile Valley, ancient Babylon in the Two Rivers Valley, ancient India in the Indus Valley, ancient China in the Yellow River Valley and the Yangtze River Valley. Natural conditions such as climate and water resources in these areas are suitable for agricultural cultivation, so these areas have also become important birthplaces of human civilization.
2. Political economy: Ancient Asian and African civilizations established unified slave countries, such as ancient Egypt, ancient Babylon, ancient India and ancient China. The development of these countries is inseparable from slavery. In addition, the economic basis of these civilizations is mainly agricultural economy, which is very suitable for agricultural work because of the fertile land, abundant water resources and mild climate in the basin.
3. Culture: Ancient Asian and African civilizations have unique cultural characteristics, such as pyramids, hieroglyphs and myths and legends in ancient Egypt, hanging gardens in Babylon, code of hammurabi, Buddhism and Hinduism in ancient India, and Confucianism, Taoism, Buddhism and France in ancient China. These cultural characteristics are of great significance to these civilizations at that time and have a far-reaching impact on the development of later civilizations.
These are the unit characteristics of ancient Asian and African civilizations, but these characteristics are not completely possessed by all Asian and African civilizations, and each civilization has its own uniqueness.
