Primitive society (about 1 million 700 thousand BC - twenty-first Century BC) was the first community established after the human production, which is the first stage of human history.
So far, it has not been found in the world which people have not experienced the primitive society. Man appeared, and the primitive society came into being. But its demise around irregular. In the primitive society, the human productivity level is very low, and the production material is public ownership. With the improvement of the level of productive forces, after the emergence of surplus products, there is a gap between the rich and the poor, and the private ownership system, the original joint distribution and joint work of the relationship was destroyed, and was replaced by the class society.
