The first question, in fact, our current historical division mainly refers to the method of dividing history in Western Europe and the United States, and divides the history of China into primitive society, slave society, feudal society, semi-feudal and semi-colonial period, and then New China. This is the current mainstream dating method, not the ancient history and modern history you mentioned, but some very rough divisions. The time is roughly as follows:

Primitive Social Period: Three Emperors and Five Emperors

Slave society period: summer-spring and autumn

Feudal social period: Spring and Autumn Period-1840 Before Qing Dynasty.

Semi-feudal and semi-colonial: Qing dynasty 1 840-19491June1.

New China period: 1 949 65438+1October1present.

The second question is that this dating method is the mainstream dating method in Europe and America, and it is based on productivity and production relations. For example, the relationship of production in slave society is the relationship between slave owners and slaves, and the relationship of dating in feudal society is the relationship between landlords and farmers.

The third question is divided according to the length of time from now. Combined with the development of productive forces, it can be divided into ancient times, classical times, gunpowder times, enlightenment times, modern times and information times. This is mainly divided according to the development of a productive force, according to the level of productive forces, and according to the distance from the present time, which can be divided into ancient, medieval, enlightenment, great navigation, modern and modern times.

The fourth question, the division of ancient world history is based on the description of the third question above, mainly based on the development of productive forces and technical level! It is also the most mainstream division!

I hope the above answers can help you!
