In history, only China has a periodic law of the rise and fall of dynasties, and many people must know the songs of past dynasties by heart. Xia, Shang, Zhou, Qin and Western Han Dynasties. Three Kingdoms, Jin Dynasty, Southern and Northern Dynasties. Sui, Tang, Five Dynasties and Ten Kingdoms. Liao, Song, Xia, Jin, Ming and Qing Dynasties. Many of these dynasties can't get rid of about 300 years. The ups and downs of fate change once. So it is called the periodic law of the rise and fall of dynasties, or the periodic rate. The former refers to regularity, while the latter refers to frequency.
In this cycle, every dynasty that can win long-term stability for 200~300 years begins with breaking the original social structure and achieving relative fairness through the "land equalization system". In the agricultural society, "field" is the land and the most important means of production, just like today's capital.
Characteristics of historical periodic law
One is periodicity, that is to say, "the law of historical periodicity" is a cyclical historical law. "The deer dies in Qin, and the snake prospers in Han", and the ups and downs are endless.
The second is universality. From Xia, Shang, Zhou, Qin and Han dynasties to Tang, Song, Yuan, Ming and Qing dynasties, no one can really jump out of this periodic law. As Mr. Huang Yanpei said: "A person, a family, a group, a place or even a country, many units have no power to jump out of this cycle rate. In a history, there are also people who died and lost their political interests, and there are also people who pursue honor and disgrace. In short, they failed to jump out of this cycle rate. "
The third is rapidity, that is, the so-called "its prosperity is also rich, and its death is also sudden." Many dynasties in China's history were very short, such as Qin Dynasty and Sui Dynasty, which were only 15 years and 29 years respectively. It can be said that their life is also sudden and their death is also rapid. During the Southern Dynasty 170 years, the four dynasties of Song, Qi, Liang and Chen changed like a lantern. With the Southern and Northern Dynasties, the so-called Five Dynasties period, but before and after more than 50 years, the world changed hands, and Hou Liang, Tang Dynasty, Jin Dynasty, Han Dynasty and Zhou Dynasty followed.
